Concentrated dual-salt electrolytes for improving the cycling stability of lithium metal anodes

Lithium(Li) metal is an ideal anode material for rechargeable Li batteries, due to its high theoretical specific capacity(3860 mAh/g), low density(0.534 g/cm~3), and low negative electrochemical potential(-3.040 V vs. standard hydrogen electrode). In this work, the concentrated electrolytes with dual salts, composed of Li[N(SO_2F)_2](Li FSI) and Li[N(SO_2CF_3)_2](Li TFSI) were studied. In this dual-salt system, the capacity retention can even be maintained at 95.7%after 100 cycles in Li|Li FePO_4 cells. A Li|Li cell can be cycled at 0.5 mA/cm~2 for more than 600 h, and a Li|Cu cell can be cycled at 0.5 m A/cm~2 for more than 200 cycles with a high average Coulombi efficiency of 99%. These results show that the concentrated dual-salt electrolytes exhibit superior electrochemical performance and would be a promising candidate for application in rechargeable Li batteries.
