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.

Lithium metal batteries have gained significant attention due to their high energy density, making them a promising candidate for various applications, including electric vehicles and grid-scale storage. Nevertheless, the practical development of lithium faces challenges related dendrite formation, low cycling efficiency, poor safety use liquid electrolytes. Solid-state electrolytes (SSEs) are most attractive alternatives next-generation safe high-energy density storage systems. However, conventional SSEs fail meet simultaneous demands ionic conductivity mechanical properties, intrinsic solid-state chemical properties. Among numerous modifying strategies SSE chemistry, composite polymer (CPEs) with advanced nanocomposite design display suitable processability, wettability, flexibility, cost production. This review comprehensively outlines merits functions designs in CPEs. provides valuable insights into recent progress electrolytes, offering guidance future research efforts this field.

The development and application of polyethylene oxide (PEO) based solid polymer electrolyte (SPE) is severely constrained by its low ionic conductivity poor tensile resistance. To improve the electrochemical performance SPE without losing mechanical properties, a benzene sulfonate-based additive adopted into crosslinking system composed -CH 2 -O- segments to obtain membrane with high 1.47 × 10 −4 S cm −1 an transference number 0.70 at room temperature. activation energy value 0.128 eV gives evidence for favorable migration mechanism PTH-SPE. Anti-dendrite growth contact optimization can be realized molecular structure design elongation 490%. reversible overpotential Li||Li symmetric cell within 1000 h demonstrates that compact PTH-SPE inhibit lithium dendrite. This work provides new strategy designing high-performance electrolytes temperature via green solvent-free method.
