“…Superparamagnetic monodisperse Fe3O4/GO nanocomposite has been synthesized by a facile one-pot solvothermal synthesis using FeCl3·6H2O as the iron resource, EG as the reaction solvent, NaHCO3 as the precipitant and adding a GO suspension to EG solvent [55]. Nanocomposites with ultra-small magnetite (Fe3O4) NPs (~3 nm) uniformly anchored on RGO nanosheets have been successfully synthesized for anodes in sodium-ion batteries by a novel single-step high-temperature coprecipitation approach [56]. An in situ synthesis of very small MNPs (<12 nm) on the surface of graphene sheets has been achieved through the direct, liquid-phase exfoliation of crystalline graphite and the subsequent chemical functionalization of the graphene sheets via the well-established 1,3-dipolar cycloaddition reaction [57].…”

“…In the initial cathodic scan, two peaks are observed at 1.10 and 0.38 V, respectively. The peak around 1.10 V corresponds to Na + insertion into Fe 3 O 4 to form Na x Fe 3 O 4 ,, . And the peak at 0.38 V is assigned to the reduction of the Fe 3 O 4 to Fe.…”

Iron oxide (Fe3O4) is considered as a promising sodium ion anode material due to high capacity, low cost and nontoxic features. However, the main challenges associated with Fe3O4 anodes are structure instability and low initial Coulombic efficiency (∼50%) during charge/discharge process. In this work, thin carbon layer (∼2.5 nm) coated porous Fe3O4 particles (∼ 100 nm) anchored on reduced graphene oxide sheets (Fe3O4@C/rGO) are achieved. Fe3O4@C/rGO composite shows a stable cycling performance of 356 mAh g−1 after 300 cycles at 0.1 A g−1 with a slight decay of 0.098 mAh g−1 per cycle. Moreover, it exhibits a high initial Coubombic efficiency of 74%, superior to the values in most reported literatures for Fe3O4/carbon composites. The excellent electrochemical performance is attributed to the porous structure of Fe3O4 which can accommodate the mechanical stress induced by the volume expansion, and the outside carbon layers which can protect Fe3O4 from electrolyte to form a stable solid electrolyte interface film.

“…Transition‐metal oxides and sulfides, both of which generally have large volume expansion, are also studied for SIB, in which nanoscale carbon materials are useful as the structural stabilizer and electrical conductivity additive. In one example, ultrafine Fe 3 O 4 nanoparticles were uniformly distributed on rGO surface and used as SIB anode (Figure a) . The composite shows excellent cyclability (98 % capacity retention after 200 cycles), although the reversible capacity is low (204 mA h g −1 ).…”

Hybridization of different electrode materials to yield favorable synergistic effects and enhanced function is a focus of current research in developing advanced electrochemical energy‐storage devices. This Focus Review summarizes recent progress in rational design and fabrication of advanced electrode materials with heterogeneous nanostructures and interfaces engineered on the nanometer scale. The hybridization typically involves two or more materials such as metal oxides (or sulfides, carbides, and nitrides) and various forms of nanostructured carbon materials. We focus on two devices: sodium ion batteries and supercapacitors, as well as their integration with other devices to realize multifunctional systems.
