  • Publication number: 20250070129
    Abstract: An anode active material layer for a battery, wherein the anode active material layer includes a carbon-based anode active material and a binder coating the carbon-based anode active material, and the content of the binder is 4.0 to 9.0% by mass, and a coverage of the anode active material by the binder is 8.0 to 25%, an anode active material layer for a battery. A production method of an anode active material layer comprises: blending the carbon-based anode active material, and the 4.0% to 9.0% by mass of the binder with respect to the total amount of the anode active material layer, to prepare an anode composite material; and coating the anode composite material onto a substrate by a dry method to form the anode active material layer.

  • Publication number: 20250054938
    Abstract: A method of fabricating an electrode includes: fabricating a first electrode layer disposed on a current collector; and fabricating a second electrode layer disposed on the first electrode layer. The first electrode layer is formed by electrostatic deposition, wet deposition, or rolled film formation. The second electrode layer is formed by rolled film formation. When the first electrode layer is fabricated by rolled film formation, at least part of a surface of active material particles used in the rolled film formation is coated with a resin that is different from polytetrafluoroethylene.
