Abstract

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.
