Embodiment Construction

[0036] The first object of the present invention is to provide a steel shell of an alkaline zinc-manganese battery. The structural design of the steel shell of the alkaline zinc-manganese battery can effectively solve the problem that the sealing part of the alkaline zinc-manganese battery is easy to explode. The present invention The second purpose of the invention is to provide a production process for the steel case of the alkaline zinc-manganese battery.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The invention discloses a steel shell of an alkaline zinc-manganese battery. The steel shell is characterized in that the wall thickness of the opening end of the steel shell is 0.34-0.37mm. The steel shell disclosed by the invention has the advantages that since the wall thickness of the opening end of the steel shell of the alkaline zinc-manganese battery is 0.34-0.37mm and is obviously increased compared with that of the opening end of the steel shell of the existing alkaline zinc-manganese battery, after the end part of the battery is sealed, the sealing strength is obviously improved, so that the stability of the produced alkaline zinc-manganese battery is improved, the anti-explosion capability of the opening end of the alkaline zinc-manganese battery is improved, and the safety of the alkaline zinc-manganese battery is improved. The invention also discloses a production process for producing the steel shell.

Description

technical field [0001] The invention relates to the technical field of batteries, and more specifically relates to a steel shell of an alkaline zinc-manganese battery and a production process thereof. Background technique [0002] The LR20 alkaline zinc-manganese battery mainly includes a steel case, a negative electrode collector and a sealing assembly inside the steel case. [0003] During the production of LR20 alkaline zinc-manganese batteries, after the negative electrode collector and sealing components are put into the steel case, it needs to be sealed. The sealing strength of the steel case determines the pressure resistance of the alkaline zinc-manganese battery. In reverse or short circuit safety test, it is required that the battery does not explode, that is to say, when the battery is used improperly, its internal negative electrode collector assembly will not pop out of the seal due to internal pressure. This requires that the pressure resistance capacity of th...
