Original Abstract Submitted
An electrode for a non-aqueous electrolyte rechargeable battery and includes a current collector, an electrode mixture layer, and a base layer between the current collector and the electrode mixture layer. The base layer includes a styrene-acrylic acid ester-based copolymer, a carbon material, and/or a poly(meth)acrylic acid, and a content of the styrene-acrylic acid ester-based copolymer in the base layer may be greater than or equal to about 70 mass % and less than or equal to about 90 mass %. The poly(meth)acrylic acid has carboxyl groups that may not be neutralized, or a proportion of the carboxyl groups may be neutralized by alkali metal ions to be at most 25%. A weight per unit area of the electrode mixture layer per one surface of the current collector may be between about 10 mg/cmand about 35 mg/cm.
