Factors affecting lithium batteries

Lithium batteries can generally be charged and discharged 300 to 500 times. It is best to partially discharge lithium batteries rather than fully discharge them, and to avoid frequent full discharge as much as possible. Once the battery is off the production line, the clock starts to move. Whether you use it or not, lithium batteries have a lifespan of only the first few years. The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main reason for the decrease in battery capacity). Finally, the resistance of the electrolytic cell will reach a certain point, and although the battery is fully charged at this time, the battery cannot release the stored electricity.
The aging rate of lithium batteries is determined by temperature and charging state. The following table illustrates the reduction in battery capacity for both parameters.
