1. An electrochemical cell comprising:
an anode including an anode reductant;
an electrolyte including a salt of the reductant; and
a cathode including:
a cathode oxidant;
cathode-electrolyte interphase (CEI) extending through the cathode oxidant;
a solid-electrolyte-interphase (SEI) layer between the cathode oxidant and the electrolyte; and
an anode-reductant layer between the cathode oxidant and the electrolyte.
