It is an object of the present invention to provide a nonaqueous electrolyte secondary battery, a method for producing the same, and the like, which can dramatically improve the dispersibility of a carbon conductive agent and form a good conductive network. . After mixing a polyvinylpyrrolidone polymer and a polyglycerol condensed ricinoleic acid ester as N-methyl-2-pyrrolidone as a dispersion medium as a dispersing agent, acetylene black is added to this, and a carbon slurry is further prepared, The positive electrode active material and the binder are mixed with this carbon slurry to produce a positive electrode active material slurry, and after producing the positive electrode 11 using the positive electrode active material slurry, the nonaqueous electrolyte secondary battery is produced using the positive electrode 11. do. |
