PROBLEM TO BE SOLVED: To restrain the destruction of an electrode following a charging/ discharging cycle, to improve high capacity, long time reliability, and battery capacity, by constituting a battery of a positive electrode composed of a metallic oxide containing Li and Ni, a negative electrode composed of iron oxide doping/ dedoping the Li and a nonaqueous electrolyte. SOLUTION: Slurry; wherein a positive electrode mixture, obtained by mixing (a metallic oxide containing the Li and Ni in a formula LiNix M(1-x) O2 (0.5<=x<=0.95, M: transition metals and/or Al), a conductive agent, and a binding agent), is dispersed in a solvent; is dried and powdered, and then compressedly formed together with a carrier to obtain a positive electrode 1. The positive electrode 1 is put into an aluminum clad can 3, and thereon a separator 4 is placed to inject a nonaqueous electrolyte. Then, a negative electrode 2; composed of iron oxide for doping/dedoping the Li, the conductive agent, and the binding agent; is placed onto the separator 4 to be sealed by an insulating gasket 5 and an anode cup 6. |
