The dissolution of LiNO3 in carbonate electrolytes is achieved by introducing pyridine as a new carrier solvent owing to its higher Gutmann donor number than NO3-. The Li metal anode in LiNO3-containing carbonate electrolyte demonstrates a much enhanced reversibility due to the preferential reduction of LiNO3 and the formation of an inorganic-rich SEI.
