Lithium-ion ternary battery refers to a battery that uses lithium ions as charge transfer. Its main material is composed of three elements, usually nickel (Nickel), cobalt (Cobalt) and manganese (Manganese), so it is called It is three yuan.
Compared with lithium batteries, ternary batteries have some differences in battery performance and characteristics:
- Capacity and energy density: Compared with traditional lithium batteries, ternary batteries have higher capacity and energy density, that is, unit volume or unit Mass can store more electrical energy. This means that ternary batteries can provide longer driving range and are suitable for high energy consumption applications.
- Safety: Since ternary batteries use relatively less cobalt, compared with some lithium batteries, ternary batteries are better in terms of safety. Cobalt is a material prone to thermal runaway and oxidation. Excessively high temperatures may cause cobalt to pyrolyze in the battery, which may further cause the battery to overheat, cause fire or even explode. The use of ternary combination materials, especially reducing the cobalt content, helps improve the safety performance of batteries.
- Cycle life: Compared with lithium batteries, ternary batteries have better cycle life and smaller capacity attenuation. Cycle life is the number of times a battery can be used continuously during charge and discharge cycles, while capacity fading refers to the gradual loss of energy storage capacity of the battery during use. The design and materials of the ternary battery can reduce capacity fading, allowing the battery to maintain high performance over long-term use.
It should be noted that there are still many different chemical combinations and technical configurations between different lithium batteries and ternary batteries. Therefore, different battery types may have other differences in characteristics and suitability for specific applications. When purchasing batteries, you need to consider factors such as capacity, energy density, safety, and cycle life to select the most suitable battery type and specifications based on your needs.
