▎ 摘  要

NOVELTY - Electrode has current collector, and an active material layer positioned on the electrode current collector, where the active material layer formed by coating an electrode slurry prepared with an aqueous solution includes a negative electrode active material, a conductive material, a surfactant, and a binder on the electrode current collector, where binder comprises a water-soluble polymer. USE - Electrode for secondary battery. ADVANTAGE - The electode provides improved dispersibility, and the viscosity of the electrode slurry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for manufacturing of electrode for secondary battery, which involves preparing a first solution by mixing an anode active material and a conductive material in an aqueous surfactant solution, preparing an electrode slurry by mixing a binder with the first solution, and coating the electrode slurry on an electrode current collector, where the binder includes a water-soluble polymer.
