PURPOSE: To provide a nonaqueous secondary battery with high capacity, long stability, and less charge/discharge capacity drop. CONSTITUTION: A nonaqueous secondary battery comprises a positive electrode, a negative electrode, and an electrolyte prepared by dissolving an electrolyte in a nonaqueous solvent. A porous mesocarbon microbead with a specific surface area of 10-700m<2> /g is used as a negative electrode material. |
