Abstract Fluoropolymers promise all-solid-state lithium metal batteries (ASLMBs) but suffer from two critical challenges. The first is the trade-off between ionic conductivity ( σ ) and anode reactions, closely related to high-content residual solvents. second, usually consciously overlooked, fluoropolymer’s inherent instability against alkaline anodes. Here, we propose indium-based metal–organic frameworks (In-MOFs) as a multifunctional promoter simultaneously address these challenges, using poly(vinylidene fluoride–hexafluoropropylene) (PVH) typical fluoropolymer. In-MOF plays trio: (1) adsorbing converting free solvents into bonded states prevent their side reactions with anodes while retaining advantages on Li + transport; (2) forming inorganic-rich solid electrolyte interphase layers PVH reacting promote uniform deposition without dendrite growth; (3) reducing crystallinity promoting Li-salt dissociation. Therefore, resulting PVH/In-MOF (PVH-IM) showcases excellent electrochemical stability anodes, delivering 5550 h cycling at 0.2 mA cm −2 remarkable cumulative capacity of 1110 mAh . It also exhibits an ultrahigh 1.23 × 10 −3 S −1 25 °C. Moreover, LiFePO 4 |PVH-IM|Li full cells show outstanding rate capability cyclability (80.0% retention after 280 cycles 0.5C), demonstrating high potential for practical ASLMBs.
