The disclosure concerns an electrochemical cell including a cathode, an electrolyte, and an anode including an elemental metal or metal alloy. The electrolyte includes an electrolyte salt, an ionic liquid, and an optional first polymer binder. The electrolyte and/or the anode further includes a protective metal salt in an amount sufficient to (i) reduce or eliminate hydrogen evolution or open circuit side reactions in the electrochemical cell, or (ii) plate out onto or alloy with the anode metal or conductive additives in the anode. The electrochemical cell may further include a first current collector in contact with the cathode, and a second current collector in contact with the anode. The second current collector may include a metal or metal alloy. In such cells, the second current collector may further include the protective metal salt, and the protective metal salt may plate out onto or alloy with the metal or metal alloy of the second current collector.
