Abstract
Corrosion of the current collectors in cells utilizing Vanadium Oxides and Chromates as cathode materials is prevented by the utilization of metals from Groups IVb, Vb and VIb of the Periodic Tables for fabricating the current collectors and leads in contact with the cathode materials. Ta, Ti, Mo and W, are preferred materials. Cells containing such structures are described as well as an intermediate protective structure.
Claims2
A cathode current collector assembly for use under corrosion-prone conditions which comprises a current collector body and a terminal tab welded thereto wherein only the immediate area where the tab is welded to said current collector is overlain, surrounded by and has heatsealed thereto foils consisting of polyolefin polymer.
