What are the reasons for drums of drums?

　　1. Battery process

　　For example, the quality problem of the electrolyte itself, or the liquid level is not appropriate. Positive and negative electrode materials and production processes are rough, electrode coating is uneven or shell deformation. The second is that the pretending is not well closed or falls into the dust or has leakage.

　　2. Improper use

　　After the overcharge, the battery will cause gas formation pressure during the charging and discharge process. Generally, the internal pressure of the battery will not significantly increase, but if the charging current is too large, or the charging time is too long, the generated gas is too late to be. Consumption may cause an internal pressure, the battery deformation, leakage, and other adverse phenomena. At the same time, the life of its battery will also be affected.

　　3. Temperature effect

　　Temperature has the greatest effect on the battery's charging and discharge performance. If the temperature decreases, the reaction rate of the electrode also decreases. Assume that the battery voltage is kept constant, the discharge current is reduced, and the power output of the battery will decrease. The range of ambient temperature should be between 5 and 30. Generally, the charging efficiency will increase with the increase in temperature. The performance will degenerate, accelerate the risk of the battery's drum, and the cycle life of the lithium battery will also be greatly shortened.

　　4. The error storage method when not using the battery for a long time

　　The idle time is too long, and the battery does not need to occur for a long time, because the air is conductive to a certain extent. Therefore, it is equivalent to the positive and negative electrodes of the battery to direct contact and conduct chronic short circuits. If the spare battery is not used for a long time, it is recommended not to fill the electricity and save it. It is best to keep about 50 % of the electricity. It will be used for it every two months, which will greatly extend the service life of the battery.
