1. An electrochemical cell, comprising:
an anode disposed on an anode current collector;
a cathode disposed on a cathode current collector;
a first separator and a second separator disposed between the anode and the cathode, the first separator having a first length, and the second separator having a second length longer than the first length; and
an interlayer including a conductive material disposed on the second separator, such that a portion of the interlayer is not coupled to the first separator.
