Title:
中孔質炭素材料、炭素/金属酸化物複合材料および該材料を用いる電気化学的キャパシタ
Document Type and Number:
Japanese Patent JP2004503456
Kind Code:
A
Abstract:
The present invention is related to carbon materials having 2-20 nm of mesopore and high porosity, carbon/metal oxide composites which are prepared with said material and wherein metal oxides are deposited in the pores, electrical double-layer capacitors prepared with said carbon material, and electrochemical capacitors prepared with said carbon/metal oxide composite. When the mesoporous carbon is used as an electrode material of electrical double-layer capacitors, in spite of low capacitance value per weight for low surface area, said electrical double-layer capacitor has higher charge storage volume than the previous ones due to low equivalent series resistance. Furthermore, when said carbon/metal oxide composite is used as an electrode material of electrical double-layer capacitor, the capacitor has high capacitance value per unit weight, i.e., 254 F/g, by combining the electrical double-layer capacitor with the pseudo capacitor from the metal oxide.
