Abstract
A cathode has a hollow body with opposed, spaced sheet-like parallel walls with outer faces on which metal is deposited during use of the cathode. The body has outer surfaces between the outer faces of the walls upon which substantially no metal is deposited during use of the cathode, so that metal is deposited as two separate sheets, one sheet on each wall. The hollow body is connectable to a source of reduced air pressure and the sheet-like walls are resiliently deformable to enable the walls to be inwardly bowed towards one another by reduced air pressure, after metal has been deposited on the walls, so as to effect separation of the deposited metal sheets from the walls.
