    • 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 core 12 and the current collector allows for passage therethrough 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.
    • 提供了用于电化学电池的集电器。 该集电器包括:包含聚合物并具有连续孔隙率的网状芯; 第一网状表面; 与所述第一网状表面相对的第二网状表面; 以及设置在所述第一和第二网状表面中的至少一个上的金属薄膜,其中所述集流体具有连续的孔隙率。 对于集电器在生产或使用期间可能暴露于高温的网状芯来说,优选耐高温聚合物。 根据包括集流体的电化学装置的操作所需,网状芯12和集流体的连续孔隙率允许电解质和离子通过其中。 还提供了用于制造集电器的各种方法,包括其中提供包含聚合物的网状芯并且将薄金属膜沉积在网状芯的第一或第二网状表面中的至少一个上以形成 集电器。 还提供了包括集电器的电极组件以及包括至少一个集电器的电化学电池。
