摘要

PCT No. PCT/JP93/01880 Sec. 371 Date Nov. 21, 1994 Sec. 102(e) Date Nov. 21, 1994 PCT Filed Dec. 24, 1993 PCT Pub. No. WO94/15373 PCT Pub. Date Jul. 7, 1994The 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.
