Abstract:
A case body (21), a battery (20), and an apparatus (100). The case body (21) is provided with a discharge hole (215) used to discharge flames generated in the interior of the case body (21) when a battery cell (22) experiences a thermal runaway. The case body (21) is further provided with a fire extinguishing member (23) used to extinguish the flames passing through the discharge hole (215) and perform cooling. In the invention, a discharge hole (215) and a fire extinguishing member (23) are arranged on a case body (21), such that the fire extinguishing member (23) can release a fire extinguishing agent to extinguish flames passing through the discharge hole (215) generated when a battery cell (22) experiences a thermal runaway and perform cooling, thereby preventing the flames from being discharged from the interior of the case body (21) via the discharge hole (215), and improving safety performance of a battery (20).
