AI Technical Summary

Technical Problem

Existing battery cover protection solutions are difficult to provide stable and effective protection, cannot resist external environmental interference, and have insufficient insulation performance, which affects the safety and lifespan of the battery.

Method used

The battery adopts a double-layer insulating sheet structure. The first insulating sheet is attached to the battery cover plate, and the second insulating sheet covers the first insulating sheet. The whole protection is formed by the annular protrusion and the insulating film. The insulating sheet is provided with a break area and information hole to ensure the insulation and protection effect.

Benefits of technology

The battery cover achieves double insulation, protecting the safety valve, reducing the risk of edge warping, ensuring the battery's insulation performance and safety, and facilitating information display and polarity marking.

Abstract

This application relates to the field of battery technology, specifically to a battery. The battery includes a first insulating sheet and a second insulating sheet. The first insulating sheet is attached to a battery cover plate and has a first terminal opening corresponding to a through-hole for a terminal post. The size of the first insulating sheet is smaller than the size of the battery cover plate. A second insulating sheet is attached to the first insulating sheet and has a second terminal opening corresponding to a through-hole for a terminal post. In application, the first and second insulating sheets are sequentially attached to the battery cover plate. The first insulating sheet, being smaller than the battery cover plate, prevents edge warping and loss of insulation protection. The second insulating sheet, covering the first insulating sheet, provides double insulation and protection.
