The IoT Battery Market to Grow Rapidly

Since everyday objects can now be connected to the internet, the IoT (Internet of Things) has now become a daily reality for many.  With the increased use of these IoTs, there has come a larger market for IoT batteries.

The new demands of connecting everything

In recent years, Amazon launched their AWS IoT, Microsoft their Azure IoT Suite, and many another tech Giants, like Xiaomi and Alibaba, their own platforms.  With these large companies promoting the technology and pouring in the necessary capital and resources, it is no wonder that the IoT battery market has seen demand and development.

Markets and Markets, an international market research agency,  said that the “global IoT market demand for batteries will reach $9.2 billion by 2020, and this figure is expected to increase to $15.9 billion by 2025, at a CAGR of 11.6% over the period." According to the agency, the key factors driving the rapid and steady growth of this market are the exponential growth in IoT usage, increased adoption of IoT devices, and increased global demand for wireless communications.
It is reported that current IoT batteries are mainly used in IoT appliances, such as car remote keys, smart door locks, smart medical devices, smart home appliances, and wearable devices. Unlike traditional electrical appliances, IoT appliances need to support the signal at any time in the rapid connection between devices and even need to support the signal transmission to the cloud.  In general, these types of IoT batteries require long life and high reliability, so lithium batteries are the main power source.

Markets and Markets note that the Asian-Pacific IoT battery market, including China, is expected to grow at an ultra-high CAGR in the future. Major manufacturers of wearable devices and consumer electronics are making their product designs miniaturized, and these products require miniature power supplies to be compatible with the designs.

What Factors Influence the Price of Lithium-ion Polymer Batteries?

The price of lithium-ion polymer (LiPo) batteries is mainly determined by their cell, PCM or PCB (Protection Circuit Module or Board), and casing.  The material used between cells, such as a conventional or formed nickel sheet and connectors also affects the cost of the batteries.

Battery selection

Different materials

The selection of cells of different chemical materials affects the price of the entire lithium battery. There are various materials such as lithium manganese (3.6V), lithium cobaltate (3.7V/3.8V), lithium nickel cobalt manganate (also called ternary, 3.6V), lithium iron phosphate (3.2V), lithium titanate (2.3V/2.4V), etc.

Different chemical materials have different voltage platforms, safety factors, cycle life, energy density, operating temperature, etc.

Different brands

The prices of different cells vary depending on the brand.  The price gradient can be divided into the following groups: special batteries (including low-temperature batteries, high-temperature batteries, high C-rate batteries, shaped batteries), Japanese batteries (Panasonic, Sanyo, Sony), Korean batteries (Samsung, LG), Chinese batteries (Piccolo, BYD, ATL, GREPOW).

Lithium battery’s PCM or PCB

The PCM design can be divided into three parts: basic protection, communication, and a BMS

Basic protection

There are basic protections against overcharge, over-discharge, overcurrent, and short-circuit protection, and even over-temperature protection can be added according to product requirements.

Communications

Communication protocols can be divided into I2C, RS485, RS232, CANBUS, HDQ, SMBUS, etc. There is also a simple battery LED indicator which indicates the charger meter.

BMS

The BMS is a battery management system that maintains each battery cell to prevent overcharging and over-discharging, extend battery life, and monitor the battery status. Its main functions include real-time monitoring of the battery’s physical parameters; battery status estimation; online diagnosis and warning; charge, discharge, and pre-charge control; and balanced management and thermal management. Subsystems are mostly used in electric vehicle batteries.

Designs of  Lithium battery cases

Lithium battery case designs can consist of PVC heat seal, plastic, or metal. The specific type of outer case of a battery depends on the specific needs of a customer’s product.

PVC Heat Seal

Heat-sealed PVC packaging of a battery pack can be generally used for battery packs that have an overall weight ≤ 2kg. For battery packs with an overall weight of ≥1kg, it is necessary to add a fixing bracket between the cells and then to use a PVC heat seal.

Plastic

The costs behind plastic casing can vary depending on the tools (tooling costs are a big expenditure), plate shell proofing (handmade strength is not as good as molded products), and materials used.

Metal

If a product has not been shaped before or the demand is not high, it is generally recommended to use sheet metal especially as the lead time can be shorter. The cost depends largely on the water-resistant rating for metal housings and even more so for special materials such as titanium alloy.

The price of Lithium-ion Polymer Batteries is mainly composed of the battery cell, PCM, and structural parts, plus the PACK cost, aging cost, and management cost of the enterprise. At the same time, due to the technical difficulty of the product, procurement volume, defective rate of different requirements, lithium battery prices will vary greatly.

Ternary Lithium Battery Classification

There are many kinds of anode materials for lithium-ion batteries. Depending on the cathode material, they can be divided into lithium cobaltate, lithium manganate, ternary materials, lithium iron phosphate, and lithium titanate.

A ternary lithium battery is a lithium battery that uses three metal oxides, nickel, cobalt, and manganese, as anode material. Since it combines the advantages of lithium cobaltate, lithium nickelate, and lithium manganate, the performance is superior to any of the above single anode materials. The experimental analysis indicates that the three different valence elements form a superlattice structure, and there are obvious synergistic effects between the three components, which makes the material more stable and the discharge platform is as high as 3.6V, so it is considered to be the most promising.

The current research on ternary materials mainly focuses on the preparation of precursors, the synthesis of materials, and the relationship between electrochemical properties and structure. Most of the transition metal elements Ni, Co, Mn exist in the +2, +3, +4. In the process of charging and discharging, the only electrochemical reactions are Ni2+/Ni4+ and Co3+/Co4+. Participation in the electrochemical reaction only serves to stabilize the structure of the material.

The commonly used synthesis methods in the industry include a high-temperature solid-phase, co-precipitation, sol-gel, hydrothermal synthesis, and combustion. By changing the molar ratio of the three materials in a ternary lithium battery within a certain range and adding the corresponding additives (binder, conductor, fluid collector, etc.), we can obtain outstanding performance and create batteries like the ultra-low temperature ternary lithium battery.

We will explore three ternary lithium batteries in this article.

Ternary polymer lithium battery’s electrolytes

A ternary polymer lithium battery refers to a lithium battery that uses a lithium metal cobalt lithium manganate (Li(NiCoMn)O2) ternary positive electrode material and a gel polymer electrolyte. As the transmission medium of ion motion, the electrolyte generally consists of a solvent and a lithium salt. The electrolyte of a lithium secondary battery mainly has a liquid electrolyte, an ionic liquid electrolyte, a solid polymer electrolyte, and a gel polymer electrolyte.

The gel polymer electrolyte is composed of a polymer, an organic solvent, and a lithium salt, and is obtained by mixing an organic electrolyte and a solid polymer matrix. Because it exists in a gel state, it has the advantages of both a solid electrolyte and a liquid electrolyte. Since the electrolyte is confined in the polymer chain, it has a high ionic conductivity over a wide temperature range. The biggest advantage is that the diaphragm is mechanically strong and the film provides a large surface area. The thinner the film, the higher the energy density as more active material can be embedded in the cell. In addition, the electrolyte has good electrochemical stability and high-temperature resistance; in fact, most high-temperature batteries on the market use polymer electrolytes.

Ternary power lithium battery

A ternary power lithium battery is a battery that supports high rate, high current discharge, high power density, and more energy being released per unit time. The rate discharge capability refers to the ability to maintain the battery capacity in the case where the charge and discharge rate is increased. The charge and discharge rate is expressed by C: 1C means that the nominal capacity of the battery can be used up in 1h, and the discharge at 2C can be used for 30min.

The power/rate performance of the battery is closely related to the design of the battery and is affected by many factors such as the electrolyte, diaphragm, type of active material, size of active particles, etc.

Among these factors, the thickness of the electrode is a major factor that affects the ability to have a large current discharge. The rate discharge capability can be greatly improved by thinning the electrode because thin electrodes have a small electronic impedance and ion impedance inside. However, thinning of the electrode results in less active mass in the electrode, and thus the battery capacity is reduced. Therefore, the main technical challenge of the ternary power lithium battery is to increase the large current discharge capability without reducing the capacity.

Ternary low–temperature lithium battery

The temperature characteristics of this battery are an indicator of battery reliability, and the performance of the battery can also be evaluated by changing the ambient temperature.

The low-temperature characteristics of lithium batteries mainly consist of low-temperature discharge characteristics and cycle life. Low-temperature batteries must maintain low-temperature conditions of material mobility so that lithium ions can freely pass between the positive and negative electrodes to achieve successful charge and discharge.

For example, using an electrolyte with a low melting point and reducing the particle size of the active material will enhance the low-temperature performance of the battery. This is due to the increased channeling of lithium ions, which, to some extent, compensates for the slow movement of lithium ions at low temperatures.

Ternary lithium batteries now

At present, ternary lithium battery manufacturers at home and abroad can basically achieve a discharge temperature of -20℃, a discharge capacity of more than 50%, and cycle life of about 400 cycles.  These can generally satisfy ordinary electrical appliances.

However, in special applications, such as aerospace, military equipment, or extreme cold environments, lithium batteries must be able to achieve lower discharge operating temperatures to meet demanding conditions. GREPOW has gathered a large number of electrochemical experts and engineers in the industry to successfully develop a low-temperature -40℃ discharge with a discharge capacity of 67%. It is mainly used for ultra-low temperature lithium batteries for military and special applications.
