Lithium-Ion Battery Maintenance And Storage Tips Sharing

A lithium-ion battery is a secondary battery (rechargeable battery) that relies primarily on the movement of lithium ions between 

the positive and negative electrodes to work. During the charge and discharge process, Li+ intercalates and deintercalates back and 

forth between the two electrodes: during charging, Li+ is deintercalated from the positive electrode and embedded in the negative 

electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true. Batteries 

generally use materials containing lithium as electrodes and are representatives of modern high-performance batteries. So how should 

lithium-ion batteries be maintained and stored in daily life? 

The following will be explained to you by the technical staff of 

Asialand, a lithium battery casing manufacturer:

1. 

Lithium-ion batteries have very low self-discharge and can generally be stored for 3 years. The effect will be better if stored under 

refrigerated conditions. It is a good idea to store lithium-ion batteries in a cold place.

2. 

Lithium-ion batteries can be stored for more than half a year at 20°C. This is because its self-discharge rate is very low and most of its 

capacity can be restored. Lithium-ion batteries have self-discharge phenomenon. If the battery voltage is stored below 3.6V for a long time, 

it will cause the battery to over-discharge and damage the internal structure of the battery, reducing the battery life.

3. 

Lithium-ion batteries stored for a long time should be recharged every 3 to 6 months, that is, it is appropriate to charge to a voltage of 

3.8 to 3.9V (the optimal storage voltage of lithium batteries is about 3.85V) and not to be fully charged. Lithium-ion batteries have a wide 

application temperature range. They can still be used outdoors in winter in the north, but the capacity will be reduced a lot. If they return 

to room temperature, the capacity can be restored, subject to a certain temperature impact.
