Lithium battery with protection function

Abstract

The invention provides a lithium battery with a protection function, and relates to the technical field of lithium batteries, and the lithium battery comprises a box body, and a lithium battery body is fixedly installed in the box body; the plurality of protection boxes are fixedly mounted on two sides of the lithium battery body; the fixed box is fixedly mounted at the top of the lithium battery body; the top of the fixed box protrudes out of the upper surface of the box body; and the heat dissipation assembly is arranged in the box body and is used for cooling and dissipating heat of the lithium battery body. According to the lithium battery, through cooperative use of the box body, the protection box and the protection assembly, the capability of resisting external impact force can be improved, meanwhile, when the lithium battery is subjected to strong impact, the direction of the impact force can be changed, and the influence of the impact force on the lithium battery body is reduced; the lithium battery can be powered off when being impacted or under the condition that the temperature in the box body is too high, explosion and spontaneous combustion of the lithium battery are prevented, and the service life of the lithium battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery with a protective function. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical properties 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. [0003] In the production process of lithium batteries, in order to protect the lithium battery, the lithium battery is generally prevented from being inside the protective box or protective shell to prevent the lithium battery from being exposed to the air, which is easily affected by external environmental factors. Damage occurs, affecting the service life of the lithium battery. [0004] T...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the background technology and provide a lithium battery with a protective function. Through the cooperation of the box body, the protective box and the protective component, the ability to resist external impact can be improved, and at the same time, it can withstand strong impact. When the impact force is used, the direction of the impact force can be changed to reduce the impact of the impact force on the lithium battery body. Through the combined use of the fixed box and the power-off component, the lithium battery can be repaired while being impacted or when the temperature inside the box is too high. Power-off processing to prevent explosion and spontaneous combustion of lithium batteries and prolong the service life of lithium batteries
