Abstract
A current collector device for a rechargeable electrolytic cell and method for manufacturing same. The device includes an aluminum current collector having a substantially reduced oxidation layer relative to its native oxide layer, to, in turn, exhibit a relatively low interfacial impedance. A layer of electrode material is applied and adhered to the surface of the aluminum current collector to enable electrochemical activity with the particular ions in an electrolyte within the electrolytic cell. A primer may be applied between the electrode material and the aluminum current collector, wherein the primer serves to substantially preclude re-growth of the oxide layer which would otherwise occur absent such a primer.
