摘要： A battery cover includes a cover body, a mounting opening is formed in the cover body, an explosion-proof valve is mounted in the mounting opening, at least one bursting line is arranged on at least one surface of the explosion-proof valve, the explosion-proof valve is provided with a first injection molding surface located on an outer side of the bursting line, and a plastic layer obtained by injection molding is arranged on the first injection molding surface and a second injection molding surface of the mounting opening. In the battery cover of the present application, an existing connecting and fixing process based on laser welding in the industry is replaced, avoiding negative influences caused by a high temperature during the laser welding process, realizing a stable explosion-proof value, and increasing the yield and reducing the manufacturing cost.

摘要： An electrode post for a battery cover, includes an upper substate and a lower substrate. An upper connection surface for contacting with an external component is arranged on one side of the upper substrate, an extension board is arranged on the other side of the upper substrate, a groove for receiving a sealing element and a fastener is formed in a side wall of the extension board; and the lower substrate is arranged at a tail end of the extension board, a lower connection surface for contacting with an inner component of a battery is arranged on a side, opposite to the extension board, of the lower substrate. The connection strength of the electrode post and the battery cover is increased and the structural strength and sealing performance of a final battery product is increased, thus improving the reliability and prolonging the service life of the final battery product.
