Inkjet-Printed Graphene for Energy Storage (Printed Electronics and Photovoltaics USA 2011)

Prof Woo Young Lee, George Meade Bond Professor

Dec 01, 2011.

Presentation Summary

  • Discovered that the nanosheets of graphene oxide can be easily inkjet-printed and photothermally reduced to produce electrically conductive, electrochemically stable, and mechanically conformal graphene electrodes.
  • Found that interconnected nanoscale porosity naturally develops within inkjet-printed graphene layers, and is responsible for high surface area (282 m2/g) and high specific capacitance (132 F/g).
  • These findings are being used to fabricate a flexible micro-supercapacitor device in an additive, net-shape manner with minimum use, handling and waste generation using commercially available inkjet printers.
