What causes a lithium ion battery to fail?

Overheating is one of the main causes of lithium-ion battery failures, although physical damage to the battery can also lead to problems. Excessive heat — for example from using a faulty charger and overcharging the battery, or due to a short circuit — can damage the battery cell internally and cause it to fail.

Are lithium ion batteries safe?

Lithium-ion batteries are generally safe when used and maintained correctly. However, they can pose risks under certain conditions, such as: Overcharging: Overcharging a lithium-ion battery can lead to thermal runaway, a chain reaction that causes the battery to overheat and potentially catch fire or explode.

Are lithium-ion batteries a problem?
