High-capacity lithium battery capable of avoiding piercing short circuit

Abstract

The invention provides a high-capacity lithium battery capable of avoiding piercing short circuit, relates to the technical field of lithium batteries, and aims to solve the problems that an existing high-capacity lithium battery is easy to be impacted or pierced during use, so that the lithium battery is easy to be short-circuited, and the lithium battery cannot be automatically stressed to buffer impact force when being impacted or falling off, and after long-time use, high temperature is easy to occur, and heat dissipation effect is relatively poor. The battery comprises a main body, a pressing groove, a pressing rod and a fixing piece, and the main body is of a rectangular structure, and the interior of the main body is of a rectangular structure; the pressing groove is formed in the middle of the two sides of the top end of the body, and side grooves in the two ends of the pressing groove are formed in the two sides of the top end in the body; and the pressing rod is installed in the pressing groove through a spring at the bottom. The moving part is used for being mounted in the main body, so that the lithium battery can be directly fixed in the moving part through the mounting plate, and the moving part can protect the lithium battery and prevent the lithium battery from being punctured.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and more specifically relates to a large-capacity lithium battery that avoids puncture short circuits. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. [0003] For example, the application number: CN201710110132.3 relates to a lithium battery, including a battery cell and a casing, the battery cell is arranged in the casing, and the battery cell includes a positive electrode sheet, a negative electrode sheet, and a diaphragm, and is characterized in that the positive electrode sheet, the negative electrode sheet and the diaphragm A thin-film temperature sensor is arranged between them. The thickness of the thin film temperature sensor can reach several microns. The research of combining heat-sensitive materials with thin film molding has m...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a large-capacity lithium battery that avoids puncture short circuit, so as to solve the problem that the existing large-capacity lithium battery is easy to encounter impact or puncture during use, which easily leads to short circuit of the lithium battery. , and in the event of an impact or drop, it cannot automatically bear the force to buffer the impact force, and it is prone to high temperature after long-term use, and the heat dissipation effect is poor, and when the existing large-capacity lithium battery is used, it will When performing protection, if the lithium battery is small in size, it is prone to vacancy and shaking, and it is easy to make the lithium battery unstable during use, and it is impossible to adjust and fix the lithium battery conveniently.
