1. What is a ternary lithium battery?
A ternary lithium battery is a lithium-ion battery that uses lithium nickel cobalt manganese oxide as the positive electrode, graphite as the negative electrode, and a liquid electrolyte as the electrolyte. It is known for its high energy density, long cycle life and excellent safety performance, and is widely used in electric vehicles, energy storage systems and other fields.
2. What is the working principle of ternary lithium battery?
The working principle of ternary lithium batteries is to store and release charges through the migration of lithium ions between the positive and negative electrodes. During the charging process, lithium ions migrate from the negative electrode (graphite) to the positive electrode (lithium nickel cobalt manganese oxide); during the discharging process, the opposite is true. This process is accomplished through ion conduction in the electrolyte.
3. What is the cathode material of ternary lithium battery?
The positive electrode material of ternary lithium battery is lithium nickel cobalt manganese oxide (LiNiCoMnO2), also known as NCM material. It has high capacity, high energy density and good cycle stability, and is one of the most widely used positive electrode materials for lithium batteries.
4. What is the negative electrode material of the ternary lithium battery?
The negative electrode material of the ternary lithium battery is generally graphite, which has good conductivity and stability, and can realize the embedding and de-embedding of lithium ions, thereby realizing the charging and discharging process of the battery.
5. What is the electrolyte of ternary lithium battery?
The electrolyte of ternary lithium batteries generally uses organic solvents, such as carbonates, polymer electrolytes, etc. The main function of the electrolyte is to provide a channel for ion transmission, allowing lithium ions to migrate between the positive and negative electrodes.
6. How does the charging and discharging process of a ternary lithium battery work?
During the charging process, the external power supply provides current, causing lithium ions to migrate from the negative electrode to the positive electrode, and the nickel, cobalt, and manganese oxides in the positive electrode material (NCM) are gradually oxidized, and the battery stores electrical energy. During the discharge process, the load extracts current, causing lithium ions to migrate from the positive electrode to the negative electrode, and the positive electrode material is gradually reduced, releasing the stored electrical energy.
7. What is the cycle life of a ternary lithium battery?
Ternary lithium batteries have a long service life and can withstand thousands of charge and discharge cycles without loss of performance. Its specific life depends on factors such as the use environment and the charging and discharging method.
8. How safe are ternary lithium batteries?
Ternary lithium batteries have high safety performance and use a stable material combination to reduce safety risks. However, there may still be safety hazards in extreme cases, such as overcharging, over-discharging, and high temperature, which may cause battery overheating, fire, and other safety issues.
