Lithium metal batteries face critical challenges such as low ion transport efficiency under lean electrolyte conditions. Here, authors study a bifunctional ligand-bridged electrolyte containing ethyl difluoroacetate that can form interconnected ionic aggregates through hydrogen bonding and lithium-ion coordination interactions, suppressing parasitic reactions and enhancing interfacial charge transfer, enabling stable cycling of a 600 Wh kg-1 lithium metal 14 Ah pouch cell.
