COMPOSITE CURRENT COLLECTORS INCLUDING A FIBROUS MEMBRANE AND A CONDUCTIVE MATERIAL AND/OR A METAL COATING

A battery cell includes A anode electrodes each including an anode active material layer arranged on an anode current collector, C cathode electrodes each including a cathode active material layer arranged on a cathode current collector, and S separators, where A, C, and S are integers greater than one. At least one of the anode current collector and the cathode current collector includes a composite current collector including a fibrous membrane coated with a conductive material.
