Abstract Composite solid electrolytes (CSEs) are promising for solid-state Li metal batteries but suffer from inferior room-temperature ionic conductivity due to sluggish ion transport and high cost expensive active ceramic fillers. Here, a host–guest inversion engineering strategy is proposed develop superionic CSEs using cost-effective SiO 2 nanoparticles as passive hosts poly(vinylidene fluoride-hexafluoropropylene) (PVH) microspheres polymer guests, forming an unprecedented “polymer guest-in-ceramic host” (i.e., PVH-in-SiO ) architecture differing the traditional “ceramic guest-in-polymer host”. The exhibits excellent Li-salt dissociation, achieving high-concentration free + . Owing low diffusion energy barriers coefficient, thermodynamically kinetically favorable migrate at /PVH interfaces. Consequently, delivers exceptional of 1.32 × 10 −3 S cm −1 25 °C (vs typically −5 –10 −4 high-cost ceramics), achieved under ultralow residual solvent content 2.9 wt% 8–15 in other CSEs). Additionally, electrochemically stable with anode various cathodes. Therefore, demonstrates high-rate cyclability LiFePO 4 |Li full cells (92.9% capacity-retention 3C after 300 cycles °C) outstanding stability high-mass-loading (9.2 mg high-voltage NCM622 (147.1 mAh g ).

Indium-MOF as Multifunctional Promoter to Remove Ionic Conductivity and Electrochemical Stability Constraints on Fluoropolymer Electrolytes for All-Solid-State Lithium Metal Battery

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 Suppressing the interface deterioration and sodium dendrites growth is crucial for achieving long‐life polyethylene oxide (PEO)‐based all‐solid‐state metal batteries. Herein, we systematically screen Sb 2 S 3 use as a PEO‐based solid‐state electrolyte (PSE) additive through theoretical calculations, in situ construct highly stable solid interphase (SEI) enriched with Na Sb. This SEI, characterized by its low reduction reaction activity, high ionic conductivity, strong affinity, significantly inhibits interfacial side reactions, accelerates ion transport, facilitates smooth + deposition. Moreover, incorporation of effectively enhances mechanical robustness, transference number, conductivity composite film (Sb @PSE), thereby mitigating formation. Consequently, remarkable electrochemical performances @PSE symmetric battery (achieving 5200 h at 0.1 mA cm −2 , 520 times longer than that pristine PSE), V (PO 4 ) |Sb @PSE|Na full high‐capacity retention 91% after 1000 cycles, are demonstrated. work, which emphasizes construction provides significant guidance to suppress degradation
