Lithium Metal Batteries: The Synergetic Effect of Lithium Bisoxalatodifluorophosphate and Fluoroethylene Carbonate on Dendrite Suppression for Fast Charging Lithium Metal Batteries (Small 30/2020)

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 LixPOyFz species is achieved, demonstrating the improved stability and ionic conductivity for fast Li+ transportation.
