An inorganic-rich SEI induced by LiNO3 additive for a stable lithium metal anode in carbonate electrolyte

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 reductio...

Summary: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.
