Abstract: To improve the performance of certain multivalent metal electrodes, the electrodes can be treated prior to use in an electrochemical cell by applying a solution comprising an acid to a surface of a multivalent metal electrode, then removing excess solution comprising the acid and drying the surface of the multivalent metal electrode. The resulting electrode has an outer interphase layer comprised of a hydrated hydroxychloride comprising the multivalent metal, where the interphase layer has a thickness of less than 5 μm.
