A man chewed on a mobile battery at a convenience store, causing it to explode. As per The Sun, the battery exploded immediately and the fire was contained before spreading. As of publishing, the exact location in India has not been confirmed.Lithium-ion battery failures are rare, however in the event of a malfunction, they can cause a serious fire risk. When a lithium-ion battery is damaged or short-circuited, it can heat up quickly triggering a thermal runaway, where chemical reactions inside the battery produce heat and flammable gas. If the gas isn’t released safely, the battery can catch fire, burst, or explode.
