Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the current lithium battery either lacks a protection device, or because the explosion-proof diaphragm of the protection device is broken by the high-pressure gas inside the battery, although the inside of the battery can be released by air pressure, it is necessary to replace the explosion-proof membrane. Very troublesome and costly problems, and a lithium battery proposed

Abstract

The invention discloses a lithium battery, and belongs to the technical field of lithium batteries. The lithium battery comprises a lithium battery body and further comprises an anti-explosion mechanism and a sphere mechanism, wherein the sphere mechanism is installed on the anti-explosion mechanism, and the anti-explosion mechanism is installed on the lithium battery body; when the lithium battery body generates abnormal gas and the internal pressure of the battery body is too large, U-shaped plates on the two sides move upwards to extrude a second spring, one supporting leg of each U-shaped plate extrudes the inclined face of a second movable plate, the second movable plate extrudes a first spring to make an arc-shaped plate enter an arc-shaped hole, the U-shaped plate continuously moves upwards, and a fifth movable plate moves into a first square hole under the action of a fourth spring, so that an inner cavity of the lithium battery is communicated with a first through hole, a second through hole, a third through hole, a through hole and an air outlet hole, and is communicated with the outside, abnormal gas is discharged, and lithium battery faults and even explosion are avoided.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a lithium battery. Background technique [0002] Lithium-ion batteries are the power storage components of lithium batteries. When they are in use, due to factors such as charger failure and overcharging, abnormal gases will be generated along with the internal chemical reactions of the battery, resulting in excessive internal pressure of the battery, resulting in battery failure. Explosion accidents, at this stage, the lithium battery either lacks a protective device, or because the explosion-proof diaphragm of the protective device is broken by the high-pressure gas inside the battery, although the internal pressure of the battery can be released, the explosion-proof membrane needs to be replaced, which is very troublesome and higher cost. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the current lithium batter...
