ABSTRACT:
A current collector device for an 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 resistance. A coating of material which includes an etching agent and a primer are both applied to the surface of the aluminum current collector in a single mixture so that actual etching and bonding of the primer to the surface can be accomplished by a single step. It is also contemplated that the primer material act as an electrode material which enables electrochemical activity with the particular ions in an electrolyte within the electrolytic cell.
