Patent ID: 8067058

Claim:
A method for producing a battery electrode, comprising the steps of: rotating a gravure roll with a plurality of depressions formed on an outer surface, and supplying a paint for forming a porous heat-resistant layer to the outer surface of the gravure roll so that the paint is carried on the outer surface of the gravure roll; removing an excess amount of the paint carried on the outer surface of the gravure roll with a resin blade that is disposed so that one end thereof contacts the outer surface of the gravure roll; causing blade holding means to change the position at which the resin blade contacts the outer surface of the gravure roll and the part of the resin blade in contact with the outer surface of the gravure roll to control the amount of the paint carried on the outer surface of the gravure roll, the blade holding means including a blade holding part for holding the resin blade, a pivot for supporting the blade holding part rotatably, and pivot moving means for moving the pivot upward and downward in the vertical direction; transporting an electrode in the direction opposite to the rotation direction of the gravure roll; and bringing a surface of the electrode into contact with the outer surface of the gravure roll to transfer the paint carried on the outer surface of the gravure roll to the surface of the electrode.
