“…Lithium-ion batteries (LIBs), , which play an essential role as important energy storage devices, have greatly facilitated the development of new energy vehicles, intelligent electronics, and other devices − as a result of their merits of high energy density, stable cycling property and good ecological friendliness − and also effectively alleviated the energy crisis and environmental deterioration . However, it is difficult for the commercial graphite anode with a low theoretical specific capacity (372 mA h·g –1 ) to satisfy the requirements of large capacity and high energy density in the new era of carbon peak and carbon neutralization, − especially in the field of power batteries .…”

Iron-based compounds, which feature the advantages of high specific capacity and inexpensive fabrication, are widely studied as promising anode candidates for the purpose of facilitating their electrical conductivity and structural integrity. Interface engineering and structural confinement are verified as effective methods to improve the sluggish charge transfer kinetics and rapid structural failure during the repeated lithiation/delithiation processes. In this work, we proposed a simple synthesis strategy to construct a space-confined Fe3O4/FeS heterostructure embedded in pyrolytic carbon (Fe3O4/FeS@C). The Fe3O4/FeS heterogeneous interface facilitates combination of the advantages of each component (Fe3O4 and FeS) and constructs a built-in electric field to promote the charge transport in the Fe3O4/FeS@C anode. The space-confined structure contributes to maintaining the structural stability by buffering the volumetric variation and suppressing the aggregation of active particles. Profiting from the synergism of the engineering of heterogeneous interfaces and the feature of confined structure, Fe3O4/FeS@C manifests an excellent rate capability (913.74 mA h·g–1 at 200 mA·g–1 and 535.79 mA h·g–1 at 6400 mA·g–1) and a stable cycling performance (439.8 mA h·g–1 after 1000 cycles at 3200 mA·g–1) as a competitive anode for lithium-ion batteries. The density functional theory (DFT) calculations demonstrate that the introduction of a heterogeneous interface enhances the adsorption of Li-ions, improves the electrical conductivity, as well as promotes interfacial electron/ion transfer kinetics.

Lithium‐ion batteries (LiBs) are one of the most promising energy storage devices. However, the large‐scale application of LiBs is limited by their electrochemical properties. In this study, we built a three‐dimensional (3D) conductive network structure with carbon and 3DG coating VPO4 (VPO4@C@3DG) via a one‐pot hydrothermal method with subsequent high‐temperature annealing. The effects of the content of three‐dimensional porous graphene (3DG) on the crystal structure, morphology, and electrochemical properties of VPO4/C are investigated using characterization and electrochemical test techniques. The SEM images show that the size of sphere‐like particles of VPO4@C@3DG composite with 20 wt.% of 3DG (VPO4@C@3DG‐20) is the smallest in all samples. In addition, the electrochemical experimental results reveal that VPO4@C@3DG‐20 exhibits the best cycling and rate performance compared to other VPO4@C@3DG composites. Specifically, VPO4@C@3DG‐20 achieves an initial charge capacity of 601.2 mAh g−1 at 0.2 C (110 mA g−1) and keeps at 354 mAh g−1 at the 100th cycle. This is because the introduction of 20 wt.% 3DG graphene inhibits the growth and aggregation of the particles, thus shortening the diffusion path of Li+. In addition, the 3D conducting network structure boosts the conductivity of the materials and buffers the volume variation resulting from the charging/discharging process.
