Li Metal Batteries: Lithium Difluorophosphate‐Based Dual‐Salt Low Concentration Electrolytes for Lithium Metal Batteries (Adv. Energy Mater. 30/2020)

In article number 2001440, Hongfa Xiang, Yan Yu and co-workers present dual-salt low concentration electrolytes for Li metal batteries to enable formation of a stable solid-electrolyte interphase (SEI). Li difluorophosphate and Li bis(oxalate)borate synergistically render a conductive and robust SEI layer, which allows uniform Li platting/stripping and stable cycling performance of Li||LiFePO4 cells.
