Abstract Composite solid‐state electrolytes (CSSEs) that combine the benefits of inorganic and polymer hold great potential for lithium metal batteries (SSLMBs) due to their high ionic conductivity superior mechanical properties. However, overall performance is severely hindered by several practical challenges, including component aggregation, poor interface behavior, limited Li + transport. Here, a unique ultrathin coating triaminopropyl triethoxysilane with bifunctional structure introduced effectively bridges fillers (Li 1+x Al x Ti 2‐x (PO 4 ) 3 , LATP) polyvinylidene fluoride hexafluoropropylene /polyethylene oxide matrix, thereby enabling high‐performance CSSEs (referred as SLPH). This design prevents LATP particle agglomeration, improves interfacial compatibility, ensures enrichment fast transport within SLPH. Consequently, SLPH exhibits low conduction energy barrier ( E = 0.462 eV), desirable (4.19 × 10 −4 S cm −1 at 60 °C), transference number 0.694). As result, SSLMBs SLPH, Li| |Li symmetric cells, LiFePO | coin‐type, pouch demonstrate rate capability long‐time cycling stability. work underscores significance surface functionalization create stable solid‐solid enhance conduction, paving way in SSLMBs.

Abstract Solid polymer electrolytes are emerging as a key component for solid‐state lithium metal batteries, offering promising combination of large‐scale processability and high safety. However, challenges remain, including limited ion transport the unstable solid electrolyte interphase, which result in unsatisfactory ionic conductivity uncontrollable dendrite growth. To address these issues, high‐throughput Li‐ion pathway is developed by incorporating tungsten sulfide enriched with sulfur vacancies (SVs) into poly(vinylidene fluoride‐co‐hexafluoropropylene)‐based composite (CPEs). The SVs strong interaction CPEs facilitates homogeneous 1.9 × 10 −3 S cm −1 at 25 °C) enhancing dissociation salts effectively creates ample interfaces chains to reduce formation inner vacuities. Moreover, confine FSI − anions, while electron‐rich environment induced atoms promotes preferential degradation bis(trifluoromethanesulfonyl)imide ensuring uniform deposition. This fosters inorganic nanocrystals on anode suppresses growth, enabling an ultra‐long lifetime over 5500 h Li||Li symmetric cells. When paired sulfurized polyacrylonitrile cathode, pouch cell capacity 0.524 Ah achieved, demonstrating effectiveness homogeneous, Li‐ions mechanism.

Abstract Polyacrylonitrile (PAN) is a promising polymer for solid‐state lithium (Li) metal batteries (SSLMBs). However, the low ionic conductivity of PAN‐based solid electrolytes (SPEs) and unstable Li/PAN interface hinder applications PAN in SSLMBs.

Hard carbon is a promising candidate for potassium ion batteries due to its large interlayer spacing and abundant closed pores. However, the slow migration sluggish diffusion kinetics of ions lead inferior insertion pore-filling processes, causing severe channel blocking, continuous byproduct generation, poor cycling stability. In this study, we coated hard on top tetragonal barium titanate particles forming ferroelectricity-aided anode (t-BTO@C). The t-BTO@C exhibits higher interfacial charge density, enhanced insertion-pore filling capacity, formation fewer byproducts. effective interaction between spontaneous polarization electric field t-BTO accelerates ensures homogeneous ions, as well improvement storage. After 100 cycles at 0.05 A g-1, shows specific capacity 374.9 mA h than those SiO2@Carbon (97.2 g-1) Pure Carbon (240.1 g-1). Paired with Prussian white cathode, full cell 313.0 g-1 0.1 88.9% retention after 40 cycles, much in recent reports. Our strategy provides new path improve performance batteries.
