Electrochemical energy storage (EES) devices are much needed due to their improved reliability and sustainability. As a class of EES, supercapacitors (SCs) have exhibited relatively more advantages, including high power density, longer cycle life, rapid charge-discharge speed, efficiency. Carbon materials the electrodes most significant concern in high-performance SCs. Among carbon materials, electrospun-derived nanofibers (CNFs) composites interest scalable preparative process, specific surface area (SSA), porosity, apt construct essentially conducting self-standing for EES leading electrochemical performance capacitance. Conducting polymers (CPs)-based can be used as SCs' versatility, supreme conductivity, redox property, inherent elasticity, low cost, facile production. This review aims provide precise overview recent trends CPs, especially concentrating on polyaniline (PANI), polythiophene (PTh), polypyrrole (PPy), poly (3,4-ethylene dioxythiophene) (PEDOT) based electrospun CNFs composite potential flexible The systematically addresses synthesis techniques, design concepts, progress, challenges, future perspectives developing binder-free, CPs-derived CNFs/composites-based constructing

Abstract Rechargeable aluminum‐sulfur batteries (Al‐S) are emerging as a promising alternative energy storage system beyond lithium‐ion due to their high density, abundant material resources, and economic efficiency. However, practical application remains challenged by sluggish conversion kinetics, polysulfide shuttling, low sulfur cathode utilization. While extensive studies have focused on enhancing adsorption through catalytic strategies, the roles of electronic structure in dictating performance remain underexplored. Here, this work unveils critical effect unpaired single atom ferromagnetic transition metals systematic evaluation three typical atomically dispersed atoms—Fe, Co, Ni—supported porous carbon (denoted PC‐SAFAs). Comprehensive characterizations density functional theory (DFT) calculations reveal that PC‐SAFe catalysts, exhibiting highest spin polarization arising from electrons, demonstrate strongest interactions with polysulfide, thereby facilitating rapid reversible reactions. Consequently, Al‐S incorporating optimized achieve an impressive specific capacity 508.8 mAh g −1 at 1.0 A after 500 cycles, along much improved rate capability. This provides deeper understanding role chemistry, offers new insights for developing high‐performance batteries.

Abstract Nickel titanate (NiTiO 3 ) nanostructured materials have gained extensive attention in the field of lithium‐ion batteries (LIBs) due to their high theoretical capacity and low cost. However, NiTiO exhibits conductivity significant volume changes during cycling, resulting decay poor cycling stability. Herein, we propose a feasible strategy enhance performance nanostructures by adjusting morphology. By manipulating choice solvent employed synthetic process, obtain microbars (NTO MBs) through self‐assembly nanoparticles NPs). When utilized as an anode material LIBs, NTO MBs exhibit 410 mAh g −1 after 200 cycles at 100 mA , surpassing that NPs (212 ). The improved is attributed unique porous bar‐like structure, composed numerous NPs, which provides substantial storage space for Li + ions owing its larger specific surface area. Additionally, structure accelerates diffusion electron transfer. To gain profound understanding enhanced morphology adjustment, conduct comprehensive investigation on growth mechanism MBs. This work valuable insights into governing control MBs, facilitating rational design synthesis tailored with LIBs.
