3D Printed Graphene Aerogel Enhances Supercapacitor Ability

- Nov 02, 2018-

Researchers are using 3D printing to develop supercapacitor electrodes that hold the highest amount of charge per surface area.

A research collaboration from the University of California Santa Cruz and the U.S. Department of Energy's Lawrence Livermore National Laboratory have 3d printed graphene aerogel enables them to develop a porous 3d scaffold loaded with manganese oxide to produce better ultracapacitor electrodes.

Supercapacitors are used as energy storage devices because they charge very quickly - from a few seconds to a few minutes.They also maintain their storage capacity through tens of thousands of charging cycles. Supercapacitors are used in many fields, including regenerative braking systems for electric vehicles.

Supercapacitors made of graphene aerogel/manganese oxide electrodes showed good cyclic stability, maintaining more than 90% of the initial capacitance after 20,000 charge and discharge cycles.
