In recent years, with the continuous progress of science and technology, ordinary lithium-ion batteries have been unable to meet the needs of people, especially in some special areas, lithium-ion batteries must be specialized, that is, special lithium-ion batteries.

Special lithium ion batteries are generally used in some special fields. Special lithium ion batteries must be customized. The difference between them and ordinary civilian batteries is that they have faster charging speed, wider operating temperature range, higher low-temperature discharge rate and better explosion-proof function.

Compared with civil lithium-ion batteries, special lithium-ion batteries have the advantages of wider operating temperature range, higher low-temperature discharge rate, faster charging speed and better explosion-proof function.

Low temperature battery: low temperature battery - 40 ℃ battery 0.2 discharge accounts for more than 80% of the rated capacity- 0.2 discharge of the battery accounts for the rated voltage at 50 ℃.

What are the advantages of special lithium-ion batteries compared with civil lithium-ion batteries?

1. Charging speed is faster. No matter the electrode material, diaphragm or electrolyte, the performance of special lithium-ion battery is better than that of ordinary lithium-ion battery, which is conducive to the migration of lithium ions and electrons. The charging speed of special lithium-ion battery is faster.

2. The operating temperature range is wider. The working range of ordinary lithium-ion battery is - 20 ℃ - 60 ℃, while that of special lithium-ion battery is about - 40 ℃, and 0.2C discharge can maintain more than 80% of the rated capacity.

3. The discharge rate at low temperature is higher. The moving speed of charged ions in ordinary lithium ion batteries at low temperature is slow and the resistance is large, so the discharge rate is low; The special lithium ion battery materials have excellent low temperature resistance, strong lithium ion diffusion ability and high discharge rate.

4. Better explosion-proof function. Compared with ordinary lithium-ion batteries, special lithium-ion battery materials have stronger stability and are suitable for some fields with harsh environment.
