The bulging of lithium batteries may be caused by the following reasons: 1. Overcharging causes the lithium battery to bulge. Overcharging will cause all the lithium ions in the positive electrode material to run into the negative electrode material, causing the original full grid of the positive electrode to deform and collapse. In this process, the negative electrode has more and more lithium ions. Excessive accumulation causes the lithium atoms to grow stumps and crystallize, causing the battery to swell. This is also one of the main reasons for the decline in the power of lithium battery packs. 2. The bulging SEI film caused by over-discharge will have a protective effect on […]
