Assembling carbon-coated alpha-Fe2O3 hollow nanohorns on the CNT backbone for superior lithium storage capability

Novel hierarchical nanostructures composed of carbon coated alpha-Fe2O3 hollow nanohorns on carbon nanotube (CNT) backbones have been constructed by direct growth and thermal transformation of beta-FeOOH nanospindles on CNTs, followed by carbon nanocoating. When evaluated as a potential anode material for lithiumion batteries, such hierarchical structures exhibit superior lithium storage capabilities by virtue of their advantageous structural features.
