Lithium ion batteries are widely used in electric vehicles, aircraft models, stabilizers and other equipment due to their high energy density, long cycle life, moderate manufacturing cost and low environmental pollution. What are the five factors that affect the life of lithium batteries?
Lithium ion batteries are widely used in electric vehicles, aircraft models, stabilizers and other equipment due to their high energy density, long cycle life, moderate manufacturing cost and low environmental pollution. What are the five factors that affect the life of lithium batteries?
1、 High and low ambient temperature
Lithium batteries should not be used in harsh environments because they are afraid of cold and heat. The migration rate of lithium ion in electrolyte and electrode plate is closely related to temperature. Overheating or undercooling will affect its movement rate. In practical application, the operating temperature of lithium battery is between 5 ° C and 35 ° C. Therefore, for northern households, lithium batteries should be taken back to their homes for storage as much as possible in winter, and should not be placed outdoors. For southern users, they should avoid exposure to the sun in summer.
2、 Charging time
Many young friends like to recharge the battery for another hour after it is fully charged, because they think that the longer the charging time is, the more full the battery will be. In fact, this method may reduce the life of lithium batteries, and even cause safety accidents in serious cases! Correct practice: unplug the power supply immediately after charging!
3、 Discharge time
Nowadays, many young people, in order to play games, often wait until there is only one or two bars of electricity left on their mobile phones, or even no electricity, and then charge them. This will do great harm to the battery. The lithium battery has no memory function, so it can be charged when the accumulated discharged power exceeds 80-90% of the battery capacity. It does not need to be recharged after deep discharge.
4、 Whether the charger matches
The matching charger is also very important. The use of an inferior brand charger or an unsuitable fast charger will not only affect the service life of the lithium battery itself, but also cause an explosion due to the damage and short circuit of the diaphragm caused by overheating.
5、 Storage method
For lithium battery products that are not used for a long time, the voltage should be about 3.7V and the power should be between 40% and 60%. In this range, the performance of lithium battery is relatively stable.
