Explosion-proof secondary battery
An explosion-proof secondary battery includes a shell, an anode cap, a sealing ring, and a separating structure. The shell defines an opening on the top, and the shell comprises a crimping portion extending from the opening; the anode cap is disposed in the opening and latched with the crimping portion; the sealing ring is configured to seal a gap between the anode cap and the crimping portion; and a separating structure is disposed in the gap, and the separating structure resists the sealing ring; wherein the gap is remained when the sealing ring is melted, the anode cap is fixed to the shell by the crimping portion. In the explosion-proof secondary battery, due to the separating structure resisting the sealing ring, there is a gap between the anode cap and the periphery of the crimping portion of the shell, the internal gas of the explosion-proof secondary battery may successfully exhaust from the gap. Therefore, the internal air pressure of the explosion-proof secondary battery is decreased, and the separating structure prevents the explosion-proof secondary from exploding.
