NOVELTY - A nonaqueous secondary battery (100), comprises an electrode group (110) including positive electrode (111) having positive electrode current collector and positive electrode mixture layer, negative electrode (116) having negative electrode current collector and negative electrode mixture layer, and a separator (115) disposed between the positive electrode and the negative electrode; a nonaqueous electrolyte; and a case (120) enclosing the electrode group and the nonaqueous electrolyte.    USE - As nonaqueous secondary battery (claimed) e.g. a lithium ion battery.    ADVANTAGE - The nonaqueous secondary battery has high capacity and less cycle degradation. The nonaqueous secondary battery has a high percentage of the positive electrode active material in the positive electrode mixture layer and thus has high capacity. In addition, in the battery, the particulate binders are adhered on the surface of the positive electrode active material, and the positive electrode active material is not covered with a binder as in a conventional nonaqueous secondary battery. For this reason, in the battery, only a little surface area of the positive electrode active material is covered with a binder. Accordingly, since the positive electrode active material can more efficiently absorb and release a lithium ion, the nonaqueous secondary battery has higher capacity.    DETAILED DESCRIPTION - A nonaqueous secondary battery (100), comprises an electrode group (110) including a positive electrode (111) having a positive electrode current collector and a positive electrode mixture layer disposed on the positive electrode current collector, a negative electrode (116) having a negative electrode current collector and a negative electrode mixture layer disposed on the negative electrode current collector, and a separator (115) disposed between the positive electrode and the negative electrode; a nonaqueous electrolyte; and a case (120) enclosing the electrode group and the nonaqueous electrolyte, the positive electrode mixture layer or the negative electrode mixture layer containing active material particles and particulate binders adhered to the surface of the active material particle. An INDEPENDENT CLAIM is included for producing a nonaqueous secondary battery involving providing active material particles and particulate binders, mixing the active material particles and the particulate binders to obtain a mixed powder, and fixing the mixed powder on the positive electrode current collector or the negative electrode current collector.
