    Scientists see the light on graphene microsupercapacitors.

    I thought they'd been named as nanohypercapacitors. One of us is lagging behind the curve.

    Just because my Christmas has gone totally pear shaped, doesn't mean I should stop trying to educate Andrew.

    Physicists develop graphene material for a more efficient energy storage.

    Compliments of the season every one.

    Yo dude! Glad to see you back. Hope it isn't quite as bad as it sounds. I have declared Christmas a non-event for personal reasons btw.

    The article gave me some general ideas which I'll post shortly. Fixed link

    Welcome back Trim! Nice to see you back here.

    It turns out that the energy density (J/m3) of a capacitor with a dielectric can be expressed in a way that's independent of the capacitor geometry, and depends only on the dielectric properties, like so:
    C = ε0 εr A / d [Farad]
    U = 1/2 C v2 [Joule]
    V = A d [ m3 ]
    E0 = v0/d [volt/m] (max field)
    so
    U/V = ε0 εr E02 [J/m3]

    So the critical field is the most important parameter, followed by the dielectric constant.

    The linked article blurts "They exhibit a very high dielectric constant of 753".
    Er, no. A "high k" is found in stuff like BaTiO3 with k above 10,000.
    Therefore Fail.

    Is the critical field specified? Buggered if I can find it.
    Therefore Fail.

    The article is titled "Physicists develop graphene material for a more efficient energy storage."
    Only trouble is that we don't know what it is.
    King Useless.

    Why do people make me angry? Go figger.

    People do what they do and always have. You are the one making you angry by caring what they do or how they do it.

    I know that's not helpful, but it does give some perspective.

    I know. It's because I care too much about stuff. I only rant about things I care about.

    Sorry Andrew, you can have a good old rant about the lack of detail in this.

    Nitrogen doped porous carbon make supercapacitors with triple the energy capacity.
