Abstract

The invention provides an integrated battery directional exhaust device which comprises a shell. A prefabricated fragment is integrally connected to the shell, the prefabricated fragment and the side wall of the shell are located on the same plane, and the inner space of the shell is defined by the shell and the prefabricated fragment. The strength of a connecting structure between the prefabricated fragment and the shell is smaller than structure strength of the shell; a prefabricated groove is formed in the surface of the shell and surrounds the prefabricated fragment, and the depth of the prefabricated groove is smaller than the wall thickness of the shell; when the internal air pressure of the shell is increased to exceed the bearable limit of the prefabricated fragment, the prefabricated fragment is firstly broken or fall off from the shell, and an exhaust port is formed in the shell so that the internal pressure of the shell is conveniently relieved, a smoke and fire gas is conveniently exhausted, the shell is prevented from exploding due to overlarge internal pressure intensity, and the integrity of the shell is further ensured; and therefore, external air cannot fully enter, and fire is prevented from expanding and spreading.

Description

technical field [0001] The present application relates to the technical field of battery protection, in particular to an integrated battery directional exhaust device. Background technique [0002] Batteries in the prior art usually include a casing, a cathode, an anode, an electrolyte and an electrolyte. The cathode and the anode are inserted in the electrolyte, and the electrolyte is dissolved in the electrolyte. The difference in redox properties between the cathode and the anode in the electrolyte is used to A directional charge flow is generated, forming an electric current. During the charging and discharging process of the battery, chemical reactions occur continuously inside, generating heat, accompanied by a part of gas generation. When the battery is in a sealed state and the gas volume is large, excessive internal pressure may easily cause the shell to explode. Contents of the invention [0003] The present application provides an integrated battery directional...
