Abstract
A method of making a carbon-metal oxide composite electrode for a supercapacitor includes continuously injecting a carbon material solution into a coagulation solution, where the carbon material solution comprises a carbon source and a liquid, and the coagulation solution comprises a metal nitrate or chloride and an organic solvent. An extruded structure comprising the metal nitrate or chloride interspersed with carbon is formed from the continuous injection. The extruded structure is annealed under conditions sufficient to convert the metal nitrate or chloride to metal oxide. Thus, a composite structure comprising the metal oxide and the carbon is formed, where the metal oxide is uniformly dispersed within the composite structure.
