3 Different Shapes Lithium Battery Structure

At present, there are three main types of mainstream lithium battery structures, namely, cylindrical, rectangular and pouch cells. Different lithium battery structure means different characteristics, and each has its own advantages and disadvantages.

1. The cylindrical lithium battery structure

The round lithium battery refers to the cylindrical lithium battery. Because the history of the 18650 cylindrical lithium battery is quite long, the market penetration rate is very high. The cylindrical lithium battery adopts various mature replacement processes, the degree of automation is high, and the product mass transfer is stable. The cost is relatively low. Cylindrical lithium batteries are available in a variety of models, typically 14650, 17490, 18650, 21700, 26650, etc. Lithium-ion batteries are widely used in lithium batteries in Japan and South Korea. There are also large-scale enterprises in China that produce cylindrical lithium batteries.

With the further expansion of the electric vehicle market and the continuous improvement of the cruising range, the vehicle manufacturers have put forward higher requirements on the energy density, manufacturing cost, cycle life and product additional attributes of the power battery.

2. The rectangular lithium battery structure

Rectangular lithium battery usually refers to an aluminum shell or steel shell rectangular battery. The expansion rate of the rectangular battery is very high in China. It is the rise of automobile power battery in recent years. The difference between vehicle cruising range and battery capacity is becoming more and more obvious. The aluminum-shell rectangular battery with high battery energy density is mainly because the structure of the rectangular battery is simple, unlike the cylindrical battery, which uses high-strength stainless steel as the housing and accessories such as explosion-proof safety valves, the overall accessory weight is light. The relative energy density is higher. Rectangular batteries have two different processes, winding and lamination.

However, since rectangular lithium batteries can be customized according to the size of the products, there are thousands of models on the market, and because of too many models, the process is difficult to unify. Rectangular batteries are no problem for use on ordinary electronic products, but for industrial equipment products that require multiple strings and parallels, it is best to use standardized production of inserted lithium batteries. This production process is guaranteed, and it is easier to find alternatives later. battery.

3. Pouch Cell

The key materials used in pouch cell—positive materials, anode materials, and separators—have little difference from traditional steel and aluminum-shell lithium batteries. The biggest difference is the flexible packaging material (aluminum-plastic composite film). It is the most critical and technically difficult material in the pouch cells. The flexible packaging material is usually divided into three layers, namely an outer resist layer (generally an outer protective layer composed of nylon BOPA or PET), a barrier layer (intermediate aluminum foil) and an inner layer (multifunctional high barrier layer). The packaging material and structure of the pouch cell gives it a number of advantages.

3.1 Safety performance

The pouch cell is packaged in aluminum plastic film. When a safety problem occurs, the pouch cell will generally be blown apart, unlike the steel shell or the aluminum shell.

3.2 Lightweight

pouch cell weight is 40% lighter than steel shell lithium battery of the same capacity, 20% lighter than aluminum shell lithium battery.

3.3 The internal resistance is small

and the internal resistance of the pouch cell is smaller than that of the lithium battery, which can greatly reduce the self-consumption of the battery.

3.4 The cycle performance is good

For the cycle life of the pouch cells longer, and the attenuation of 100 cycles is 4% to 7% less than that of the aluminum case.

3.5 Flexible design

variable shape and any shape can be thinner, such as the following:

●Ultra-Thin Battery●Curved Battery●Round Batteries●Triangle Battery●Hexagon Battery●Ultra Narrow Battery●C Shape Battery●D Shape Battery●Polygonal Battery●Rectangle Battery

We can customize and develop novel battery models according to customer needs.

The shortcomings of the pouch cell are poor consistency, high cost, and easy liquid leakage. The high cost can be solved by large-scale production, and the leakage can be solved by improving the quality of the aluminum-plastic film.

4. Comparative analysis of technical characteristics

4.1 Battery shape

Rectangular lithium batteries can be of any size, so they are not comparable to cylindrical batteries.

4.2 Rate characteristics

Cylindrical lithium battery soldering multi-pole process limitations, so the rate characteristics are slightly worse than the rectangular multi-pole solution

4.3 Discharge platform

The same positive electrode material, negative electrode material, and electrolyte are used, so the theoretical discharge platform is consistent, but the internal resistance of the rectangular battery is slightly dominant, so the discharge platform is slightly higher.

4.4 Product quality

The process of cylindrical lithium battery is very mature, the probability of secondary slitting defect is low, and the winding process is higher than the lamination process maturity and automation. The lamination process is still in semi-manual mode, so the quality of the battery There are adverse effects.

4.5 Tab welding

Cylindrical lithium battery poles are easier to solder than rectangular lithium batteries, and rectangular batteries are prone to cause solder joints to affect battery quality.

4.6 Pack grouping

The circular battery is relatively easy to use, so the packing scheme is simple, the heat dissipation effect is good, and the rectangular battery pack should solve the problem of heat dissipation.

4.7 Structural features

the chemical activity of the rectangular battery is poor, and the performance of the battery for long-term use is more obvious.

In short, whether it is cylindrical, rectangular or pouch cell, the current rapid development is because they are well applied in their respective application areas. Domestic battery manufacturers are predicting that the rectangle will become the mainstream of the battery, but the battery application manufacturer represented by GREPOW is constantly innovating in technology, the battery energy density is continuously improved, and the battery performance is more excellent.

10 precautions for lithium polymer battery customization

If the customized information provided by the customized lithium polymer battery is incomplete, it will not only affect the work efficiency but also cause misunderstanding of poor working ability. More importantly, it may cause a large safety hazard to the product, so GREPOW is for the lithium polymer battery. Customization summarizes a few experiences for battery customers to refer to, whether it is to do project product design or custom battery solution report will be very helpful.

1. The width dimension of the lithium polymer battery flange

Because the polymer battery generally adopts single-folding or double-folding technology, the battery edge will be loosened when the battery is folded. For example, the original folding edge is 20mm wide, and the flange will be loosened after the folding. 20.3mm or so, don’t worry about it at this time, this is also the time to test the product designer, remember to leave more space or leave battery space.

2. The thickness of the finished lithium-polymer battery

Since the polymer battery itself has expansion property, all the soft pack batteries will expand after being charged and discharged for a certain number of times, so the thickness expansion ratio should be considered in the design of the product, and the force and force card of the caliper card battery thickness is used, and the thickness is There will be changes, do not believe that you can find a lithium polymer battery caliper to test the thickness, at least 10 wire thickness deviation.

3. Battery material system

Most of the digital products use ternary battery material systems, such as mobile phones, tablet computers, Bluetooth headsets, etc., while the high-capacity polymer batteries used in vehicles use more lithium iron phosphate systems; the ternary materials are normally 3.7V. The voltage, while the iron-lithium material is 3.2V.

4. The capacity of the lithium polymer battery

A certain capacity can be achieved in the corresponding battery space, but not 100% of this battery capacity segment, so the custom battery manufacturer will give the upper and lower limits of the battery capacity; for example, when evaluating the manufacturer The design capacity given is 100mAh, and 95mAh will appear in the actual production process. These are normal, because the design will have positive and negative tolerances, so don’t bite the word to lift it.

5. lithium polymer battery voltage system

High voltage and common voltage must be distinguished. For example, when using a high voltage 4.35V (full charge) voltage system, it must be clearly stated in the specification of the lithium polymer battery, and the ordinary voltage is 4.2V (when fully charged). If you do not explain clearly that we will generally customize the 4.2V voltage system, it is recommended that you understand the power supply scheme of your product chip to see what voltage system is suitable.

6. Battery operating current rate

For example, some Bluetooth headset batteries have a relatively small operating current. Generally, 0.2C discharge is enough; while the RC battery operating current is generally about 10A. For example, a 600mAh battery for a model airplane can continue to be discharged at 20C. Use on, so be sure to know the working current when customizing the battery, it is best to continue how many A, how much A current to work instantly.

7. Battery pole ear

The lithium-polymer battery should pay attention to the overall size of the battery, especially the positive electrode ear size of the polymer battery, because the positive electrode of the soft pack battery is particularly fragile, and it is easy to break when folded several times. Generally, the positive electrode is laser-transferred to nickel, when in use. According to experience, the number of bending of the positive ear should not exceed 3 times. If the battery capacity is large enough, a thick and wide lithium polymer battery customized solution can be used to solve the problem of easy breakage of the ear.

8. Polymer battery output

Generally, the output of small polymer batteries is mostly wire, and some of them are output terminal wires of the battery, which involves the corresponding types of terminals, such as JST terminal, PH terminal, 1.25 terminal, 2.0 terminal, 2.54 terminal, 3.96 terminal, etc. Etc., the other terminals are also positive and reverse. If the wrong direction is connected, the product will not work and even burn out the product. If you are not sure, you can provide the plug-in socket and battery power input circuit to the other party, or face-to-face communication. Basically, it can ensure that the lithium polymer battery can be customized in one time without error.

9. Battery pack finished product

Most of the PACK finished batteries are equipped with protective plates, wires, plug wires, casings, etc., and some special ones may need to add FPC soft cable, such as Apple mobile phone batteries, some need to add plastic shell, such as walkie-talkie battery; Others need to add communication protocols, such as battery for vehicles; so these items must be clear in the process of customizing the lithium polymer battery, involving high current, shell and shell color, silkscreen, communication protocol, etc. The content is more detailed, the better, the more detailed the more can reduce the mistakes.

10. The outer shell of the polymer battery

Do not deliberately scratch the surface of the battery, because the surface of the lithium polymer battery is very fragile and it is easy to scratch if accidentally. The quality of the customer should not scratch the surface of the battery with the fingernails during the incoming inspection. We should put an end to these unnoticed behaviors.

Please support all manufacturers of lithium polymer battery custom, please communicate more details, more inclusive, more cooperation. I hope this article can help customers with customized battery. Of course, these can be extended to other products. I hope that the 10 factors of lithium polymer battery customization will be inspiring.

What are Military Smart Wearable Devices?

With the integration and the development of semiconductor technology, relying on the mobilization and comprehensive popularization of the Internet, the intelligent and flexible breakthrough of the manufacturing industry, Google wear glasses, smart bracelets, VR and other smart wearable devices have appeared one after another. In our vision, we have entered people’s lives. These smart wearable devices can not only help people to feel the external environment they are in, but also realize the seamless connection and communication of human-machine information with the help of computers, the Internet or other sensing devices. With the gradual improvement of people’s living standards and consumption levels, people’s requirements for smart wearable devices are becoming more and more personalized and diversified, and market demand and scale are becoming more and more urgent and expanding.

Military smart wearable device development

Driven by the civilian sector, under the trend of the future battlefield gradually turning to informatization and digitization, countries are vying to invest a large amount of human, material and financial resources to introduce smart wearable technology into the military field and to develop a military plan for smart wearable device systems. , initiated the development and application of related technologies, and achieved certain results.

Such as the US Army’s “Army Warrior Individual Soldier System”, Russia’s “Wolf Soldier 2000 Individual Soldier Combat System”, France and Italy’s “Future Infantry Individual Combat System”, Britain’s “Heavy Boxing System”, and South Korea’s “Future Force” The Warriors System, Japan’s “Next Generation Melee Information Sharing System”, India’s “Future Infantry Combat System”, Germany’s “IdZ Combat System”, etc., almost all of these combat systems use a variety of smart wearable devices.

Military smart wearable devices

Among the above-mentioned individual soldier systems,  some military smart wearable devices are more prominent, mainly as follows:

(1) Smart soldier uniforms

Wearables and sensors have been sewn into soldier uniforms and ergonomically designed to match forces. However, while increased computing power, artificial intelligence systems, and advanced processing speeds are expected to bring prior advantages to operations, greater reliance on computer networks require advanced security technologies.

Almost all combat systems will rely on the network. Sensors, weapons and network technologies will all rely on secure computing to perform the most advanced combat missions. The wearable device worn by the soldier will immediately connect the target information, drone, and enemy tracking data. Wearables and sensors have been sewn into soldier uniforms and ergonomically designed to match forces. However, while increased computing power, artificial intelligence systems, and advanced processing speeds are expected to bring prior advantages to operations, greater reliance on computer networks require advanced security technologies. Soldier wearables, embedded sensors, night vision goggles, and wireless communication links require advanced security measures to succeed in battle.

In the late 1990s, the Georgia Institute of Engineering and Technology developed a “smart shirt” that was used to monitor and monitor the physical condition of US soldiers.

(2) wearable exoskeleton

In 2000, Sarcos developed the “XOS” series of wearable exoskeleton systems for the US Army Warrior Individual System.

(3) Smart helmet

Raytheon developed a smart helmet for the US military in 2012, which can be used by the aviation crew. The helmet is equipped with a computer and sensor display that allows soldiers to view a variety of graphical data, digital maps, intelligence, position, and more. Moreover, the device on the helmet can also cooperate with the thermal imaging weapon sight mounted on the weapon in the hand, so that the soldier hides in the shooting corner of the other party and reconnaissance the surroundings.

(4) Smartwatches

Smartwatches can help Air Force pilots, crew members identify dangerous fatigue. Always tired during flight, or this is a more systematic problem for the Mobile Air Force. Sustained fatigue can greatly affect the reflex required by the pilot to maintain the stability of the aircraft, as well as the coordination required to refuel, land or handle an emergency in the air.

The system includes a watch that measures the pilot’s circadian rhythm or an internal 24-hour clock that regulates the person’s sleep-wake cycle. Of course, the smartwatch battery life should be long enough. After the flight, many people will feel the time difference, because when they should fall asleep or wake up, their mind and body will be different. So one thing that can be seen is how many crew members are flying in the opposite direction of their biological clock.

The combined data can act as a sleep aid. When the crew entered other countries, maybe he had been awake for 27 hours, but the watch told him, ‘Hey, your circadian rhythm has reached its lowest point, now it takes two hours of sleep,”

At the same time, the development of smart wearable technology has also attracted great attention in China. Relevant research institutions in China have begun to study military wearable devices from the shallower to the deeper. For example, the “Dragon Warrior” individual combat system, the individual soldier status monitoring system, the human body power supply equipment and other military intelligent equipment products developed by Chinese military scientists.

The war mode has changed due to a large number of applications of smart wearable equipment. Under the new war mode, the combat capability of the individual soldier system directly determines the strength of the overall combat capability of the battlefield, which makes the role of smart wearable devices in the military field more prominent. At the same time, we know that smart wearable devices are typical equipment of individual soldier systems. If a series of diversified products are used to install troops, the demand will be incalculable, so the market application prospects are very good.

Analysis of the development of the military field

Although the role of military smart wearable devices in the military field is becoming more and more prominent, the market prospects are difficult to estimate, but the development of the following three aspects needs to be broken.

(1) Power supply

For most smart wearable devices, the battery is its core component, and without the electric wearable device, it doesn’t matter, so the battery is still the biggest constraint to its use. Efficient energy technology or energy conversion technology is the winner of this problem, but it should be noted that these technologies must combine the needs of miniaturization and lightweight wearable devices.

Fortunately, in order to break through the above problems, GREPOW has developed a special battery that is customized to fit into any and all spaces in a product. In order to provide the best efficiency, shaped batteries can be made to fit into even With our proprietary formula and high discharge-rate technology, you can maximize the run time and use of your product. Even in harsh environments, shaped batteries can be utilized at low temperatures of -50°C to 50°C and at high Temperatures of 20 ° C to 80 ° C.

(2) Sensing and interaction

The battlefield environment is complex, such as desert, high humidity, high heat, high salt spray, corrosive liquid and other high-level battlefield environments, which has certain destructive, interference and corrosive effects. How to effectively complete the transmission, transmission, and transmission of information, and correct Identification is another problem faced by military wearable devices. Therefore, sensing equipment and high-efficiency human-computer interaction technology with the certain anti-destructive ability and corrosion resistance are particularly important.

(3) Security encryption protection

Once a powerful military wearable device falls into the enemy, how to prevent the device from leaking and prevent the enemy from forging information to interfere or induce the war command is a security problem faced by the military wearable device. Therefore, the importance of constantly updated security protection technologies and encryption technologies in military wearable devices has become self-evident.

many US military and industrial innovators are working on advanced lightweight encryption technology designed to protect computer systems and integrated networks that operate on the edge of the battle.

Encrypted Sensors is a recently patented encryption technology designed to dramatically increase in the security and efficiency of network-dependent combat systems.

According to developers, this emerging technology embeds pre-programmed computer chips into the hardware itself without relying on software for encryption. The so-called Field Programmable Gate Array (FPGA) technology does not use software and computer processing units for control like traditional encryption programs.

In individual combat, reducing computational processing and increasing efficiency can make smaller, portable technologies possible. In addition, these new encryption methods can connect multiple devices through a central hub, since no software is required.

Encrypted Sensors’ work is designed to reduce vulnerabilities associated with traditional encryption methods that use larger data “blocks” and rely on mathematical formulas. Using non-mathematical encryption techniques can bring substantial security benefits.

With the development of technologies in the fields of security protection, sensors, power supply, etc., and the advancement of manufacturing processes, the application of smart wearable devices in the military field will inevitably lead to international competition, and will certainly play a huge role in the future battlefield. Amazing effect.

Apple Smart Ring- Real Life Lord of the Rings!

Apple media Appleinsider reported that Apple may be developing the next wearable device – Apple Smart Ring. It may have some of the features of the smartwatch Apple Watch that can manipulate nearby wireless devices.

The US Patent and Trademark Office certified Apple’s patent, called the “device, method and user interface for wearable electronic rings.” According to patent data, the smart ring consists of a processor, a wireless transceiver, a power supply, and a microphone. It also includes other sensors that replace the user’s gestures, as well as the dial of the Digital Crown of the Apple Watch.

The tactile actuator inside the ring can provide force feedback and “communication direction information” to the user; the motion sensor can sense the writing action; the biosensor can track the health data; the wristband also supports NFC communication, and the identity can be connected via the wireless connection. The information is transmitted to the second device, and some are used to unlock the Mac.

Apple Ring Demo Picture Source: Apple Patent Report

Apple-defined gestures include pointing a finger with a ring to another device for a wireless connection, or a swipe or flick gesture to change the selection in the menu, and rotating the finger to indicate the rotation of the device screen, and so on. When the user touches or taps the surface, it vibrates slightly, giving the user force feedback.

Like the Apple Watch, Apple may also define it as an auxiliary health product. Because the multiple transmitters included in the device allow for more accurate motion detection. In addition, it also has a touch screen that supports text input methods similar to Apple Watch.

Apple submits a large number of patent applications every week. Not all concepts are completely converted into final products, but Appleinsider believes that it does indicate the areas of interest that Apple is researching and developing.

Earlier in 2015, Apple submitted a patent application saying it was developing a wearable smart device smaller than the Apple Watch, called the “Apple Ring.” The user can wear a ring with a touch display on the index finger and intervene with the thumb.

For Apple, the pursuit of smaller and lighter wearable devices is a reasonable trend. Although Apple Watch is considered a successful work, there are still many people who prefer mechanical watches and think it should be embarrassing. Naturally, if a smart ring can achieve the same effect in a more inconspicuous way. However, from the current patent picture, it seems that this ring is not too good-looking – at least similar to the traditional ring.

In addition, it is worth mentioning that Apple is not the only big technology company that is developing smart rings. Amazon recently also launched a smart ring called Echo Loop, which has two microphones that can be activated by pressing a button. When you need to connect to Alexa, you still need to rely on another separate host device for behavior processing and Data Connections.

Development trend

The purpose of smart wear is to explore a new way of human-computer interaction, which provides consumers with exclusive and personalized services by wearing smart devices on the human body. Through the development of mobile Internet technology and low-power chips, the core hardware technology of wearable devices such as flexible circuit boards has matured, and some wearable devices have gradually moved from conceptualization to commercialization, and new wearable devices have been continuously introduced.

Fashion glasses will become smarter

Fashion glasses will not only look cool, but they will also become smarter. Google Glass may be prepared to be hated by San Francisco barbers and non-technical people, but it is undeniable that the rise of smart glasses is a major factor in searching for giants.

Sony, Vuzix and many other vendors have launched or are developing smart eyewear-based wearables.

Although most of these devices are not very aesthetically pleasing, smart glasses have begun to look more and more pleasing to the eye. Google glasses are equipped with stylish frames, some of which are from the famous fashion designer Diane von Furstenberg. The Jins Meme smart glasses launched by Japanese companies look like ordinary glasses, but they contain a lot of technology. The meme can even monitor your alertness so you don’t fall asleep while driving.

More and more technology companies will develop smart jewelry

Shortly after the rise of the wearable boom, there were a lot of crowdfunding projects on smart jewelry in the Indiegogo and Kickstarter platforms. Many projects point out that Mota SmartRing and Cuff have already achieved their financing goals, which means that female consumers may not be flustered by clunky smartwatches, but they really like the concept of smart jewelry.

Recently, Intel also entered the wearable market through its MICA smart bracelet. Its wearable device is equipped with excessive functionality and the outer skin and gemstone decoration of the snakeskin material.

Even they have not done so, and small manufacturers like Ringly, Mota, and Cuff will also push the smart jewelry market to grow further in the near future.

Your clothing will have more sensors built-in

There is no doubt that all, HexoSkin, and Sensoria will continue to introduce smart sweatshirts, sports underwear and other smart clothing, and more manufacturers will enter the field.

3D printed clothing has been released, and many famous fashion brands have symbolized Ralph Lauren’s polo and Victorian secrets, etc., which have already displayed their smart clothing in high profile. I have seen built-in LEDs, skirts that are discolored by the user’s mood, clothing made of fiber optics, and clothing that can detect air humidity before it rains.

Although these high-tech fashion clothes are a bit strange to consumers, they are the hallmark of the times. Smart clothing is booming, they will become easier and simpler in the future, and they hope they will become more useful at the same time.

You will know more about your body

Early sports wristbands did not accurately record the number of steps, but nowadays most high-end sports wristbands are moving in the direction of excellence. Many athletes participating in the Olympic Games and their coaches use sports wristbands to improve their performance. This is mainly due to the improvement of the algorithm, the perfection of the sensor and the addition of heart rate monitoring equipment.

In addition, the price of the low-end wristband will be cheaper, and even ordinary people can control their physical condition anytime and anywhere.

The models will show the wearable devices they actually wear

Ultimately, the target user of the wearable device is still a male consumer. Most wearables companies simply follow the women and show that their smartwatches are “free for men and women”. This is amazing! This kind of wearable device for men and women has never been a bestseller. However, this situation will change.

Nowadays, many crowdfunding wearable devices that focus on fashion will be sold online. Since Apple announced the Apple Watch, it has appeared in Paris Fashion Week, Fashion China and other fashion magazines.

Outstanding LG, Samsung, and Asus will certainly continue to push for more attractive wearables, and they may be launching one or two smartwatches for women.

In the future, through the gradual maturity and expansion of technologies such as AI / VR / AR, wearables will become an important representative of artificial intelligence.
