摘要：

A combination of lithium bis(fluorosulfonyl)imide (LiFSI) and LiNO3 is designed to improve the oxidation resistance of cyclic ether (tetrahydrofuran) electrolyte at conventional concentration (1M LiFSI). The addition of NO3- results in the formation of a uniform N- and F-rich cathode electrolyte interphase, which enables 90% capacity retention of Li parallel to LiNi0.80Co0.10Mn0.10O2 batteries over 80 cycles coupled with a thin lithium metal anode (50 mu m) and a high-capacity cathode (similar to 3 mA h cm(-2)).
