리튬 이온 배터리가 자체 방전되는 이유와 자체 방전을 측정하는 방법은 무엇입니까? Posted by batterymanufactory.com
The self-discharge reaction of lithium-ion batteries is inevitable, and its existence not only leads to the reduction of the battery's own capacity, but also seriously affects the battery's configuration and cycle life. The self-discharge rate of lithium-ion batteries is generally 2% to 5% per month, which can fully meet the requirements for the use of single batteries. However, once a single lithium battery is assembled into a module, because the characteristics of each single lithium battery are not completely the same, after each charge and discharge, the terminal voltage of each single lithium battery cannot be completely consistent, which will cause problems in the lithium battery. The performance of the single lithium battery will be deteriorated if there is an overcharged or overdischarged single battery in the module. As the number of charging and discharging increases, the degree of deterioration will be further aggravated, and the cycle life will be ...
