Performance analysis of low-temperature lithium-ion batteries

Low-temperature high-rate lithium-ion batteries can be used as ordinary low-temperature lithium-ion batteries, of course, the price is definitely different. Under low temperature environment, it supports 3C～5C rate discharge for 3～5 seconds, and pulse discharge can reach about 55C. High-rate low-temperature lithium-ion batteries have the basic performance of ordinary low-temperature polymer lithium-ion batteries; normal discharge performance of low-temperature lithium-ion batteries: 1. High low-temperature discharge performance, with a minimum discharge rate of 0.2c at -40°C, with an efficiency of more than 65%; Under the environment of 30℃, discharge at 0.2c, the discharge capacity is 85%; 2. Wide operating temperature range, -50C to 50C; 3. Excellent low temperature cycle performance, charge and discharge at 0.5c at -30℃, 300 cycles The rear capacity remains above 85%; 4. The safety performance is high, and it has passed UL/CE/UN certification; 5. The size is flexible, and can be customized according to the size and shape of the customer; 6. It has the ability to batch processing and the battery is consistent Good performance; 7. Large current can appear at -40°C and maintain large capacity; 8. Under -40°C working environment, it can still maintain its excellent performance; because the temperature range of day and night in low temperature areas in China is mostly -30°C ~38℃, and the temperature in a small part of the area is around -45℃. Therefore, the low-temperature lithium-ion battery in these areas should meet the temperature range of -35℃～65℃.
