6 FAQs about [Lithium battery shrunken]

What happens if a lithium ion battery is damaged?

The cathode electrode determines the potential of the lithium-ion battery. Damage to the cathode material leads to a slightly lower battery potential upon full recharge after impact and causes partial capacity loss of the lithium-ion battery. 3.3.
