How to improve the service life of lithium batteries

Lithium batteries can generally be charged and discharged 300-500 times. It is best to discharge the lithium battery partially rather than completely, and beware of frequent and complete discharges as much as possible. Once the battery is off the processing line, the clock starts to move. Regardless of whether you use it or not, the service life of lithium batteries is only in the first few years. The decrease in battery capacity is due to the increase in internal resistance caused by oxidation (this is an important reason for the decrease in battery capacity). Eventually, the resistance of the electrolyzer will reach a certain point. Although the battery is overflowing at this time, the battery cannot release the stored power. The aging speed of lithium batteries is determined by temperature and charging conditions. The following table illustrates the decrease of battery capacity under two parameters. Temperature charging 40% charging 100% 0°C capacity after one year 98% capacity after one year 94% capacity after 25°C one year capacity 96% capacity after one year 80% capacity 40°C after one year capacity 85% capacity after one year It can be seen that the capacity of 65% at 60°C is 75% after one year and the capacity is 60% after three months. It can be seen that the high charging situation and new temperature have accelerated the decline of battery capacity. If possible, try to charge the battery to 40% and store it in a cool place. This enables the battery's own protection circuit to operate during a long storage period. If the battery is exposed to high temperature after overflowing, it will cause great damage to the battery. (So u200bu200bwhen we use a fixed power supply, the battery is fully charged at the moment, and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to drop).
