    摘要： An electrode has a current collector having a plurality of through holes, and active material layers provided on both sides of the current collector, the current collector has projections extending on the top side or on the back side of the current collector from respective edges of the through holes, and an angle between each of the projections and a surface direction of the current collector is in the range of 30 to 80°. Because of the configuration wherein the projections are surrounded by the active material layers, a physical anchor effect is achieved so as to provide high adhesion. Since the projections are inclined relative to the surface direction of the current collector, the distance becomes shorter between the current collector including the projections and an active material, which was located apart from the projections in the case where the projections extended perpendicularly to the surface direction of the current collector. Therefore, electrically conducting paths become shorter and impedance is reduced.

    摘要： An electrode manufacturing method which can form a flat short-circuit prevention coating film (solid polyelectrolyte layer) having a uniform thickness and prevent short circuits from occurring in an electrochemical device is provided. The electrode manufacturing method comprises a first step of applying an active material layer coating material containing an active material particle, an active material layer binder, and a first solvent to a current collector so as to form a coating film made of the active material layer coating material; a second step of applying a second solvent to the coating film; and a third step of applying a solid polyelectrolyte layer coating material containing a solid polyelectrolyte, a solid polyelectrolyte layer binder, and a third solvent to the coating film coated with the second solvent. The first solvent is a good solvent for the active material layer binder, the second solvent is a poor solvent for the solid polyelectrolyte layer binder, and the third solvent is a good solvent for the solid polyelectrolyte layer binder.
