Abstract

The invention provides a filling type battery exhaust device which comprises a shell. A prefabricated hole is formed in the shell, a prefabricated fragment is arranged in the prefabricated hole, the prefabricated fragment is detachably and fixedly connected with the inner wall of the prefabricated hole, and the strength of a connecting structure between the prefabricated fragment and the shell is smaller than structure strength of the shell; a filler is arranged between the prefabricated fragment and the inner wall of the prefabricated hole, the filler surrounds the prefabricated fragment, the filler is fixedly connected with the prefabricated fragment and the inner wall of the prefabricated hole, and the structural strength of the filler is smaller than the structure strength of the shell; and when the internal pressure of the battery is too high, the prefabricated fragment falls off from the shell firstly so that the shell is decompressed, and the shell is prevented from exploding.

Description

technical field [0001] The present application relates to the technical field of battery protection, in particular to a filled battery 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 a filled battery exhaust device, which is used to ...
