Aqueous zinc ion battery and preparation and application of modified zinc negative electrode of aqueous zinc ion battery

Abstract

The invention belongs to the field of water-based zinc ion batteries, and particularly relates to a water-based zinc ion battery and preparation and application of a modified zinc negative electrode of the water-based zinc ion battery, and the modified zinc negative electrode comprises a zinc substrate and a modified coating compounded on the surface of the zinc substrate; the modified coating comprises a binder and a modifier # imgabs0 # shown in the formula A. The surface of the zinc substrate is innovatively coated with the functional coating with the structure shown in the formula A, and the functional coating has excellent stability and high zinc ion conduction rate and can also show excellent stability under high discharge depth and large current density.
