What are the five major 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 major factors that affect the life of lithium batteries?
1. Ambient temperature
Lithium batteries are afraid of cold and heat, so try not to use them in harsh environments. The migration rate of lithium ions in the electrolyte and electrode sheet is closely related to temperature, and overheating or overcooling will affect its movement rate. In practical applications, the operating temperature of lithium batteries is between 5°C and 35°C. Therefore, users in the north should take the lithium battery home and store it at home in winter as much as possible, and do not put it outdoors. Users in the south should avoid exposure to the sun in summer.
2. The length of charging time
Many friends like to continue to charge the battery for another hour as a "supplement" after the battery is fully charged, because they think that the longer the charging time, the fuller the battery power. In fact, this method may reduce the life of lithium batteries, and even cause safety accidents in severe cases! The correct way: unplug the power immediately after charging!
3. The length of discharge time
In order to play games nowadays, many young people often wait until the mobile phone has only one or two batteries left, or even no power, before charging it, which will cause great damage to the battery. Since the lithium battery has no memory function, it can be charged when the discharged electricity exceeds 80-90% of the battery capacity, and it is not necessary to recharge after deep discharge.
4. Whether the charger matches
A matching charger is also very important. Using a brand-name 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 short circuit damage to the diaphragm due to overheating.
5. Storage method
For lithium battery products that are not used for a long time, the voltage should be around 3.7V, and the power should be maintained between 40% and 60%. In this range, the performance of lithium batteries is relatively stable.
