The invention regards a method for electrochemical ammonia synthesis, comprising the steps of: providing at least one electrolysis cell; contacting the cathode with a source of lithium cations, nitrogen, and protons; and subjecting the cathode to a continuous pulsed cathode potential, including a pulsed cathodic current load, wherein the cathode potential is pulsed between the lithium reduction potential and a less negative cathode potential, whereby ammonia is synthesized.
