| description | PROBLEM TO BE SOLVED: To improve a high rate characteristic and enhance a capacity and cycle life by providing positive and negative electrodes containing a material capable of storing and releasing lithium ion, and a nonaqueous electrolyte containing a lithium compound, and including a conductive agent consisting of a conductive material having a metal precipitated on the surface in at least one of the positive and negative electrodes. SOLUTION: At least one metal element ion selected from Au, Ag, Cu, Ni, Cr, and Zn is reduced on the surface of the conductive material of a nonaqueous secondary battery to precipitate the metal by electroless plating by oxidation- reduction reaction, and the precipitation quantity is set to 1 wt.% or more and 500 wt.% or less to a conductive agent. As the conductive material, at least one material selected from carbon materials, metal oxides and metals different from the metal to be precipitated is used. The negative electrode material comprises a composite oxide of Sn consisting of a material containing at least one of elements of Si, Ge, Fe, Ti, Nb, W and V. |
