LOW-CONCENTRATION ELECTROLYTE FOR SUPPRESSING DENDRITE GROWTH IN LITHIUM METAL

An electrolyte for a lithium battery containing a low concentration of gadolinium nitrate (Gd(NO)). In an electrolyte of 1 M lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), DME:DOL (1:1), and 1% LiNO, 1 mg/ml of Gd(NO)as additive will promote the plating/stripping of lithium metal with nodular morphology and support dendrite suppression so that less dead lithium is formed on Li anode surface.
