3D nanocomposite architectures from carbon-nanotube-threaded nanocrystals for high-performance electrochemical energy storage.

Better electrode architecture: spherical assemblies of electrochemically active nanocrystals threaded with carbon nanotubes are made using a simple solvation-induced-assembly process. This architecture provides the composites with mechanical robustness, effective ion- and electron-transport pathways, enabling the fabrication of electrodes with high rate, high capacity, and long cycling stability.
