In article number 2001989, Xianhong Rui, Yan Yu, and co‐workers develop a Li salt, lithium bisoxalatodifluorophosphate (LiDFBOP), to modify the solid‐electrolyte interphase (SEI) in fluoroethylene carbonate (FEC)–based electrolyte for lithium metal batteries. Benefiting from the synergetic effect of the LiDFBOP and FEC, a fluorinated SEI rich in LiF and Li x PO y F z species is achieved, demonstrating the improved stability and ionic conductivity for fast Li + transportation.
