High-performance energy-storage architectures from carbon nanotubes and nanocrystal building blocks.

High-performance energy-storage architectures are fabricated by forming conformal coatings of active nanocrystal building blocks on preformed carbon nanotube conductive scaffolds for lithium ion electrodes. This unique structure offers effective pathways for charge transport, high active-material loading, structure robustness, and flexibility. This general approach enables the fabrication of a new family of high-performance architectures for energy storage and many other applications.
