Abstract
A method for manufacturing a spiral-wound battery is provided. The method includes the following steps: performing surface plasma treatment on a current collector; coating electrode slurry on a surface of the current collector, to form an electrode foil; performing surface plasma treatment on an isolating film, to improve hydrophilia of the isolating film; arranging and electrically connecting a plurality of metal conductive handles to the electrode foil, where the electrode foil is divided into a plurality of sections, and each section of the electrode foil corresponds to a jelly roll; and sequentially winding the isolating film and the electrode foil to form the spiral-wound battery. According to the method for manufacturing a spiral-wound battery provided in the present disclosure, internal impedance of a jelly roll is effectively reduced, and advantages of a high yield and low costs of a manufacturing process of the spiral-wound battery are maintained.
