Abstract: The invention relates to an electrode suitable for a chargeable/dischargeable secondary battery in which a carbonaceous material capable of doping and dedoping of lithium ions is used as a negative electrode active material wherein carbon fibers are used as the carbonaceous material in a form of an uni-directionally arranged body or in combination of electrically conductive foil or fibers, and further relates to a secondary battery using the electrode. The invention enables to provide a secondary battery having high capacitance and high outputtng property.

Abstract: An electrode using carbon fibers as the carbon material, and a chargeable/dischargeable secondary cell comprising the electrode and a cathode active material of carbon material which can be doped with lithium ions and from which the ions can be removed. The carbon fibers are oriented in one direction or the fibers are mixed with electrically conductive foils or fibers. Thus a large-capacity high-output secondary cell is provided.
