Battery structure, battery and preparation method thereof

Abstract

The invention provides a battery structure, the battery structure includes: circuit elements, including a first contact piece and a second contact piece arranged along a first direction; a transfer piece; and a turn-out piece; wherein: the transfer piece includes: The first transfer section is coupled with the first contact piece; and the second transfer section extends from the first transfer section along a second direction, and the second direction is perpendicular to the first direction; the turning-out piece includes: a first turning section an out section coupled with the second contact piece; a second pivot out section connected with the first pivot out section; and a third pivot out section extending from the second pivot out section. The present invention also provides a battery and a preparation method thereof. The purpose of the present invention is to provide a battery structure, a battery and a preparation method thereof, so as to at least reduce the risk of breakage of circuit breaker pins in the switching process, and simplify the switching process at the same time.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery structure, a battery including the battery structure, and a preparation method thereof. Background technique [0002] Thermal cutoff (TCO for short) can sense the overheating generated during abnormal operation of electronic products, thereby cutting off the circuit to avoid fire. In battery products, in-situ TCO structures are often used for thermal protection. [0003] In the in-situ TCO transfer process, the in-situ TCO must be pasted and positioned on the top seal of the cell before the next action can be performed. At this time, the transfer sheet and the transfer sheet are overlapped above the first tab. The welding of the first tab and the adapter piece cannot be achieved, and the swivel-out piece needs to be lifted before welding; The whole process is completed only when it is pressed down in parallel with the top seal of the cell. [0004] It can be seen tha...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the entire transfer process is not only complicated, but also that the transfer sheet is lifted and pressed, and there is a stress perpendicular to the main body of the cell at the bend, which causes the transfer sheet to warp and is regarded as a defective product; When the output piece is bent back and forth, it will drive the pins of the circuit breaker to be stressed, which will increase the risk of breakage and failure of the pins of the circuit breaker
