摘要	In this study, self-synthesized lithium trifluoro(perfluoro-tert-butyloxyl)borate (LiTFPFB) is combined with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) to formulate a novel 1 m dual-salt electrolyte, which contains lithium difluorophosphate (LiPO2F2) additive and dominant carbonate solvents with low melting point and high boiling point. The addition of LiPO2F2 into this novel dual-salt electrolyte dramatically improves cycleability and rate capability of a LiNi0.5Mn0.3Co0.2O2/Li (NMC/Li) battery, ranging from -40 to 90 degrees C. The NMC/Li batteries adopt a Li-metal anode with low thickness of 100 mu m (even 50 mu m) and a moderately high cathode mass loading level of 10 mg cm(-2). For the first time, this paper provides valuable perspectives for developing practical lithium-metal batteries over a wide temperature range.
