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.

Abstract: A method for preparing an electrode is provided including generating aerosol droplets of a precursor capable of being converted into a component of an electrode in a carrier liquid; converting the droplets into precursor particles; converting the precursor particles into particles of the electrode component; and depositing the electrode component onto an electrically conductive substrate. The electrode is characterized by a highly porous structure having a surface area in the range of >4 m.sup.2 /g and a discharge density at least 1.5 times greater than comparable electrodes prepared by conventional methods.
