Lithium-ion batteries suffer severe energy loss when operating at temperatures below zero degrees Celsius, limiting the use of electrical equipment in snowy weather and high altitudes.
In order to improve the low-temperature performance of lithium-ion batteries, the following two methods are currently used:
1) Add additives to improve the low temperature performance of the electrolyte;
2) External heating and insulation of the battery.
Developed a lithium iron phosphate battery that can work normally at minus 30 degrees, breaking the vacancy in the market in one fell swoop. It is worth mentioning that this minus 30 degrees is different from most low-temperature batteries (customizable) products on the market. Low-temperature batteries It's a real low temperature.
Recommended lithium batteries that can be used at minus 40°C>>
Through the use of proprietary electrolyte formula and other special functional raw materials, coupled with leading innovative technologies, the battery can still be discharged efficiently at extremely low temperatures, and the discharge capacity at -20°C at 0.2C exceeds the initial capacity. 90%, 95% at -30°C. The working temperature is -40℃~55℃. Coupled with the high cycle life of the lithium iron phosphate battery itself, it solves the problems of many equipment manufacturers in one fell swoop.
Low temperature lithium battery characteristics ：
1. Using superposition technology, low internal resistance;
2. -40℃ 0.2C discharge, the discharge capacity exceeds 90% of the initial capacity;
3. -50℃ 0.2C discharge, the discharge capacity exceeds 75% of the initial capacity;
4. Wide working temperature range, -40°C to 55°C;
5. Can be charged at -40°C;
6. Lithium iron phosphate chemical substance is used, which has high safety and long cycle life;
