ABSTRACT:
A nonaqueous secondary battery comprises an anode active material comprising a carbonaceous material, an electrolyte and a cathode active material comprising a lithium-containing transition metal chalcogenide. The carbonaceous material is obtained by burning a polyacrylonitrile fiber and has length of a crystallite in the c-axis direction of 75 to 250 .ANG. and an interval of 002 faces of 3.41 to 3.44 .ANG., the length and the interval being determined from an X-ray diffraction spectrum thereof using a Cu-K.alpha. ray.
