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.

Abstract The ability to rapidly charge batteries is crucial for widespread electrification across a number of key sectors, including transportation, grid storage, and portable electronics. Nevertheless, conventional Li‐ion with organic liquid electrolytes face significant technical challenges in achieving rapid charging rates without sacrificing electrochemical efficiency safety. Solid‐state (SSBs) offer intrinsic stability safety over their counterparts, which can potentially bring exciting opportunities fast applications. Yet realizing fast‐charging SSBs remains challenging due several fundamental obstacles, slow Li + transport within solid electrolytes, sluggish kinetics the electrodes, poor electrode/electrolyte interfacial contact, as well growth dendrites. This article examines SSB through comprehensive review materials strategies (ceramics, polymers, composites), composites. In particular, methods enhance ion crystal structure engineering, compositional control, microstructure optimization are analyzed. also addresses interface/interphase chemistry mechanisms, providing insights guide material design interface next‐generation SSBs.
