METHOD FOR MANUFACTURING BATTERY AND BATTERY

A method for manufacturing a battery includes: a step of obtaining a resin current collector by applying a first slurry containing a first resin and a second resin to one or both surfaces of a substrate and solidifying the first slurry to form a resin layer; and a step of obtaining an electrode by applying a second slurry containing an electrode active material and a solvent to the resin layer of the resin current collector and solidifying the second slurry to form an electrode active material layer. The first resin is a resin that is not soluble in the solvent of the second slurry. The second resin is a resin that is soluble in the solvent of the second slurry.
