the higher the storage temperature and battery charge and the more full, more severe loss of its capacity. So I do not recommend long-term preservation of lithium-ion batteries, the batteries if the hands are idle, then the stored charge level should not exceed 40%, the best temperature lower than 15 ? or less. The nickel-metal hydride battery cell is almost free from aging effects of long-term storage of nickel-based batteries charge during the deep discharge after a few deep can be restored to its original capacity of the. But deep charge deep discharge can not be restored the capacity of lithium-ion battery and will cause permanent damage to the positive and negative. From the molecular level, the excessive discharge of carbon anode will lead to excessive release of lithium ions, causing structural collapse of its layers, too many will over-charging lithium ion hard to go into negative carbon structure, and makes some lithium-ion can no longer be released. Second, lithium-ion battery charging process Lithium-ion battery charging from the pre-charge stage, the constant current charging and constant voltage charging phase of stage three parts, shown in Figure 1. That is slowly filling pre-charge stage, when the battery voltage falls below a certain voltage value Zeyi 0.1C (C is battery capacity) low current charge, so long in a discharged state and the reduction of passive film dissolution, and also to prevent the battery from the depths of the beam into the fast charge discharge status caused by battery overheating stage constant current charging phase to the fast charge constant current charging 1 C, the sustained, rapid charge battery voltage limit is reached; constant voltage to constant voltage charging stage of charging, the charging current will fall to the end stage of pre-set current value.
