摘要： A liquid applicator comprises a guide roll for guiding a sheet, and a slit die, having a slit with an opening extending in an axial direction of the guide roll, for applying a liquid to a surface of the sheet guided by the guide roll. On the rear side of the opening in a rotating direction of the guide roll, the slit die further includes a front lip having a concave surface corresponding to the guide roll. The front lip opposes the guide roll by such a length FA in the rotating direction RD of the guide roll as to have a central angle θ of 0.95° to 3.0° about an axis O of the guide roll.

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.
