Abstract
The present invention is directed to a non-aqueous electrolyte battery comprising an anode, a cathode using a carbon material, and a non-aqueous electrolytic solution, wherein the carbon material obtained by coating a core composed of graphitized carbon in which spacing (d.sub.002) of lattice planes (002) is in the range of 3.35 to 3.39 .ANG. and the length (Lc) of a crystallite in the direction of the c axis is not less than 1000 .ANG. with coating graphitized carbon in which spacing (d.sub.002) of lattice planes (002) is more than that in the graphitizing carbon and is in the range of 3.36 to 3.48 .ANG., the carbon material obtained by coating a core composed of graphitized carbon in which spacing (d.sub.002) of lattice planes (002) is in the range of 3.35 to 3.39 .ANG. with a calcined product of an organic substance composed of carbon containing sulfur atoms, or the carbon material composed multi-phase graphitized carbon having two or more crystals respectively different crystallinities in one particle, the length (Lc) of a crystallite in the direction of the c axis in each of the crystals being not less than 10 .ANG., are used for the cathode.
