PURPOSE:To form a lengthy positive electrode plate having excellent characteristic without damaging a positive electrode active material by using a solvent mainly consisting of petroleum saturated hydrocarbon as a wetting agent at the time of mixing and kneading of a positive electrode mixture. CONSTITUTION:A negative electrode 4 having a chargeable and dischargeable light metal or its ion body as an active material, a nonaqueous electrolyte, and a positive electrode 5 consisting of at least one active material of the general formulae LixCoO2 (0<x<=1) and Li1+yMn2-zAzO4 (0<=y<=1, 0<z<=0.5, A is at least one element selected from the group consisting of Ti, V, Cr, Mo, Ni and Fe) are provided. The positive electrode 5 is formed by kneading and charging LixCoO2 or Li1+yMn2-zAzO4, the conductive agent, and a resin mainly containing ethylene polytetrafluoride resin by use of a solvent mainly consisting of petroleum saturated hydrocarbon. |
