Title:
ZN-AIR RECHARGEABLE BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/026068
Kind Code:
A3
Abstract:
The invention relates to a rechargeable Zn-air alkaline battery with air cathode and zinc anode, said alkaline battery comprising cellulose-based material as diaphragm. Said cellulose-based fabric is preferably woven or felted, preferably woven cotton diaphragm. The invention also relates to a rechargeable Zn-air alkaline battery with air cathode and zinc anode, said alkaline battery comprising carboxymethyl cellulose additive. Using cotton cloth as diaphragm 100 % Coulomb efficiency was detected during the entire measurement (more than 1000 cycles), while the weight of zinc electrode was constant and its surface remained smooth to solve the problem of dendrite formation.
