1. An electrode of an energy storage device comprises:

a polymer derived ceramic coal dust composite electrode layer, wherein the polymer derived ceramic coal dust composite electrode layer is formed from a source of coal dust, the source of coal dust being coal dust, by mixing the source of coal dust with a silicon oxy carbide resin to form a mixture, the mixture being processed by pyrolysis causing a chemical reaction between the source of coal dust and the silicon oxy carbide resin, wherein the source of coal dust and the silicon oxy carbide resin is converted to a porous ceramic that is electrically conductive.
