Scientists have developed a method for the electrochemical synthesis of ammonia from nitrogen (N2), where the improved diffusion of lithium ions (Li-ion) increases the current efficiency to 100 mA cm−2. The study achieved a significantly improved conversion efficiency of N2 to NH3 at this high current density. The process uses lithium-mediated reduction of nitrogen in an organic electrolyte under atmospheric pressure. The main finding is that optimized Li-ion diffusion minimizes side reactions and increases ammonia selectivity. Experiments have shown stable production of NH3 with high efficiency during a long-term run. The results were published in the journal Science (Vol. 391, No. 6786, pp. 724-729, February 2026). This technology promises more efficient production of ammonia at higher currents compared to previous methods.
