Lithium-ion battery ternary lithium-ion battery related knowledge introduction

August 1, 2023

Lithium-ion Ternary Battery (Lithium-ion Ternary Battery), also known as lithium-ion ternary battery, is a lithium-ion battery using ternary positive electrode materials. It is one of the most widely used lithium-ion battery types.

1. Structural composition: The ternary lithium-ion battery consists of three main components:

Cathode material: Commonly used ternary battery cathode materials are formed from compounds of nickel, cobalt and manganese, such as lithium nickel cobalt manganese oxide (LiNiCoMnO2 or NMC).

Negative electrode material: The negative electrode material is usually graphite, which is used to intercalate lithium and release lithium ions.

Electrolyte: The electrolyte is the conductive medium between the positive and negative electrodes in the battery, usually composed of organic solvents and lithium salts.

2. Advantages:

High energy density: The ternary lithium-ion battery has a high energy density, which can provide relatively high energy storage, thereby prolonging the working time of the battery.

High charge and discharge efficiency: The ternary battery has high charge and discharge efficiency, can provide high output power, and has less loss during cycle use.

Long cycle life: Compared with other lithium-ion batteries, ternary batteries usually have a longer cycle life and can perform more charge and discharge cycles.

3. Application fields:

Electric vehicles: Ternary lithium-ion batteries are widely used in electric vehicles, because of their high energy density and long cycle life, they can provide reliable and long-lasting driving capabilities.

Mobile devices: Ternary batteries are also widely used in mobile devices such as mobile phones, tablet computers and notebook computers. Because of their high energy density and small size, the devices can have long-lasting and stable battery life.

Energy storage system: Since ternary batteries have high energy density and long cycle life, they can be used in energy storage systems, such as home energy storage systems, solar and wind energy storage systems, etc.
