Battery and battery protecting method

Abstract

The embodiment of the invention relates to the technical field of electronics and discloses a battery and a battery protecting method. The battery comprises a roll core, an aluminum shell and an anti-explosion protecting film, wherein a pressure relief hole is formed in the aluminum shell and is covered by the anti-explosion protecting film; and the anti-explosion protecting film and the aluminum shell are integrated to clad the roll core. According to the battery and the battery protecting method provided by the embodiment of the invention, the anti-explosion effect is achieved without increasing the complexity and implementation cost of a battery preparation process, so that the safety of the battery is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a battery and a battery protection method. Background technique [0002] With the popularity of electronic products, more and more batteries are used for electronic products. At present, batteries are basically divided into aluminum shell batteries and polymer batteries. Aluminum shell batteries are widely used because of their convenient disassembly, firm structure, high dimensional accuracy and relatively low cost. However, because the outer surface of the battery is a metal aluminum shell, once the battery cell Internal reactions, such as long-term high-rate charge and discharge, overcharge and discharge, impurities in the electrolyte during production, poor moisture control during the preparation process, and falling, etc. cause short circuits inside the battery core, which can easily cause battery bulges. However, due to its external structure It is an aluminum shell, s...
