Abstract In this study, a straightforward and environmentally benign solvothermal method for synthesizing hollow square‐tubular polyimides (HST‐PIs) is introduced. The process utilizes 1,4,5,8‐naphthalenetetracarboxylic anhydride urea as reactants, replacing traditional toxic organic solvents with water ethanol. This investigation explores the effects of various reaction conditions, such water‐to‐ethanol volume ratio, time, temperature, on product morphology, resulting in distinct structures like sheets, columns, layers. Notably, are synthesized under specific conditions: 2:1 24 h 200 °C temperature. study attributes self‐assembly to three primary non‐covalent interactions: hydrogen bonding, π–π stacking, hydrophobic interactions. gel permeation chromatography (GPC) analysis indicates that PIs molecular weight predominantly ranges from 10 000 15 000. As an electrode material, square tubular exhibit initial discharge capacity 297.9 mAh·g −1 at current rate 0.1 C, coulombic efficiency 79%. After ten cycles, improves 97% maintains above 98% subsequent cycles. presents innovative friendly polymers.

Abstract The low energy density and safety problems of lithium‐ion batteries based on liquid electrolyte have set off a new wave high specific capacity battery design to meet the need future market. Solid‐state lithium metal has been widely concerned for its density, safety, electrochemical stability. Especially, polymer‐based solid‐state electrolytes (polymer SSEs) attracted much attention due good interfacial contact, flexible mechanical properties, physical/chemical However, deficiencies ionic conductivity weak strength limit further development polymer SSEs. Here, hybrid ceramic–polymer composite (CSSEs), specifically consisted polymers inorganic ceramic active fillers, can achieve conductivity, excellent Li dendrite growth inhibition. Based intrinsic characteristics polymers, this review expounds strategies improve performance CSSEs. screening modification fillers in recent years, including structural design, surface modification, interface engineering, are reviewed. Finally, core ideas existing designs, proposed feasible solutions, aiming at providing industrialization CSSEs summarized.

Polymer-based electronic devices are limited by slow transport and recombination of newly separated charges. Built-in electric fields, which arise from compositional gradients, known to improve charge separation, directional transport, reduce recombination. Yet, the optimization these fields through rational design polymeric materials is not prevalent. Indeed, polymers disordered generate nonuniform that hard measure, therefore, optimize. Here, we review work focusing on intentional in systems with applications catalysis, energy conversion, storage. This includes chemical tuning constituent monomers, linkers, morphology, etc. result stronger molecular dipoles, polarizability or crystallinity. We also techniques characterize emerging processing strategies based fields. These studies demonstrate benefits optimizing polymers. However, often restricted scale, deriving new pendants on, linkers between, monomers. does always translate strong at polymer level, because they strongly depend monomer orientation. A better control morphology monomer-to-polymer scaling relationship therefore crucial enhance materials.

Due to the advantages of large interstitial sites, antisolubility, and reversible insertion extraction anions, polypyrrole (PPy) has become an excellent P-type electrode material for dual-ion batteries. Unfortunately, PPy electrodes inevitably suffer from low specific capacity poor cycle stability because structural disintegration during repeated cycling as well doping ability brought on by aggregation or cross-linking within chain. In this work, with different proportions coupling mode (α-α, α-β, β-β coupling) was derived preparation methods. Among them, interfacial frozen polymerization method (I-PPy) is dominated α-α possesses best anion highest 119 mAh g
