Abstract
The utility model provides a lithium battery combined cover plate, which comprises a cover plate and an explosion-proof valve hermetically welded at an opening of the cover plate. An explosion-proof valve pore is used as a liquid injection hole for a lithium battery. The combined cover plate further comprises an anti-rotation support, a positive pole, a negative pole, an upper sealing ring, a lower sealing ring and locking nuts, wherein the negative pole and the positive pole penetrate through openings of the anti-rotation support, the lower sealing ring, an upper cover plate and the upper sealing ring to be fastened via the locking nuts. When the combined cover plate is used on the lithium battery, the combined cover plate and a battery casing are sealed and fixed by using laser welding. By using the sealing means of injecting electrolyte through the explosion-proof valve pore for the lithium battery, the combined cover plate has the advantages of simple structure, convenience and speediness, convenient injection and capability of achieving the effect of convenient sealing.
