Title:
GAS ADSORBENT, SECONDARY BATTERY AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/233264
Kind Code:
A1
Abstract:
The present application belongs to the technical field of batteries, and more specifically relates to a gas adsorbent, a secondary battery and a device. The gas adsorbent comprises a cuprous ion compound and a porous material. The gas adsorbent has both a high specific surface area and chemical properties of a complex reaction with CO, and can timely reduce the internal pressure caused by gas generated from the interaction between pole pieces of the cell and the electrolyte, reduce the swelling and interface impedance of the cell, and extend the life of the battery. The gas adsorbent is encapsulated by using a porous gas-permeable thin film and disposed inside the cell. The structure is simple and easy for industrial production and manufacturing.
