What are the advantages and disadvantages of the ternary lithium battery?lithium battery for solar energy storage system

　　1. The ternary lithium battery is a type of lithium battery: it mainly refers to the positive electrode material of the battery, and the positive pole material of the lithium battery is usually lithium cobaltate.

　　2. Lithium batteries that use nickel cobalt manganate as orthopedic materials are commonly known as lithium battery of ternary materials. It is priced cheaper than lithium cobaltate, slightly higher to resist, and the average voltage is slightly lower (the battery industry is called a battery platform) capacity. A little bit higher, but the compaction is lower, and the battery capacity of the same model is slightly lower than the lithium cobaltate battery.

　　3. The biggest feature of the ternary lithium battery is that the unit power is relatively large, which is the result of the lithium iron phosphate battery.

　　4. But a large disadvantage of a ternary lithium battery is that the fire point is low when it is impacted and high temperature. Therefore, the protection of ternary lithium batteries is high to prevent accidents.

　　The ternary lithium battery is relatively balanced in terms of capacity and safety, and is a battery with excellent comprehensive performance. The main functions and advantages of the three metal elements are as follows:

　　CO3+: Reduce the mixing of cations, stabilize the layer -shaped structure of the material, reduce the resistance value, improve the conductivity, and improve the circulation and efficiency performance.

　　NI2+: It can increase the capacity of the material (increase the volume energy density of the material). Due to the similar radius of Li and Ni, too much NI will also be mixed with lithium nickel due to incorrect phenomena with li. The larger, the more difficult to embed lithium in the layered structure, resulting in poor electrochemical performance.

　　MN4+: It can not only reduce the cost of material, but also improve the safety and stability of the material. However, too high MN contents will easily occur with spinel phases and destroy the layered structure, reduce the capacity, and circulate attenuation.

　　High energy density is the biggest advantage of the ternary lithium battery, and the voltage platform is an important indicator of battery energy density. It determines the basic performance and cost of the battery. The higher the voltage platform, the larger the capacity. The battery of ASTS has a longer battery life with a higher voltage platform.

　　The single ternary lithium battery discharge voltage platform is as high as 3.7V, and the lithium iron phosphate is 3.2V, while the lithium titanate is only 2.3V. Therefore, from the perspective of energy density, the three -yuan lithium battery has an absolute advantage.
