Lithium battery with high sealing and flame retardance

Abstract

The invention discloses a lithium battery with high sealing flame retardance, and belongs to the field of lithium battery application. The lithium battery with high sealing flame retardance comprises a lithium battery pack and a battery box, wherein the lithium battery pack is installed in the battery box, a heat dissipation partition plate is arranged on the inner wall of the battery box, a top plate is fixedly connected to the top end of the battery box, a second sliding groove is formed in the top plate, and a temperature sensing air bag is arranged in the second sliding groove. Compared with the prior art, the lithium battery of the invention has the advantages that when the battery is overheated, the temperature sensing air bag is expanded, and the heat dissipation fan is started to dissipate heat of the lithium battery, so that the lithium battery is prevented from being overheated and exploded; when the battery is at a normal temperature, the heat dissipation ventilation pipe is disconnected, the air outlet is closed, the heat dissipation pipe is protected, dust accumulation is prevented, and the service life is prolonged; and when the battery is damaged, an internal electrolytic solution leaks and internal combustion occurs, the electrolytic solution burns through the heat dissipation partition plate, at the moment, a flame retardant embedded in the heat dissipation partition plate leaks and diffuses in the battery box, the internal temperature is reduced, and the flame-retardant effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of lithium battery applications, and in particular relates to a lithium battery with high sealing and flame retardancy. Background technique [0002] In the application process of lithium batteries, the ignition and burning of lithium batteries has always been the key problem to be solved. However, most of the reasons for the ignition and burning of existing lithium batteries are that the battery is overcharged, the charging time is too long, and the battery has not been unplugged after charging. The charger is always charged and connected to the battery, excessive use of the battery, heavy load for a long time, excessive discharge of the battery, the battery will heat up, and the danger of explosion will occur when overheating, that is, a sealed lithium battery with high flame resistance is needed to solve the above problems . Contents of the invention [0003] The object of the present invention is to p...
