This work presents a facile synthesis approach for core–shell structured Li2S nanoparticles with Li2S as the core and Li3PS4 as the shell. This material functions as lithium superionic sulfide (LSS) cathode for long-lasting, energy-efficient lithium–sulfur (Li–S) batteries. The LSS has an ionic conductivity of 10–7 S cm–1 at 25 °C, which is 6 orders of magnitude higher than that of bulk Li2S (∼10–13 S cm–1). The high lithium-ion conductivity of LSS imparts an excellent cycling performance to all-solid Li–S batteries, which also promises safe cycling of high-energy batteries with metallic lithium anodes.read more

TL;DR: In this paper, the authors reviewed the challenges for further development of Li rechargeable batteries for electric vehicles and proposed a nonflammable electrolyte with either a larger window between its lowest unoccupied molecular orbital and highest occupied molecular orbital (HOMO) or a constituent that can develop rapidly a solid/ electrolyte-interface (SEI) layer to prevent plating of Li on a carbon anode during a fast charge of the battery.
