Activation of trace LiNO3 additives by BF3 in high-concentration electrolytes towards stable lithium metal batteries

Abstract

The activation of trace LiNO₃ additives in high-concentration electrolytes is achieved by BF₃ due to its Lewis acidity. This advanced electrolyte can promote the decomposition of LiNO₃ into Li₃N, attaining enhanced cycle reversibility of lithium anodes, which broadens the application of LiNO₃ additives.
