Problems solved by technology

[0002] The defect of the existing lithium battery is that it is easy to expand and damage, or even explode. There are many reasons for the explosion of the lithium battery, such as large internal polarization, and the reaction between the electrode piece absorbing water and the electrolyte changes, etc. It will be accompanied by volume expansion, and during the expansion process, the internal current will increase rapidly, and the volume will change rapidly. It is difficult for people to react immediately, so it is easy to be hurt

Abstract

The invention discloses a lithium battery expansion explosion protection device based on an electromagnetic induction principle. The device comprises: a box body, wherein the upper surface of the box body is provided with a box cover; a battery mounting seat, wherein a lithium battery fixing rod is mounted in the battery mounting seat; and a heat dissipation mechanism mounted at the bottom in the box body, and connected with the battery mounting seat. According to the lithium battery expansion explosion protection device based on the electromagnetic induction principle, the box cover is opened, an expanded lithium battery is placed on the battery mounting seat, and the box cover is closed, at the moment, the heat dissipation mechanism works to cool the lithium battery in the box body, the explosion effect of the lithium battery is reduced, the explosion of the lithium battery is sealed in the box body, and the harm of explosion to people is reduced.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery expansion and explosion protection device based on the principle of electromagnetic induction. Background technique [0002] The defect of the existing lithium battery is that it is easy to expand and damage, or even explode. There are many reasons for the explosion of the lithium battery, such as large internal polarization, and the reaction between the electrode piece absorbing water and the electrolyte changes, etc. It will be accompanied by volume expansion, and during the expansion process, the internal current will increase rapidly, and the volume will change rapidly. It is difficult for people to respond immediately, so they are vulnerable to injury. Contents of the invention [0003] In order to achieve the above purpose, the present invention discloses a lithium battery expansion and explosion protection device based on the principle of elec...
