NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY BINDER COMPOSITION, ELECTRODE COMPOSITION, ELECTRODE SHEET, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, PRODUCTION METHOD FOR ELECTRODE SHEET, AND PRODUCTION METHOD FOR SECONDARY BATTERY

WIPO Patent Application WO/2021/210603

A1

A non-aqueous electrolyte secondary battery binder composition that contains a binder in an aqueous medium that includes water, the binder being formed from a polymer that has a structural component that is represented by formula (J-1), and the water content of the composition being at least 10 mass%. An electrode composition that includes the binder composition and an electrode active material. An electrode sheet that has a layer that is formed from the electrode composition and a production method for the electrode sheet. A non-aqueous electrolyte secondary battery that has, in order, a positive electrode active material layer, a separator, and a negative electrode active material layer, at least one of the active material layers being formed from the electrode composition and a production method for the non-aqueous electrolyte secondary battery.
