Abstract
A battery cell includes C cathode electrodes each including a cathode active material layer and a cathode current collector, A anode electrodes each including an anode active material layer and an anode current collector, and S separators, where C, A, and S are integers greater than one. An interlayer is arranged between each of the S separators and the cathode active material layer of each of the C cathode electrodes. The interlayer includes a porous conductive network including one of a wire mesh layer and a perforated metal layer.
