Under the condition of the environment temperature 25℃, the characteristic curve about various discharging rate of unit cell is:
Usually use constant voltage limited current charge after battery discharging, the charging voltage is 2.35V/unit(25℃), charging current is≤0.15C10A. The curve about charging current and charging time is:
a. Use multi-element alloy for battery, and special electrolyte additive, store 1 month at normal temperature, self-discharging ＜3﹪.
Self-discharging is associated with storage temperature. When the temperature is low, the self-discharging is low, and when the temperature is high, the self-discharging is high.
After a period of storage, unit cell can obtain the surplus capacity approximately though the open-circuit voltage. The relationship between voltage and surplus capacity is:
The curve of capacity and temperature:
Discharging capacity value of different discharging rate of battery will slowly increase when temperature increases. The curve is：
