Abstract Carbon Nanofibers (CNFs)/transition metal oxides (TMOs) composites have obtained much attention as supercapacitor electrode with benefits from the superior electrical conductivity of carbon materials and high capacity TMOs. However, nano-size TMOs is prone to agglomeration hard grow efficiently uniformly on CNFs due surface lack effective targets, which limits its performance. In this paper, different hierarchical structures CNFs-NiCo2O4 were prepared assembled electrode. The results showed that by treatment potassium permanganate exhibited a capacitance 1175 F g− 1 at current density 1 A long-term cycling stability, 93% retention after 3000 cycles. excellent electrochemical performance could be attributed more active sites introduced solvent treatment, beneficial for NiCo2O4 CNFs. This approach provides new strategy controllable design synthesis homogeneous CNFs/TMOs composites.

Abstract Spinel LiMn 2 O 4 is a promising cathode material for lithium‐ion batteries (LIBs) due to its nontoxicity, resource abundance, substantial operating voltage, and remarkable thermal stability. Nevertheless, subjected subpar electronic/ion conductivity continuous capacity attenuation triggered by the Jahn‐Teller distortion. In this regard, metal‐organic frameworks (MOFs) are potential morphological controllers that impact particle size crystal orientation offer vacancy‐accepting layers facilitate oxygen defect formation, which boost electron/ion diffusion when utilized as self‐sacrificial templates. The dissatisfying retention caused Mn 2+ dissolution related 3+ disproportion another tricky issue, requires resolution through surface modification. To attain these goals, work develops strategy intermarrying merits of defects Zn‐based zeolitic imidazolate framework‐62 (Zn‐ZIF‐62) glass shields. Mn‐MOFs with carboxyl‐based ligands possessing various coordination numbers adopted precursors optimize feature modulate vacancy level. Computational experimental results examine efficaciousness in ameliorating electrochemical activity expediting transportation. Synchronously, ZIF‐62 layer inhibits manganese loss phase degradation toward prolonged cycling durability LIB half/full cells. This study envisions versatile methodology modify spinel longevous next‐generation LIBs.
