GAS-EXHAUSTING APPARATUS, BATTERY CELL, BATTERY AND ELECTRICITY-CONSUMING APPARATUS

Abstract

A gas-exhausting apparatus, a battery cell, a battery and an electricity-consuming apparatus are provided by the present application. The gas-exhausting apparatus includes a gas-exhausting body and a gas-exhausting mechanism. The gas-exhausting mechanism includes a connecting assembly and a gas-ventilating member. The connecting assembly includes a first connecting member and a second connecting member. The first connecting member is provided with a first through hole for communicating with an inside of the battery cell. The second connecting member is provided with a second through hole for communicating with an outside of the battery cell. The first connecting member is configured to attach to a surface of the gas-ventilating member facing the inside of the battery cell. The second connecting member is configured to attach to a surface of the gas-ventilating member facing away from the inside of the battery cell. An orthographic projection of the first through hole on the gas-ventilating member and an orthographic projection of the second through hole on the gas-ventilating member are arranged to be staggered from each other. The present application can alleviate the aging and damage of the gas-ventilating member caused by an electrolyte adhering to the gas-ventilating member, and improve the overall reliability of the gas-exhausting apparatus.
