“…The discharge capacity of Co 3 O 4 /MnO 2 @C is lower than that of Co 3 O 4 /MnO 2 and Co 3 O 4 in the initial 20 cycles. It may be due to the addition of carbon and the reduction of specific surface area of the carbon coating . The Co 3 O 4 /MnO 2 @C electrode maintains a reversible capacity of 306 mAh g −1 after 200 cycles, which shows a stable cycling performance and the Coulombic efficiency of Co 3 O 4 /MnO 2 @C electrode is higher than 97% after the tenth cycle onward.…”

This study presents a general approach for the synthesis of carbon-encapsulated wire-in-tube Co 3 O 4 /MnO 2 heterostructure nanofibers (Co 3 O 4 /MnO 2 @C) via electrospinning followed by calcination. The as-synthesized Co 3 O 4 /MnO 2 @C is investigated as the sodium-ion batteries anode material, which not only exhibits a high reversible capacity of 306 mAh g −1 at 100 mA g −1 over 200 cycles, but also shows a cycling stability of 126 mAh g −1 after 1000 cycles at a high current density of 800 mA g −1 . The excellent electrochemical performance can be ascribed to the contribution from carbon-encapsulated outer-tube Co 3 O 4 and inner-wire MnO 2 heterostructures, which offer a large internal space and good electrical conductivity. The present work can be helpful in providing new insights into heterostructures for sodium-ion batteries and other applications. Electrospinning

[59,60] Some articles have studied metal alloys, silicon, transition MOs, and chalcogenides (selenide) as anodes with superior capacity to replace graphite in LIBs.

batteries, sodium-selenium (Na-Se) batteries, Li-tellurium (Li-Te) batteries, and Na-S batteries) have their own distinctive applications due to their various characteristics. To explore new materials with high performance, large studies have been devoted to the development of nextgeneration batteries.Porous carbon (PC) materials possess many unique properties due to their large surface areas, high conductivity, large pore volumes, high thermal stability, and surface functionalities, [22][23][24] leading to their wide use in energy storage and conversion. Traditionally, PC can be obtained via various methods, such as the direct heat treatment of organic precursors, hard template or nanocast methods, and soft template methods. However, the production of PC from these methods cannot be scaled-up because of certain barriers (disordered structure with wide size distributions, complicated processes, etc.). [23,25,26] Metal-organic frameworks (MOFs) have drawn wide research interest as a novel class of porous materials that are crystalline materials consisting of metal ions and organic ligands. [4,21,[27][28][29][30][31] Since the report on the MOF-templated synthesis of PC in 2008, [32] a large number of studies have been reported on the use of MOFs as suitable precursors/templates for carbon synthesis. [22,26,[33][34][35] At present, a large number of studies indicate that zeolitic imidazolate framework-8 (ZIF-8), MOF-5, MIL-125 (Ti) (MIL = Materials of Institute Lavoisier), and ZIF-67 with excellent thermal stability and unique porous structures are the more commonly used MOF precursors (Scheme 1). [3,36,37] All of them, ZIF-8, possessing nitrogen-containing ligands, has high porosity and thermal stability. [38][39][40] MOF-5 possesses excellent thermal stability, high porosity, and so on. [41] MIL-125, an active photocatalyst, includes cyclic octamers of TiO 2 octahedra. [42,43] ZIF-67 has a tunable pore aperture, highly stable structure, and catalytic activity. [37,44,45] The above-mentioned MOFs have been widely used for gas adsorption, molecular separation, catalysis, batteries, supercapacitors, and so on. [13,14,33] Moreover, carbon hybrids containing nanostructured metal species (e.g., metal oxides (MOs)) are likely to form under in situ carbonization conditions. [46] Compared with the carbonaceous materials from conventional precursors, MOF-derived carbon materials have significant advantages with high specific surface areas, tailorable porosities, unique morphologies, and easy functionalization with other heteroatoms. [14,23,31] For example, Xu and co-workers [47] obtained 1D carbon nanorods via the pyrolysis The applications of carbon and carbon-based materials with high porosity, high surface area, and functionalities based on metal-organic framework precursors and/or templates have attracted significant research interest in recent years, particularly in the field of batteries. The chemical and physical properties of carbon and carbon-based materials obtained by the heat treatment of various metal-organic ...

Carbon‐coated magnesium ferrite (MgFe2O4@C) nanofibers were synthesized by electrospinning technology and a subsequent carbonization process using polydopamine as carbon precursor. SEM and TEM observations revealed that N‐doped carbon layers with different thicknesses were coated uniformly on the surface of the MgFe2O4 nanofibers. If used as anode materials for lithium–ion batteries (LIBs), MgFe2O4@C nanofibers with a carbon thickness of 7 nm exhibited an excellent cycling performance and rate capability compared with pristine MgFe2O4 and MgFe2O4@C nanofibers with carbon thicknesses of 4 and 15 nm, respectively. These nanofibers delivered high initial discharge and charge capacities of 1383 and 1044 mAh g−1, respectively, with a Coulombic efficiency of 75.5 %. A reversible capacity of 926 mAh g−1 could be obtained after 200 cycles at 0.1 Ag−1. Even at a high rate of 1 A g−1 after 500 cycles, they still maintained a stable capacity of 610 mAh g−1 with a capacity retention of 81.9 %. Therefore, the MgFe2O4@C nanofibers are a potential anode candidate for LIBs.
