Abstract:
PURPOSE: Carbon materials for a super capacitor electrode and a manufacturing method thereof improve productivity by forming the carbon materials into the uniform shape and size. CONSTITUTION: Porous silica is manufactured (S100). A solution is dipped into the porous silica. Coal-tar pitch is dissolved in the solution. A carbon-silica composite is formed by carbonizing the coal-tar pitch (S300). Porous carbon is formed on the carbon-silicon composite (S400). [Reference numerals] (S100) Manufacture porous silica; (S200) Dip coal-tar pitch; (S210) Melt the coal-tar pitch; (S220) Coagulate the coal-tar pitch; (S300) Form a carbon-silica composite; (S400) Form porous carbon; (S500) Activate the porous carbon
