Here, we show that protective Li<sub>3</sub>N coatings can be simply formed by the direct reaction of electrodeposited lithium electrodes with N<sub>2</sub> gas, whereas using battery-grade lithium foil is problematic due to the presence of a native passivation layer that hampers that reaction. The protective Li<sub>3</sub>N coating is effective at preventing lithium dendrite formation, as found from unidirectional plating and plating-stripping measurements in Li-Li cells. The Li<sub>3</sub>N coating also efficiently suppresses the parasitic reactions ofACS applied materials & interfacesCombined Electrochemical, XPS, and STXM Study of Lithium Nitride as a Protective Coating for Lithium Metal and Lithium-Sulfur Batteries.PMC10450643EP/N024303/1EP/S003053/1FIRG014Meddings NLee TLGarcia-Araez NFop SFitch SDSMoehl GESoule SKazemian MHector ALfalseCombined Electrochemical, XPS, and STXM Study of Lithium Nitride as a Protective Coating for Lithium Metal and Lithium-Sulfur Batteries.Li<sub>3</sub>N is an excellent protective coating material for lithium electrodes with very high lithium-ion conductivity and low electronic conductivity, but the formation of stable and homogeneous coatings is technically very difficult.
