Supercapacitor (Revolution inside?)

damn. Black Swan!

von reddit dazu:

In the comments of this video[1] the PI states that they've achieved energy densities of 1.36mWh/cm3. Since standard energy densities are given in MJ/kg[2] we'll have to guess the mass density 2g/cm3 will be conservative since it is the density of graphite which is very near the highest possible packing density of graphene. This gives us an energy density of .00245 MJ/kg.* Which is 60 times greater than a traditional capacitor (.000 036MJ/kg) but 1/300 the density of a rechargeable lithium ion battery. We can conclude from this that the research is very promising and could have a huge impact in areas where we already rely on large capacitors. But the technology is not any where near replacing current battery technology. * Side work: 1.36mWh/cm3 * .5 cm3 /g * 3600 s/h = 2448 Ws/kg = 2.45 kJ/kg Note: 2g/cm3 is the most conservative mass density estimate but every where I checked only gave the density in terms of cm3. I would not be surprised if their actual prototype had a density closer to 1g/cm3 but I doubt it would be much less than that.

vielversprechend sicher, wohl aber erstmal nicht komplett Weltbewegend.

Das besondere dabei ist das es sich mit lithium-ionen batterien verbinden lässt um so hohe Energiedichte und hohe Ionenbeweglichkeit (~= ladegeschwindigkeit) zu erhalten.

Das wurde bereits for etwa einem Jahr entdeckt, also hoffentlich ist ist nichtmehr alzu lange bis solche Batterien aufm markt kommen
