Iron oxides, such as hematite (α-Fe2O3), maghemite (γ-Fe2O3), and magnetite (Fe3O4), have been considered as alternative anode materials for lithium-ion batteries (LIBs) due to their high theoretical capacity, abundant reserves, low cost, and non-toxicity. However, their practical application has been hampered by the large volume expansion, which leads to rapid capacity fading. Nanostructure engineering has been demonstrated to be an effective avenue in tackling the volume variation issue and boosting the electrochemical performances. Herein, recent advances on nanostructure engineering of iron oxides for lithium storage are summarized. These nanostructures include 0D nanoparticles, 1D nanowires/nanorods/ nanofibers/nanotubes, 2D nanoflakes/nanosheets, as well as 3D porous/hollow/hierarchical architectures. The structureelectrochemical performance correlations are also discussed. It is believed that the performance optimization strategies summarized here might be extended to other high-capacity LIB anode materials.

“…In particular, in situ technology has been developed to observe directly the electrochemical behavior of the electrode materials in order to reveal their reaction mechanism [3,4]. Transition metal oxides are promising anode materials for LIBs owing to their high theoretical capacities and volumetric energy densities [5][6][7]. However, their applications have been hampered by the poor capacity retention upon cycling due to large volume expansion and severe particle aggregation during the Li ?…”

Porous Co 3 O 4 microrods have been prepared by an ultrasound-assisted route with subsequent calcination. The as-prepared Co 3 O 4 microrods are composed of interconnected nanoparticles with porous characteristics. The ultrasonic irradiation is critical to determine the morphology and the electrochemical performance of the products. When tested as anode material for lithium-ion battery, the porous Co 3 O 4 microrods show improved capacity and rate cycling performance. The reversible capacity of the materials retains 678 (±5) mAh g -1 after 50 cycles at 100 mA g -1 . Even when cycled at various rate for more than 50 cycles, the reversible capacity recovers to 600 (±5) mAh g -1 for the current of 100 mA g -1 . The improved lithium-storage performance can be attributed to the reduced electrochemical reaction resistance due to the unique porous architecture of Co 3 O 4 microrods.

SUPPLEMENTARY NOTES ABSTRACTThe effort is a result of team work from the collaboration of Prof Kofinas (PI), Prof. Piao of Seoul National University, Korea and Prof. Begin-Colin of University of Strasbourg, France. It is desirable for a dielectric material of an RF antenna to have the highest possible permeability for the scaling factor, and lowest possible magnetic loss for the radiation efficiency. To reduce the dielectric loss, and achieve high permittivity and permeability at the frequency range of 1 MHz-1 GHz, the PI was able to assemble corona magnetite Nanoparticles successfully. The permeability values achieved by composites made from collectively assembled corona magnetite nanoparticles are significantly higher than the existing magnetite-polymer composites and magnetite-PDMS composites. Additionally, the composites prepared with collectively assembled corona magnetite nanoparticles exhibit an extraordinary magnetic resonance, which changes with the particle size of magnetite nanoparticles. The PI will continue to develop composites that could be utilized for developing highbandwidth radio frequency antennas. SUBJECT TERMS
