PROBLEM TO BE SOLVED: To provide a non-aqueous secondary battery with its superior discharge capacity by burning a thermosetting resin and providing a glass-shaped carbon material with a specified atom number ratio and specific surface area of hydrogen and carbon as a negative electrode material of a non-aqueous battery. SOLUTION: A glass-shaped carbon material in which thermosetting resin is burned is used for a negative electrode material for non-aqueous battery. In this carbon material, the atom number ratio between hydrogen and carbon (H/C) is 0.15 to 0.5, and the specific surface with the BET method is 100 to 500m<2> /g. Furthermore, in the case of the glass-shaped carbon material it is preferable that the intra-planar interval doo2 is 3.37Å or more and the crystal size Lc is 50Å or less. In addition, it is preferable that the glass-shaped carbon material is 2.0g/cm<3> in the degree of vacuum and 0.1 to 50μm in particle size. The thermosetting resin preferably uses a copolycondensation body of phenol, furfurly alcohol, and formaldehyde. |
