Novel graphene ternary composite direct current-carrying plate

Abstract

A graphene ternary composite direct current-carrying plate includes an anode plate and a cathode plate. Placed between the anode plate and the cathode plate is a graphene composite layer. The graphene composite layer is doped with a certain proportion of graphene in the aluminum mesh frame. The plate of the invention has small thickness, low ohmic voltage drop, good porosity, and low current loss. This reduces the electrolysis power consumption, thereby significantly reducing the product cost and effectively promoting the industrial production market of the sodium chlorate electrolysis method. The plate also reduces energy consumption and is environmentally friendly.
