Manufacturing method of activated carbon for electric double layer capacitor and the electric double layer capacitor electrode and the capacitor

摘要

The present invention relates to a method of water activated carbon prepared for use in the electrode of the electric double layer capacitor and hence of the electric double layer capacitor electrode as it relates to electrical double-layer capacitor using the oxidation step of oxidizing the carbon-water and attached to the carbon water the oxidized oxidation product alkali activation process activates at high temperature with alkali; Using the electrode and electrode using the electric double layer of activated carbon water producing method and the activated carbon water for capacitors made including; and alkali-activated active carbon water impurities removal step to minimize the other carbon component impurities by washing or heat treatment in which and the provision of an electric double layer capacitor as a technical base. Accordingly, to promote activation in the carbon-water was treated oxidizes carbon water by the alkaline component, with increase of the specific capacity of the active carbon with water or active carbon water electrode by forming an optimum fine-pore structure in the carbon-water, and this electric It has the effect of reducing the internal resistance of the double layer capacitor. ; An electric double layer capacitor graphitizing alkali activated carbon oxidized carbon softening
