Fe3O4@C spheres were synthesized by hydrothermal reaction at 190°C followed by a low temperature heat annealing at 600 °C and applied as an anode material for lithium-ion batteries. The samples were characterized by XRD and SEM. The electrochemical performances of as-synthesized Fe3O4@C were systemically investigated. A reversible capacity of 873 mAh g-1 is obtained in the second cycle at 400 mA g-1. More importantly, the discharge specific capacity can still maintain at about 767 mAh g-1 after 80 cycles. Moreover, Fe3O4@C spheres electrode shows satisfactory rate capability even at a rate up to 2000 mA g-1. Thus, the results demonstrate that Fe3O4@C spheres show encouraging application potential to be an advanced anode material for lithium storage

In this report, the porous Fe3O4/C nanocomposites were successfully synthesized by using ferrocene as raw material and dilute nitric acid as solvent via extremely convenient and low-cost one-step calcining method. The formation of porous structure resulted from the aggregation and assembly of numerous nanoparticles. The experimental results show that the crystallinities, morphologies and electrochemical performance of samples were affected by the calcining temperature and carbon content. As an anode for lithium-ion batteries (LIBs), the Fe3O4/C nanocomposites obtained at calcination temperature of 500∘C (Fe3O4/C-a500) exhibited remarkable initial specific discharge capacity of 1418[Formula: see text]mA[Formula: see text]h g[Formula: see text] and a reversible capacity retention of 721[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text] after 100 cycles at the current density of 100[Formula: see text]mA[Formula: see text]g[Formula: see text]. The excellent properties can be attributed to the high theoretical capacity of Fe3O4, the high conductivity of carbon and especially the porous structure, which offered more sites for the storage and insertion of Li ions. Even at the current density of 1000[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text], the reversible capacity of Fe3O4/C-a500 can be up to 291[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text], indicating the prepared typical nanocomposite presented excellent electrochemical performances and lithium storage capacity, which may be a promising candidate as the anode material for LIBs.

Hierarchical flower-like Ni3V2O8/Co3V2O8 composites were prepared by a simple one-step hydrothermal process. When employed as an anode for lithium-ion batteries (LIBs), the fabricated Ni3V2O8/Co3V2O8 composites exhibited significantly improved lithium storage performances with superior discharge capacity (1142.7[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 100[Formula: see text]mA[Formula: see text]g[Formula: see text]), excellent cycling stability (933.2[Formula: see text]mAh[Formula: see text]g[Formula: see text] after 600 cycles at current density of 500[Formula: see text]mA[Formula: see text]g[Formula: see text]) and remarkable rate capability (607.6[Formula: see text]mAh[Formula: see text]g[Formula: see text] even at rate of 5000[Formula: see text]mA g[Formula: see text]). The superior electrochemical properties could be attributed to the hierarchical flower-like structure and impressive synergistic interplay between Ni3V2O8 and Co3V2O8, which resulted in improved electronic conductivity and stable mass transfer. This interesting hybridization strategy might open a new avenue to prepare micro/nanostructured composites for high-performance energy storage devices.
