AI Technical Summary
Technical Problem
Copper-aluminum composite poles are prone to breakage at the interface, leading to reduced product reliability and shortened service life.
Method used
A battery cover is designed by creating a terminal mounting groove on the cover body, placing terminal limiting parts of different materials in the groove, and applying extrusion force between the limiting parts by compressing insulating and sealing components to change the direction of the force and enhance the bonding force.
Benefits of technology
This improved the tightness of the electrode mating surface, reduced the probability of breakage, enhanced product reliability, and extended service life.

Abstract
This utility model belongs to the field of battery technology and discloses a battery cover and a battery. The battery cover includes a cover body, a first insulating element, a sealing element, and a first and a second electrode post made of different materials. The first electrode post includes a first insertion part and a first limiting part, and the second electrode post includes a second insertion part and a second limiting part. A mating surface is formed between the first and second limiting parts. The cover body has a first electrode post through hole, a second electrode post through hole, and an electrode post mounting groove that are interconnected. The first and second limiting parts are both located in the electrode post mounting groove. A compressed first insulating element is provided in the gap between the first limiting part and the electrode post mounting groove along a first direction, and a compressed sealing element is provided in the gap between the second limiting part and the electrode post mounting groove along the first direction. This changes the original pulling force on the mating surface into a compressing force on the mating surface, reducing the probability of breakage at the mating surface, improving product reliability, and extending service life.
