Abstract As an alternative to bulk counterparts, metal–organic framework (MOF) nanoparticles isolated within conductive mesoporous carbon matrices are of increasing interest for electrochemical applications. Although promising, a “clean” surface is generally associated with poor compatibility and weak interactions metal/ligand precursors, which leads the growth MOFs inhomogeneous particle sizes on outer pore walls. Here, general methodology in situ synthesis eight nanoMOF composites mesochannels high dispersity stability reported. Mesoporous polydopamine (mesoPDA)‐F127 nanospheres unique chemistry, e.g., nanoconfined spaces, catechol functional groups, pyrrolic N doping, hydrophilic PEO blocks, found be suitable molecular platform. Sliced cross‐sectional TEM, HAADF‐STEM, corresponding EDS elemental mapping, as well nitrogen adsorption characterizations, utilized visualize process ZIF‐8 nanoparticles. These careful analyses provides direct evidence that highly dispersed exclusively located inside internal mesochannels. After moderate carbonization mesoPDA‐F127/ZIF‐8 nanocomposites, prototype carbon‐isolated nanostructure achieved, can regulate Zn 2+ plating electrochemistry toward stable aqueous batteries. This first report complete impregnation even dispersion nanoscale interior channels carbons.

Covalent organic frameworks (COFs) are attracting more attention for energy storage applications. COFs possess unique structural properties, such as highly ordered pore structures, abundant functionalization sites, and tunable chemical making them ideal candidates the development of novel materials. In this work, we synthesized sulfonyl two-dimensional (2D) covalent (SLD-COFs) using 4,4'-sulfonyldiphenylamine (SLD). SLD-COFs have a remarkable conjugated structure, which includes imine groups forming large π-bonds, structure can provide consecutive electron conduction paths, enables SLD-COF to transfer charges efficiently, thus improving electrical conductivity. Additionally, introduce redox-active participate in redox process during electrochemical reactions generate pseudocapacitive effect. For current 0.5 A/g, specific capacitance material was 31.5 F/g an acidic electrolyte 41.7 alkaline electrolyte. The flexibility good properties make potentially essential component Meanwhile, retention reaches 78.3% after 1000 GCD cycles at density 1 indicates its cycling stability.

Abstract Rechargeable aqueous zinc‐ion (Zn‐ion) batteries are widely regarded as important candidates for next‐generation energy storage systems low‐cost renewable storage. However, the development of Zn‐ion is currently facing significant challenges due to uncontrollable Zn dendrite growth and severe parasitic reactions on metal anodes. Herein, we report an effective strategy improve performance by leveraging self‐assembly bovine serum albumin (BSA) into a bilayer configuration BSA′s hydrophilic hydrophobic fragments form unique intelligent ion channels, which regulate migration ions facilitate their desolvation process, significantly diminishing anodes leading uniform deposition along (002) plane. Notably, Zn||Zn symmetric cell with BSA electrolyte additive demonstrated stable cycling up 2400 hours at high current density 10 mA cm −2 . This work demonstrates pivotal role self‐assembled protein structures in improving durability batteries.

Abstract The widespread application of aqueous zinc‐ion batteries (AZIBs) is hindered by anode dendrite formation and side reactions, reducing cycling life performance. This study introduces Bi‐Bi₂O₃‐loaded carbon nanofibers (Bi‐Bi₂O₃@CNF) with hierarchical hollow structures surface grooves fabricated via electrospinning, thermal treatment, in situ growth. Experimental characterization density functional theory reveal that the high area fibrous network Bi‐Bi₂O₃@CNF enhance electron transport electrolyte distribution, effectively ohmic resistance concentration polarization. “Spatial Effect” provides ample space for uniform Zn deposition. Additionally, situ‐grown Bi‐Bi₂O₃, pyridinic nitrogen, pyrrolic C─O─Bi bonds induce strong zinc affinity electronegativity, generating an “Electrostatic Confinement amplifies “spatial effect” into a “Dual‐Confinement Effect.” synergy ensures deposition, suppresses dendrites mitigates Compared to pure anodes, reduces polarization overpotential 17.6%, increases hydrogen evolution 11.52%, maintains Coulombic efficiency 98.8% over 200 h.
