Make a supercapacitor with a DVD writer

Professor Kaner from UCLA demonstrates how to build a high-performance graphene-based supercapacitor with a DVD writer [PDF!]. The process uses a DVD writer to burn a pattern onto a plastic film coated with graphene. The resulting supercapacitor is flexible, and capable of storing enough energy to drive an LED for a few minutes.

There has been a video going around from researchers at UCLA about building super capacitors using a Lightscribe DVD writer and graphite oxide (GO), which I think looks really amazing and am interested in reproducing. I figured others might be as well so here is what I know so far.

Nabit started reverse engineering the process and left his research in the forum. Anyone interested in a home brew a supercapacitor?

  1. It would be nice if the numbers or the chart with the volumetric and areal capacitance was present in the article. Had to go look for it in the linked pdf-document.

    (Numbers are for all-solid state LSG electrochemical capacitor and dependent on current density.)

    Volumetric Stack Capacitance in FARAD/CM³ (not milli- or microfarad)
    ranges between 0.2 to 0.6 F/cm³

    Areal capacitance in mF/cm² (it’s in millifarad)
    ranges between 1 and 3.5 mF/cm²


    This is amazing!!
    Hopefully this becomes available as quick as possible, and very, very cheap:).
    Would really like have these in cheap, small, light and efficient power supplies.
