Graphene based supercapacitor about to revolutionize energy storage

Through it’s fractal structure 1 gramm of this material has a surface area of 2630m²
which compared to the human lung with astounding 50-100m² surface area is really  incredible!

This huge step will bring Moores Law to energy storage!

  1. Nice video. It doesn’t really cover however how the fractal detail of this surface is created to generate such high yields. Capacitors generally require a dielectric layer in order to separate charged plates. Electrolytic capacitors use metal film oxide layers to create these barriers, which are much thinner than traditional materials but very fragile. A reverse charge will break down the oxide resulting in hotspots within the capacitor resulting in current leakage and in some cases the release of stored energy can cause violent catastrophic failure of the part (explosion).

    A fractal surface to be suitable for capacitor storage must have a rough surface (the more surface roughness, the greater the surface area) combined with a small coating of insulating material with a high resistance and dielectric strength. It appears based on the video that the “graphine oxide” serves a similar function to metal oxide in traditional electrolytics. But oxides of carbon (monoxide and dioxide) are gasses so I am confused as to how the barrier works on a molecular level.

  2. Not sure how the superconductor article relates to the graphene capacitor. Also 2010 is somewhat old. I imagine graphene will have some resistance due to being carbon based. But I’m more curious how the barrier works. I imagine like electrolytic capacitors it will need a conductive liquid to get at the fractal surface at a molecular level. Certainly more efficient than current foil based super-capacitors, which exhibit extremely smooth flat surface. A capacitor with enough electron storage to hold a battery like charge would be something. But the reason why batteries hold much energy is that electrons travel through the medium as reversible chemical changes take place. A capacitor by nature has a barrier preventing current flow across it.

    Either way, it may be several years before these new capacitors reach market, and longer still before they are manufactured cheaply enough to have practical application in consumer tech.

  3. Oh, sorry stardust – this happens when you only read the headlines in a hurry. I had misread superconductor/capacitor.

    1. you’re totally right – and usually I do read and try to really understand before I post stuff!
      But I’m drowning in work to finish this site on time, so I can’t dive as deep into single topics or discussions as they deserve right now. But this will definitively become better. Sorry again.. 😉
