Why does the Wireless Power Bank bulge up

If the Lithium Power Bank is swollen, the reason is probably that the protection circuit of the motherboard is defective, and there is no over-discharge protection, which causes the battery to keep leaking. If the voltage is low and over-protected, the battery’s internal electrolyte and electrode materials will react. Gases such as hydrogen cause the battery to expand. The performance of the flexible polymer battery is more obvious.
