Nanofibrils Carbon Electrode for Rechargeable Batteries

Graphite carbon electrodes have been used as the anode in recently commercialized rechargeable lithium batteries. However, the energy densities achieved to date for secondary lithium batteries have fallen far short of the theoretically attained mark. The specific energy or capacity of the Li-ion system, and for the anode process in particular, the Li intercalation efficiency, and the irreversible capacity associated with the first charge process, depends largely on the microstructure of carbon materials used. This program seeks to leap-frog these technology barriers with an innovation that focuses on nano-precision engineering nanofibrils carbon as anode materials. During Phase I, NRC will demonstrate the proof-of-concept of such a material. Phase II will build on Phase I success, optimize, build prototypes and field test the technology in partnership with AF. Phase III will commercialize the technology and anaticipated spin-off.
