Be careful of lithium-ion battery fires!
About Lithium-Ion Batteries
Fires caused by lithium-ion batteries in smartphones, tablets, mobile batteries, and other devices are increasing. In the year 2024, there have been three fires caused by lithium-ion batteries.
[Fire Incident Example]
A "bang" sound was heard from a mobile battery charging on a futon, and upon checking, a flame about 1 meter high was found rising from the charging mobile battery.
As a result of the investigation, it is believed that the lithium-ion battery internally short-circuited, causing it to heat up, expand, rupture, and catch fire.
