A zinc electrode used in an electrochemical cell that can be used for charging with improved cycle life is provided. The solid active material of the electrode comprises a source of electrochemically active zinc and at least one fatty acid, or a salt, ester, or derivative thereof, or an alkylsulfonic acid, or a salt, ester, or derivative thereof. Including. This zinc electrode has a lower shape change compared to known zinc electrodes, reduced dendrite formation, and results in an electrochemical cell with improved capacity retention over many charge / discharge cycles.
