Performance explanation of low temperature battery

Because of its advantages of light weight, high specific energy and long life, lithium batteries are widely used. Low-temperature lithium batteries are made of special materials and processes. They are suitable for cold environments and have good discharge capacity and working performance, generally at 40°C. Working in a high-quality environment, the discharge capacity is maintained above 80%, and the minimum operating temperature can reach 50°C. According to its use environment, it is divided into three series of civilian low-temperature batteries, special low-temperature batteries and extreme environment low-temperature batteries. Household low-temperature lithium battery: -20℃0.2℃ discharge accounts for more than 90% of the rated capacity; -30℃ battery 0.2c discharge accounts for more than 85% of the rated capacity; special low-temperature lithium battery: -40℃ battery 0.2c discharge accounts for 80% of the rated capacity % Or more; extreme environment low-temperature lithium battery: at -50℃, the 0.2c discharge of the battery accounts for more than 50% of the rated capacity. The full name of polymer battery is lithium polymer battery. This is a lithium battery. From the perspective of battery cells, lithium batteries are divided into first-generation steel-shell lithium batteries, second-generation aluminum-shell lithium batteries, and third-generation polymer lithium batteries. Because of the polymer battery encapsulation and aluminum composite film, this film is only 0.3 meters thick, and the internal space of the reactive material is the largest. The aluminum composite film is lighter than the steel shell, and the aluminum composite film can stop, effectively reducing battery adverse reactions. The pressure to prevent the possibility of explosion. The polymer lithium battery is the battery with the largest capacity, the lightest weight and the best safety among the lithium batteries.
