Lithium battery cover plate structure

Abstract

The invention discloses a lithium battery cover plate structure and relates to the technical field of a lithium battery cover plate. The structure comprises a cover plate, wherein a lower surface of the cover plate is fixedly connected with a lower insulating pad, bolt holes are formed in corners of an upper surface of the cover plate, one end of the upper surface of the cover plate is fixedly connected with a positive electrode mounting base, the other end of the upper surface of the cover plate is fixedly connected with a negative electrode mounting base, fixing bases are connected into thepositive electrode mounting base and the negative electrode mounting base in an embedded mode correspondingly, mounting base insulating pads are connected into the fixing bases in an embedded mode correspondingly, and a profiling through opening is formed in the middle of the upper surface of the cover plate. The lithium battery cover plate structure is advantaged in that connection between the cover plate and the lower insulating pad is more stable, the cover plate and the lower insulating pad are fixed in a clamping manner, and through a valve, a profiling storage groove can be shielded, theinternal space of the profiling storage groove can be separated, and dust can be prevented from entering the lithium battery through the profiling storage groove.

Description

technical field [0001] The invention relates to the technical field of lithium battery cover plates, in particular to a lithium battery cover plate structure. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical characteristics of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The batteries are placed in a A battery pack is formed inside the box, and a cover plate is set on the battery pack to close it, and electrical conduction is realized through the electrical component...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the present invention provides a lithium battery cover structure, which solves the problem that the existing lithium battery cover has a single structure and poor practicability, and an insulating pad is usually arranged between the electrode components of the lithium battery cover. The firmness between the existing cover plate and the insulating pad is poor, and when the existing insulating pad is in use, the friction between the insulating pad and the electrode mounting seat is small, and the insulating pad is prone to deflection or even falls off during use However, the existing lithium battery cover is usually connected by bolts, and the fixing method is single. After a long time of use, the bolts are easy to loosen, causing the cover to shake or even fall off. At the same time, the pressure relief port of the existing cover is in the When in use, it is easy to rotate, resulting in the problem of easy accumulation of dust inside the pressure relief port
