“…In the attempt to improve the electrochemical performance of TiO2 (theoretical capacity 335 mAh g -1 ) for practical applications, hierarchical TiO2-B nanowire@a-Fe2O3 nanothorn corebranch arrays have been recently prepared by a stepwise hydrothermal approach [69]. Fe2O3 was chosen to cover the TiO2 nanowires due to its high theoretical capacity of about 1000 mAh g -1 that could contribute significantly to increase the overall capacity of the hybrid structure.…”

Tailoring Iron Oxide Nanostructures for High-Capacity Lithium Storage

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.

“…Because rational morphological design of active materials can relieve internal stress caused by volumetric expansion and thus protect the microstructure from collapse during the diffusion of ions. Moreover, minimizing particle sizes can shorten the diffusion distance of lithium ions and the electronic transportation distance [16,17]. To date, var-ious SnS 2 hierarchical microstructures with different morphologies, such as microflowers [18], microspheres [19], microplates [10] and microbelts [20], were synthesized to improve the electrochemical properties.…”
