Abstract:
1. A method for manufacturing a positive electrode for a nonaqueous electrolyte secondary battery, the method comprising: forming a positive electrode active material layer on a surface of a positive electrode collector; and coating an inorganic particle slurry containing inorganic particles, carboxymethyl cellulose, and a binder on a surface of the positive electrode active material layer and thereafter drying the slurry to form a porous inorganic particle layer, the inorganic particle slurry containing carboxymethyl cellulose having an etherification degree of 0.8 or more and a viscosity of 800 mPa·s or more in a 1% aqueous solution at a ratio of 0.2% by mass or more and 1.0% by mass or less with respect to the inorganic particles.
