All-solid-state Battery-Ultracapacitor Hybrid Devices Based on Nanostructured Materials
Agency / Branch:
DOD / ARMY
This project aims to develop all-solid-state hybrid energy storage devices with flexible nanostructured electrode materials combined with a polymer electrolyte. The hybrid devices utilize a capacitor-like electrode based on graphene and carbon nanotubes and a battery-like electrode, comprised of nanostructured LiFePO4 grown on a graphene support. The proposed device combines the advantages of anode, cathode and electrolyte to deliver energy densities>100 Wh/kg, maintain power densities above 1 kW/kg and provide longer life cycle than a typical rechargeable battery. The proposed approach extends to the conformal fabrication of current collectors, electrodes and electrolyte which allow the hybrid devices to be integrated in the next generation of electronic devices.
