  • Method and apparatus for drying electrode material
    Patent number: 9310130
    Abstract: An electrode material drying method and apparatus for drying electrode material are provided for achieving quality improvement of batteries. Electrode material portions containing a solvent are spaced apart from each other on the metal foil. An inductive coil that inductively heats the metal foil faces the metal foil. An amount of heat applied to an uncoated portion of the metal foil between the electrode material portions is reduced below that of a coated portion of the metal foil on which the electrode material portions are arranged. The heat evaporates the solvent in the electrode material portions by causing the metal foil to generate heat with inductive heating while moving the metal foil and the inductive coil relative to each other in an arrangement direction, that is, a direction in which the electrode material portions are arranged.
