Abstract
The present invention discloses a cover plate for a lithium ion battery. The cover plate includes a cover body and a sealing piece. The cover body is provided with an infusion hole. At least part of the sealing piece is located inside the infusion hole and fitted tightly with the infusion hole for sealing it. The sealing piece has a flange, which extends outside the infusion hole and limits depth of the sealing piece into the infusion hole. The present invention also discloses a battery case and a lithium ion battery provided with the above-mentioned battery cover plate. The present invention has the following beneficial technical effect: With the flange provided on the sealing piece, it is easy to control depth of the sealing piece into the infusion hole during punching and sealing, thus avoiding a bad sealing problem in the prior packaging technology resulted from punching too shallow or too deep.
