Storage method of lithium battery

Lithium battery is a kind of battery with lithium metal or lithium alloy as positive/negative electrode material and using non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, preservation and use of lithium metal require very high environmental requirements. Below, take a look at Hongli Energy lithium battery manufacturers together.

1. Lithium galvanic battery

Also known as primary lithium battery. It can be discharged continuously or intermittently. Once the power is exhausted, it can no longer be used, which is widely used in cameras and other electronic products with low power consumption. Lithium galvanic battery self-discharge is very low, can be stored as long as 3 years, in cold storage conditions, the effect will be better. It is a good idea to store lithium galvanic batteries at a low temperature. Note: Lithium galvanic battery is different from lithium ion battery, lithium galvanic battery can not be charged, charging is very dangerous!

2. Lithium-ion batteries

Also known as secondary lithium battery. It can be stored at 20℃ for more than half a year, which is due to its low self-discharge rate, and most of the capacity can be recovered.

Self-discharge exists in lithium batteries. If the battery voltage is kept below 3.6V for a long time, the battery overdischarge will damage the internal structure of the battery and reduce the battery life. Therefore, the long-term storage of lithium batteries should be charged once every 3 to 6 months, that is, the charging voltage is 3.8~3.9V (the best storage voltage of lithium batteries is about 3.85V), keep at 40%-60% discharge depth is appropriate, not full. Batteries must be stored in a dry environment of 4 ° C to 35 ° C or packed with moisture proof. Keep away from heat and out of direct sunlight.
