POSITIVE ELECTRODE FOR ELECTRIC DOUBLE LAYER CAPACITOR AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To improve characteristics of energy density of an electric double layer capacitor and charge-and-discharge rate etc. thereof, and to provide a positive electrode for the electric double layer capacitor useful therefor, and a simple manufacturing method thereof. SOLUTION: The positive electrode for the electric double layer capacitor contains graphite-carbon composite particles each composed of a graphite particle and a carbon layer covering the graphite particle.
