Five major factors affecting the life of lithium battery

Lithium-ion batteries are widely used in electric vehicles, model aircraft, stabilizer and other equipment because of their advantages of high energy density, long cycle life, moderate manufacturing cost and small pollution to the ecological environment. What are the five major factors that affect the life of lithium batteries?

1. Ambient temperature level

Lithium battery is not afraid of cold but also afraid of heat, so we should try not to use it in a harsh environment. The migration rate of lithium ions in the electrolyte and the electrode sheet is closely related to the temperature, and both overheating or overcooling can affect its movement rate. In practice, the operating temperature of the lithium battery is between 5℃ and 35℃. Therefore, the northern users, winter as far as possible to retrieve the lithium battery home storage, do not put outdoors, the southern users to avoid summer exposure.

2. Lengof charging time

Many people like to continue to charge the battery for another hour as a "supplement", because they think that the longer the charge time, the fuller the battery power. In fact, this method may cause the life of lithium battery reduced, serious will also cause safety accidents! Correct approach: you should unplug the power supply immediately after charging!

3. Lengof discharge time

Now there are a lot of young people in order to play games, often wait until the mobile phone is only one or two grids of electricity, or even out of electricity, and then take to charge, so that the damage to the battery is very big. Lithium battery has no memory function, so when the cumulative power discharged more than 80-90% of the battery capacity can charge, do not have to do a deep discharge before charging.

4. Does the charger match

A matching charger is also very important. The use of mixed-label charger or unadapted fast charger not only affects the service life of the lithium battery itself, but also explodes due to the damaged short circuit of the diaphragm caused by overheating.

5. Storage method

Long-term unused lithium battery products, the voltage should be guaranteed at about 3.7V, and the power quantity is maintained at between 40% and 60%. In this range, the performance of lithium battery is relatively stable.
