- a chargeable / dischargeable sealed secondary battery has a high energy density, so when an internal short circuit or external short circuit occurs, or when abnormal heating or abnormal shock occurs, a rapid charge / discharge reaction or chemical reaction occurs inside the battery. A sudden gas generation occurs due to the reaction, which may cause the battery case to expand or even rupture. Therefore, many sealed secondary batteries are provided with a safety valve (explosion-proof mechanism) that exhausts gas generated in the battery to the outside when the pressure in the battery reaches a predetermined value.
