BATTERY, VEHICLE, AND EQUIPMENT USING BATTERY

摘要

A lithium secondary battery (100) is equipped with a non-recovering safety valve (117) comprising a valve (117e), which ruptures when the valve opens, and a valve perimeter (117f) that surrounds the valve (117e). The safety valve (117) is further disposed in the valve perimeter (117f), and has an anti-scattering means (117g) that prevents shards (117ex), which are produced by the valve (117e) rupturing when the valve opens, from scattering outside the battery. The anti-scattering means (117g) constitutes an anti-fragmentation part of a form that prevents shards (117ex) from fragmenting from the valve perimeter (117f).
