Design and fabrication of effective electrode structure is essential but is still a challenge for current lithium-ion battery technology. Herein we report the design and fabrication of a class of high-performance robust nanocomposites based on iron oxide spheres and carbon nanotubes (CNTs). An efficient aerosol spray process,combined with vacuum filtration Was used to synthesize such composite architecture, where oxide nanocrystals were as sembled Into a continuous carbon Skeleton and entangled In Porous CNT networks. This material architecture offers many critical features that are required for high-performance anodes, including efficient Ion transport, high Conductivity, and structure durability, therefore enabling an electrode with outstanding lithium storage performance. For example, such an electrode with a thickness of similar to 35 mu m could deliver a specific capacity of 994 mA h g(-1) (based on total electrode weight) and high recharging rates. This effective strategy can be extended to construct many other composite electrodes for high-performance lithium-ion batteries.
