1. A method of operating an electrochemical cell, the electrochemical cell including an anode disposed on an anode current collector, a cathode disposed on a cathode current collector, a first separator, a second separator, a third separator, a first interlayer disposed between the first separator and the second separator, and a second interlayer disposed between the second separator and the third separator, the method comprising:
measuring a first voltage between the anode and the interlayer, the interlayer including a carbonaceous material coated on at least one of the first separator or the second separator;
measuring a second voltage between the anode and the second interlayer; and
in response to the at least one of the first voltage or the second voltage being below a threshold voltage, closing a circuit between the anode and the cathode.
