1. A rechargeable electrochemical cell, comprising:
a first electrode;
a second electrode;
a separator; and
an electrolyte, wherein the electrolyte comprises a salt with a concentration of greater than or equal to 0.01 M, the electrolyte having a portion of a precursor to form the separator, wherein the precursor for the separator is present in the electrolyte at a concentration of greater than or equal to 1 nM and less than or equal to 1 mM; and
wherein the precursor reacts to repair one or more defects in the separator when the first and the second electrodes reach a specific voltage between 0 V and 5 V.
