The optimal level of operating temperature for #lithiumbatteries is 0 to 35℃. The low-temperature environment will reduce the activity of lithium ions, the lipo battery discharge capacity will be weak, and the use time will be shortened. If the lithium battery using in a low-temperature environment for a short period of time, the damage is only temporary and does not damage the battery capacity. The performance will recover when reinforcing the temperature.
However, if the battery is charged and discharged in a low-temperature environment for a long time, metal lithium will be separated out on the surface of the “battery anode”. This process is irreversible and permanently damage to the battery capacity. Like sometimes, at low temperatures, our smartphone will automatically shut down. It is for the purpose of protecting the battery, on the other side, it is also caused by the unqualified and aging of the self-battery.
