PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic battery that has a good preservation characteristic by inhibiting lithium in a carbon material used in the negative electrode from causing a self-discharge on reacting with a solvent or the like in a nonaqueous electrolyte during preservation. SOLUTION: In a nonaqueous electrolytic battery having a positive electrode, a negative electrode that uses a carbon material, and a nonaqueous electrolyte, the carbon material used in the negative material comprises graphitized carbons serving as nuclei, with a spacing d002 ranging from 3.35 to 3.39Å on the (002) plane of their lattice plane and with the size Lc of a crystallite in the direction of the (c)-axis being 1000Å or more, and covered with covering graphitized carbons in which a spacing d002 on the (002) plane of their lattice plane ranges between 3.36 and 3.48Å and is therefore not less than the spacing d002 in the above graphitized carbons serving as nuclei. |
