Oxide nanotube composite carbon-based electrode material and preparation method thereof

Abstract

The invention relates to an oxide nanometer pipe composite carbon base electrode material of super capacitor and it's preparing method. Wherein the electrode material comprises following components: the metal oxide nanometer pipe in 0.1-20 mass%, the conductive carbon black in 0.1-15 mass%, the nanometer metal in 0.1-8 mass%, the activated carbon in 0.1-99 mass%, and the nanometer activated carbon fiber in 0.1-99 mass%. Based on the activated carbon with high rate of surface area and the nanometer activated carbon fiber, said electrode material utilizes the metal oxide nanometer pipe and three-dimensional network cage construction formed by said metal oxide nanometer pipe to supply the transmission channel of hydronium of electrolyte, which can markedly improve the effective rate of surface area of electrode activated material to improve the capacity density of said electrode material, to attain the super capacitor with high energy density. And The invention has lower cost and supports the commercial application.
