Abstract
A method of making metal hydroxide plate blanks for use in an electrochemical cell which includes compressing a porous metal web in at least one compression zone to a substantially non-porous state, attaching at least one a non-porous strip of the same metal to the porous metal web in the area of the compression zone, impregnating the porous metal web with a coating of electrochemically active material to form an impregnated web, removing excess coating from the impregnated web, drying the impregnated web, and dividing the dried web into plate blanks in the area of the metal strip. The metal is selected from the group consisting of nickel, silver and copper, with the preferred metal being nickel. An apparatus for practicing the invention is also disclosed which includes a device for compressing a porous metal web in a compression zone, a device for attaching at least one non-porous strip of the same metal to the porous metal web in the area of the compression zone, a coating device for impregnating the porous metal web with a coating of electrochemically active material, a device for removing excess coating from the impregnated web, a device for drying the impregnated web, and a de…
