Abstract
A method of producing an anode unit, whose active material consists of an alloy of an alkaline metal and a host metal therefore. An elongated element of the host metal is enclosed in a separator in form of a hollow fiber and is put in electrochemical contact with an organic solution of the alkaline metal, which migrates through the hollow fibre wall for alloying the host metal element. In a preferred embodiment strips are punched out at distances from each other in a sheet of the host metal and films of hollow fiber materials, laid on the two surfaces of the sheet, are welded together in the openings left after the punching for forming hollow fibers.
