ZINC ELECTRODE FOR ALKALINE NICKEL-ZINC BATTERY AND PREPARATION METHOD THEREFOR

Abstract

Disclosed is a preparation method for a zinc electrode, including: a step of dissolving a water-soluble calcium salt of organic acid in deionized water to obtain a first mixed solution; a step of preparing a negative electrode slurry by mixing the first mixed solution, a water-soluble binder, a thickener, and an active material including zinc oxide; and a step of preparing the zinc electrode by applying the slurry to a surface of a current collector and baking it at a high temperature. Further disclosed is a zinc electrode prepared by the preparation method, and use of the zinc electrode in an alkaline nickel-zinc battery. The zinc electrode prepared in the present disclosure can not only effectively improve the deformation thereof and solve the growth problem of zinc dendrites, but also contribute to increasing the utilization rate of an active material of the zinc electrode and improving the cycle performance of the alkaline nickel-zinc battery.
