Classification of low-temperature lithium batteries

　　1. According to discharge performance, it can be divided into energy storage low-temperature lithium batteries and multiple low-temperature lithium batteries. Low temperature energy storage lithium batteries are widely used in military tablets, paratrooper equipment, military navigators, drone reserve power supply, special navigation instrument power supply, satellite signal receiving equipment, ocean data monitoring equipment, atmospheric data monitoring equipment, outdoor video recognition equipment, oil exploration and detection equipment, railway monitoring equipment, outdoor power grid monitoring equipment, military thermal shoes, and vehicle backup power supply. Low temperature multiple lithium batteries are used in infrared laser equipment, strong light armed police equipment, and acoustic armed police equipment.

　　2. According to the application field, it can be divided into military low-temperature lithium batteries and industrial low-temperature lithium batteries.

　　3. According to the low-temperature usage environment, it can be divided into -20 ℃ civilian low-temperature lithium batteries, -40 ℃ special low-temperature lithium batteries, and -50 ℃ extreme environment low-temperature lithium batteries.

　　4. Divided by their usage environment: civilian low-temperature batteries, special low-temperature batteries, and extreme environment low-temperature batteries.

　　(1) Civilian lithium batteries: -20 ℃ batteries with 0.2C discharge account for more than 80% of the rated capacity- The 0.2C discharge of a 30 ℃ battery accounts for more than 50% of the rated capacity;

　　(2) Special low-temperature lithium battery: -40 ℃ battery with 0.2C discharge accounts for more than 80% of the rated capacity- The 0.2C discharge of a 50 ℃ battery accounts for more than 30% of the rated capacity;

　　(3) Extreme low-temperature lithium battery: The battery occupies more than 50% of its rated capacity at 0.2C and -50 ℃.
