Title:

NEGATIVE ELECTRODE AND ZINC SECONDARY BATTERY

Document Type and Number:

WIPO Patent Application WO/2022/118610

Kind Code:

A1

Abstract:

Provided is a negative electrode with which it is possible to improve durability by suppressing deterioration of the negative electrode caused by repetition of charging and discharging, thereby extending cycle lifetime thereof. This negative electrode is for use in a zinc secondary battery, and includes a nonionic water-absorbing polymer and a negative electrode active material containing ZnO particles and Zn particles. The nonionic water-absorbing polymer is contained in an amount of 0.01-6.0 parts by weight, as a solid, with respect to 100 parts by weight of the ZnO particles.
