What is the self-discharge of the secondary battery? What is the self-discharge rate of different types of batteries?
Self-discharge, also known as charge retention, refers to the ability of the battery to store electricity under certain environmental conditions in an open state. In general, self-discharge is primarily affected by manufacturing processes, materials, and storage conditions. Self-discharge is one of the main parameters for measuring battery performance. In general, the lower the battery storage temperature, the lower the self-discharge rate, but it should also be noted that if the temperature is too low or too high, the battery may be damaged and cannot be used.
After the battery is fully charged and left on for a period of time, a certain degree of self-discharge is normal. The IEC standard stipulates that the nickel-hydrogen battery is fully charged and has an open circuit for 28 days at a temperature of 20 ° C ± 5 ° C and a humidity of (65 ± 20) %. The 0.2 C discharge capacity reaches 60% of the initial capacity.
