Claims

[Scope of utility model registration request]

(1) A metal sealing lid with a through hole in the center, an elastic body made of rubber or the like that closes the through hole, and pressurizing the elastic body while maintaining a gap between the flange and the metal sealing lid. A battery comprising a welded metal cap, an explosion-proof device having a metal rod-shaped current collector welded to the inside of the through hole with a gap between the metal sealing lid and the rod-shaped current collector.

(2) The gap between the metal sealing lid and the metal rod-shaped current collector is such that the top of the rod-shaped current collector is provided with one or a radial groove passing through a position facing the through hole of the sealing lid, and the non-grooved portion of the top is sealed. A battery comprising a rod-shaped current collector and the explosion-proof device according to claim 1, which is formed by welding to the inner surface of the lid.

(3) The gap between the metal sealing lid and the metal rod-shaped collector is provided with a plurality of protrusions on the surface of the top of the rod-shaped collector that does not face the through hole of the sealing lid, and the protrusions are welded to the inner surface of the metal sealing lid. A battery comprising an explosion-proof device and a rod-shaped current collector according to claim 1 of the utility model registration claim.

(4) The gap between the metal sealing lid and the metal bar-shaped current collector includes one or a radial groove passing through a position facing the through-hole of the sealing lid at the top of the rod-shaped current collector, and a groove facing the through-hole. Explosion-proof device and rod-shaped collector according to claim 1, which is obtained by providing a plurality of protrusions in a portion that is not a groove and welding the protrusions to the inner surface of a metal sealing lid. and a battery.
