4. Charging
4.2. Influence of temperature
Low temperatures
- Charging Li-ion at temperatures below 5°C with limited current only, in frost is not allowed.
- Fast charging in the range of 5 - 45 ° C, but preferably 10 - 30 ° C.
- Charging in the cold damages the battery ("plating" the anode with lithium, permanent, irreversible changes).
High temperatures
- High temperatures are harmful for any type of battery.
- Usually, they cannot be charged at T> 50 ° C, it accelerates aging.
- Current limitation is necessary, charging with high current at high temperature reduces the capacity of the battery.
- May cause gas production and inflation.
