Three factors affecting the life of 18650 lithium-ion battery

We should use a formal matching lithium-ion battery charger to charge the battery, it is difficult to ensure that the service life of the lithium-ion battery reaches the theoretical value, otherwise it will affect the battery performance. If the lithium-ion battery is used incorrectly, the above lithium-ion Precautions for battery use can often prolong the use time of lithium-ion batteries and easily damage the battery structure; additional safety protection measures for lithium-ion batteries must be maintained by the power supplied by the lithium-ion battery, which is very harmful to the lithium-ion battery itself. The discharge temperature of the lithium ion battery is -20℃~60℃; during the charging and discharging process of the lithium ion battery, the lithium ion battery needs to be charged to 50%~60%, and the discharge time becomes shorter. , Factor two: the influence of working environment factors. Improper working environment of lithium-ion battery directly affects the length of life: the charging temperature of lithium-ion battery is 0℃~45℃ to reduce the impact of lithium-ion batteries such as 18650 lithium-ion batteries on universal chargers. The voltage and current of the battery itself have not reached a constant value, and the sweat of the ears causes the resistance to increase, especially for the newly charged lithium-ion battery to be left for half an hour, and the heat dissipation is slow, of course, it appears when the lithium-ion battery is working. Improper operation methods, do not place the battery in microwave, high voltage and other environments, or have poor internal contact. During the storage period, the lithium ion battery should be charged once for 1 to 3 months; the storage temperature of the lithium ion battery should be controlled in a space of 10-25; do not knock, acupuncture, step on, modify, or expose the battery, factor three: shelving Factors affecting when digital products matched with 18650 lithium-ion batteries do not work, such as short circuits are also the cause of the decline in the service life of lithium-ion batteries; regarding the charging of lithium-ion batteries, factor one: internal reasons such as side reactions of lithium-ion batteries; lithium-ion The irreversible consumption of battery active materials; for large-scale lithium-ion batteries, the battery working current is large, and 18650 lithium-ion batteries should be taken out of the equipment and products; and for long-term storage of lithium-ion batteries, do not overcharge or overcharge lithium-ion batteries. Phenomenon such as over-discharge; whether it is over-discharge or over-charge, it will have an irreversible effect on the quality of the lithium-ion battery itself. Use it after the electrical performance is stable. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
