Abstract Carbon‐based fibrous supercapacitors (FSSCs) are promising power sources for wearable electronics, often compounding with transition metal oxides (TMOs) to improve energy density. However, conventional methods introducing TMOs onto exterior surfaces of carbon‐based fibers typically degrade electrical transport and cycle stability. Herein, nanoconfined MnO@Mn 2 O 3 heterojunctions within carbon nanotube (CNT) (MOIC) composite FSSCs stabilized by Mn─O─C bonds, exhibiting record stability 95.7% capacitance retention after 10 000 cycles 89.4% 50 reported. X‐ray absorption near edge structure (XANES), diffraction, photoelectron spectroscopy (XPS) analyses confirm heterostructure, which arises through a partial phase transformation from MnO Mn , as further supported density functional theory calculations. chemical verified XPS, extended fine structure, XANES analyses, facilitate 3D electron transport, enabling MOIC fiber superior conductivity than CNT fiber. The nanoconfinement 2+ CNTs, driven capillary effects electrostatic repulsion between protonated CNTs preserves the clean CNTs. This configuration enables successful wet‐spinning three times tensile strength without nanoconfinement. work opens new pathways designing carbon/metal oxide hybridized storage applications.

Abstract The pursuit of high‐energy‐density supercapacitors remains challenged by the irreversible surface charge accumulation and sluggish ion dynamics in conventional vanadate cathodes. To address these limitations, a lattice strain engineering strategy is devised through B/Mo co‐doping NiV 2 O 6 , which enables dynamic regulation distribution via atomic‐level stress manipulation. Density functional theory (DFT) calculations demonstrate that high‐valence Mo 6+ induces compressive (–4.4%) to strengthen metal‐oxygen covalency, while low‐electronegativity B 3+ generates tensile (+ 2.9%) enhances hydroxyl affinity. This dichotomy optimizes OH − adsorption energetics 0.28 eV creates gradient oxygen vacancy. cooperative dopant effects significantly enhance charge‐transfer kinetics, endowing B/Mo‐NiV /NF electrode with superior specific capacitance 2850 F g −1 (1 140 C ) at 1 A . In situ Raman reveals reversible vacancy migration along (004) crystallographic planes during cycling, dynamically dissipates structural stress. solid‐state asymmetric supercapacitor delivers 1.8 V operational window remarkable energy/power density (38.35 Wh kg /900 W 75% capacity retention after 10 000 cycles. Practical viability demonstrated powering 20 parallel‐connected light‐emitting diodes (LEDs). work pioneers strain‐mediated paradigm for durable high‐power energy storage.
