  • Graphical abstract: Nanosized porous {alpha}-Fe{sub 2}O{sub 3} powder was successfully synthesized via the molten salt method. Electrochemical measurement results demonstrated that the electrode properties of the {alpha}-Fe{sub 2}O{sub 3} could offers excellent cycling performance and high rate capability. The capacity of the product shows two different trends during cycling which are rarely reported in the literature, a decrease in capacity in the first 100 cycles and an increase afterwards up to 600 cycles, with the lowest and highest capacity around 970 and 1972 mAh/g, respectively. Research highlights: {yields} Nanosized {alpha}-Fe{sub 2}O{sub 3} as an anode material for lithium-ion battery. {yields}more » The nanosized {alpha}-Fe{sub 2}O{sub 3} shows excellent electrochemical performance and exhibits the feature of capacity increase upon cycling. {yields} The porous rhombohedral structures of {alpha}-Fe{sub 2}O{sub 3} could provides the short Li{sup +} diffusion length, decreases the traverse time for electrons and Li{sup +} ions, and reduces the volume expansion to some extent. {yields} The cubic structure of {alpha}-Fe{sub 2}O{sub 3} has been modified to a needle-like structure after prolonged cycling. -- Abstract: We report a simple molten salt method to prepare nanosize {alpha}-Fe{sub 2}O{sub 3}, as well as its electrochemical performance as anode material for lithium ion batteries. The structure and morphology were confirmed by Raman spectroscopy, X-ray diffraction, and transmission electron microscopy. The as-prepared {alpha}-Fe{sub 2}O{sub 3} is a rhombohedral phase of hematite with crystal size in the range of 20-40 nm. The electrochemical measurements were performed using the as-prepared powders as the active material for a lithium-ion cell. The nanosized {alpha}-Fe{sub 2}O{sub 3} shows excellent cycling performance and rate capability. It also exhibits the feature of capacity increase upon cycling. The outstanding electrochemical performance of the {alpha}-Fe{sub 2}O{sub 3} can be related to several factors, namely, the short Li{sup +} diffusion length along the porous rhombohedral structures and the nanosized nature of the materials, which decreases the traverse time for electrons and Li{sup +} ions, and reduces the volume expansion to some extent during charge/discharge reactions.« less
  • Room temperature sodium-ion batteries are of great interest for high-energy-density energy storage systems because of low-cost, natural abundance of sodium. Here, we report a novel graphene nanosheets-wrapped phosphorus composite as an anode for high performance sodium-ion batteries though a facile ball-milling of red phosphorus and graphene nanosheets. Not only can the graphene nanosheets significantly improve the electrical conductivity, but they also serve as a buffer layer to accommodate the large volume change of phosphorus in the charge-discharge process. As a result, the graphene wrapped phosphorus composite anode delivers a high reversible capacity of 2077 mAh/g with excellent cycling stability (1700more » mAh/g after 60 cycles) and high Coulombic efficiency (>98%). This simple synthesis approach and unique nanostructure can potentially extend to other electrode materials with unstable solid electrolyte interphases in sodium-ion batteries.« less
