Title:
電極材乾燥方法および電極材乾燥装置
Document Type and Number:
Japanese Patent JP5272564
Kind Code:
B2
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.
