Lithium batteries cannot be charged at low temperatures. The electrolyte used in lithium batteries is an organic liquid, like grease, which becomes viscous or even condenses at low temperatures. At present, the activity of the conductive lithium salt indoors is significantly limited. In this case, the charging efficiency is very low, which will cause the lithium battery to charge slowly at low temperature and incomplete charging, and the same is true. for discharge.
The same goes for lithium polymer batteries. At least one of the positive and negative electrodes and the electrolyte of lithium polymer batteries use polymer materials, and the electrolyte may use solid or colloidal polymer electrolytes. Therefore, low temperature environments also impact lithium polymer batteries.
Detailed information:
Although the normal operating temperature rating of many mobile power supplies is relatively wide, but as the temperature decreases, the discharge performance of lithium batteries decreases significantly , the discharge platform decreases significantly, and the discharge capacity decreases significantly.
When the temperature drops to -30℃, the battery discharge capacity is 87.0% of the discharge capacity at room temperature, the average discharge voltage is 0.598V lower than that at room temperature and the stored energy is only that of ordinary environment. About 70%. The constant current charging capacity of lithium-ion batteries is only 14% of the total charging capacity, and the constant voltage charging time will become very long.
It is actually very simple to avoid the effects of low temperatures. When the ambient temperature is low, tryPlease avoid using mobile power under exposure conditions. If you must use it, try to save it. temperature above zero degrees Celsius. After using it for a while, the heat of the mobile power itself will gradually make it work normally.
