In theory, lithium batteries should not be charged in environments with temperatures below 0°C. Although there may not be immediate consequences in the short term, lithium metal can still precipitate on the surface of the anode, and this process is irreversible. Therefore, repeated charging at low temperatures can cause damage to the battery, reducing its safety, especially when subjected to external pressure, impacts, etc.
To avoid this phenomenon, the only solution is to avoid using lithium batteries at extremely low temperatures and minimize their usage time in low-temperature environments.
Alternatively, specialized low-temperature lithium batteries specifically designed for low-temperature environments can be used.
Low-temperature lithium batteries operate within a low-temperature range of -40°C to 55°C. Low-temperature lithium batteries are a special type of battery developed to overcome the inherent low-temperature performance limitations of chemical power sources. Our low-temperature batteries utilize innovative design concepts, proprietary formulations and materials, and rigorous manufacturing processes to overcome many technological barriers and develop a series of low-temperature lithium batteries.
