Problems solved by technology

It can be mainly divided into two categories: the first category is the cover plate used for lithium iron phosphate batteries. Due to the better safety performance of lithium iron phosphate batteries, the traditional cover plate structure is less safe, and it is mainly used in lithium iron phosphate batteries.
The second type is the cover plate used for ternary material batteries. Due to the poor safety performance of ternary material batteries, the traditional cover plate structure is applied to ternary material batteries, and the safety of batteries is not high.

Abstract

The invention discloses a battery and a cover plate structure thereof. The cover plate structure comprises a cover plate (1), an anode pole structure, a cathode pole structure and a turnover sheet (3). One of the anode pole structure and the cathode pole structure is a first pole structure conducted with the cover plate (1), and the other pole structure is a second pole structure; the turnover sheet (3) can be turned over when the internal air pressures of the battery reach preset values; the second pole structure can be conducted with the cover plate (1) by the turnover sheet (3) in turnover states. The battery and the cover plate structure have the advantages that the cover plate structure comprises the turnover sheet, the battery can fail by means of blowout, accordingly, continuous increase of the internal air pressures of the battery can be prevented, and the service safety of the battery can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of battery structures, in particular to a battery and a cover plate structure thereof. Background technique [0002] At present, the cover plate structure of the battery is generally an aluminum cover plate structure, which is a precision component. It can be mainly divided into two categories: the first category is the cover plate used for lithium iron phosphate batteries. Due to the better safety performance of lithium iron phosphate batteries, the traditional cover plate structure is less safe and is mainly used in lithium iron phosphate batteries. The second type is the cover plate used for ternary material cells. Due to the poor safety performance of ternary material cells, the traditional cover plate structure is applied to ternary material batteries, and the battery is not safe to use. [0003] Therefore, how to improve the use safety of the battery is an urgent problem to be solved by those skilled ...
