1. A method of operating an electrochemical cell, the electrochemical cell including a first electrode disposed on a first current collector, a second electrode disposed on a second current collector, a first separator, a second separator, and an interlayer disposed between the first separator and the second separator, the method comprising:
measuring a voltage between the first electrode and the interlayer, the interlayer including a conductive material disposed on at least one of the first separator or the second separator; and
transferring electrical energy from at least one of the first electrode or the second electrode to the interlayer, such that the voltage is maintained above a threshold voltage.
