PROBLEM TO BE SOLVED: To provide a positive electrode for lithium ion secondary battery exhibiting excellent durability by producing an appropriate amount of lithium carbonate on the surface of a positive electrode active material thereby preventing deterioration thereof.SOLUTION: The manufacturing method of an electrode for a secondary battery includes a step S10 for preparing a pasty composition by dispersing a positive electrode active material, a conductive material and a binder into an organic solvent in an atmosphere where the dew-point temperature is -10°C or higher and 7°C or lower, the dry-bulb temperature is 20°C or higher and 30°C or lower, and the relative humidity is 5% or more and 45% or less, and a step S20 for forming a positive electrode mixture layer by coating the surface of a positive electrode collector with the composition. |
