Abstract
A current collector for use in an electrochemical cell is provided. The current collector comprises: a reticulated core comprising a polymer and having continuous porosity; a first reticulated surface; a second reticulated surface opposite said first reticulated surface; and a thin metal film disposed on at least one of said first and second reticulated surfaces, wherein said current collector has continuous porosity. A high temperature resistant polymer is preferred for the reticulated core where the current collector may be exposed to high temperatures during production or use. The continuous porosity of the reticulated coreand the current collector allows for passage of electrolyte and ions, as necessary for operation of an electrochemical device that includes the current collector. Various methods for making the current collector are also provided, including an exemplary embodiment in which a reticulated core comprising a polymer is provided and a thin metal film is deposited on at least one of the first or second reticulated surface of the reticulated core to form the current collector. An electrode assembly which includes the current collector, as well as an electrochemical cell which includes at least one current collector, are also provided.
