<P>PROBLEM TO BE SOLVED: To provide a lithium secondary cell having enough active material intensity and adhesiveness in an anode by making exist a spherical substance in an anode active material layer with the use of a scale-like carbon substance, even if housed in a case having shape changeability. <P>SOLUTION: In the lithium secondary cell made by housing lithium secondary cell elements consisting of a cathode, an anode and electrolyte in a case having shape changeability, the anode contains a scale-like carbon substance with an aspect ratio of 1.1 to 2.9, and a spherical substance with an aspect ratio of 1.0 to 1.5, and the scale-like carbon substance is a graphite carbonaceous object at least with a part of the surface coated with amorphous coke, with the spherical graphite of meso-carbon micro beads. <P>COPYRIGHT: (C)2008,JPO&INPIT |
