Solid-state batteries can ensure high energy density and safety in lithium metal batteries, while polymer electrolytes are plagued by slow ion kinetics low selective transport of Li+ . Metal-organic frameworks (MOFs) proposed as emerging fillers for solid-state poly(ethylene oxide)(PEO) electrolytes, however, developing functionalized MOFs understanding their roles on transfer has proven challenging. Herein, combining computational experimental results, the functional group regulation effectively change surficial charge distribution limit anion movement is revealed, providing a potential solution to these issues. Specifically, 2D MOF sheets designed through molecular engineering construct high-performance composite where electron-donating effect substituents 2D-MOFs limits ClO4- promotes mechanical properties migration numbers (0.36 up 0.64) PEO. As result, Li/Li cells with electrolyte exhibit superior cyclability 1000 h at current 0.2 mA cm-2 Meanwhile, solid LiFePO4 /Li battery delivers highly reversible capacities 148.8 mAh g-1 after 200 cycles. These findings highlight new approach confinement use electronic effects, leading enhanced ionic conductivity, feasible direction batteries.

Abstract Nanocomposite solid polymer electrolytes are considered as a promising strategy for solid‐state lithium metal batteries (SSLMBs). However, the randomly dispersed fillers in matrix with limited Li + transference number and insufficient ionic conductivity severely sacrifice ion transport capacity, thus restricting their practical application. To tackle these issues, magnetic field‐assisted alignment is proposed to disperse vertically aligned akaganéite nanotube an inorganic‐polymer nanocomposite electrolyte ultra‐stable SSLMBs. The cations Lewis acid sites can grab anions promote dissociation of salts while sufficient oxygen hydroxyl functional group offer abundant Li‐ion migration favored transportation. At same time, akaganéite/polymer interface combined above synergistic effects establish oriented channels inside electrolyte, which significantly elevates its conductivity. Specially, organic‐inorganic dual‐layer solid‐electrolyte formed uniform deposition suppress dendrite growth. beneficial effect network also demonstrated full cell pouch where remarkable 2000 cycles capacity decay 0.012% per cycle be achieved.

Abstract All‐solid‐state lithium metal batteries (ASSLMBs) hold great promise for the development of next‐generation high‐safety, high‐energy‐density batteries, but still face challenges dendrite growth and thickness. Herein, ultrathin PEO‐based composite solid polymer electrolyte (denoted as PAL) supported by a low‐density self‐supporting aramid nanofiber (ANF) aerogel framework is developed. The ANF obtained novel CO 2 ‐assisted induced self‐assembly method has well‐designed bilayer structure with double cross‐linking degree. Benefiting from intermolecular interaction between ANFs PEO, PAL achieves an thickness (20 µm) excellent thermal stability mechanical strength. Meanwhile, due to modulation ionic pathways functionalized ANF, uniform deposition without dendrites, resulting in stable long cycling (1400 h) symmetric cells. Consequently, Li|PAL|LiFePO 4 (LFP) cell long‐term (1 C, >700 cycles, Coulombic efficiency > 99.8%) fast charge/discharge performance (rate, 10 C). More practically, Li|PAL|LFP energy density 180 Wh kg −1 ability match high‐loading (8 mg cm −2 ) cathode. Furthermore, double‐layer pouch demonstrates flexibility safety abuse tests.

Abstract Poly(ethylene oxide) (PEO)‐based electrolytes are often used for Li + conduction as they can dissociate the salts efficiently. However, high entanglement of chains and lack pathways rapid ion diffusion limit their applications in advanced batteries. Recent developments ionic covalent organic frameworks (iCOFs) showed that highly ordered structures provide efficient transport, solving limitations traditional PEO‐based electrolytes. Here, we present imidazolate COFs, PI‐TMEFB‐COFs, having methoxyethoxy chains, synthesized by Debus–Radziszewski multicomponent reactions ionized form, @PI‐TMEFB‐COFs, showing a conductivity 8.81 mS cm −1 transference number 0.974. The mechanism such excellent electrochemical properties is LiClO 4 , making free then those transported through COFs’ pores. @PI‐TMEFB‐COFs formed stable interface with metal. Thus, employing solid electrolyte to assemble LiFePO batteries an initial discharge capacity 119.2 mAh g at 0.5 C, 82.0 % 99.9 Coulombic efficiency were maintained after 400 cycles. These results show iCOFs ether via create new chapter rechargeable
