Title:
GAS EXHAUSTING DEVICE, BATTERY CELL, BATTERY, AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/077466
Kind Code:
A1
Abstract:
Provided in the present application are a gas exhausting device, a battery cell, a battery and an electric device. The gas exhausting device comprises a gas exhausting body, a first gas-permeable piece and a second gas-permeable piece; the first gas-permeable piece is arranged on the gas exhausting body; the second gas-permeable piece is arranged on the gas exhausting body, and is located on the side of the first gas-permeable piece in the thickness direction of the gas exhausting body; the first gas-permeable piece and the second gas-permeable piece are used for allowing a gas to pass through when the gas pressure in a battery cell reaches a first threshold value. The gas exhausting device provided by the present application helps to reduce the risk of the leakage of electrolytes in the battery cells, and to ensure the normal pressure relief work of the battery cells, thereby helping to improve the safety performance of the battery cells.
