Novel hollow iron oxide nanoparticles with a high concentration of defects were synthesized by Center for Nanoscale Materials (CNM) facility users from Argonne's Chemical Sciences & Engineering Division and Advanced Photon Source (APS), and the University of Chicago, working collaboratively with the CNM NanoBio Interfaces Group. A new concept of electrode fabrication based on sealing nanoparticles between layers of pure carbon nanotubes was also developed. When this novel electrode was used as a cathode, the inherent iron vacancies allowed for significantly increased performance in a lithium-ion battery.
