PROBLEM TO BE SOLVED: To provide an electrode mix for a nonaqueous battery positive electrode preventing the formation of gel and stable by adding an organic acid to a mix comprising an electrode active material, an auxiliary conductive material, a fluorovinylidene polymer, and an organic solvent. SOLUTION: 9 pts.wt. LiNi0.8 Co0.2 O2 serving as an active material, 0.7 pts.wt. conductive carbon black, 0.3 pts.wt. fluorovinylidine polymer, and 6 pts.wt. N-methyl-2-pyrrolidone to which 0.1wt.% maleic acid is added are mixed to prepare mix slurry for a positive electrode 1. The mix slurry is applied to the one side of a copper foil and dried to obtain an electrode structure having a smooth positive electrode layer. |
