Nanocarbon paper battery - supercapacitor

Have a look at this new nanoparticel carbon in cellulose paper cell:

Very interesting !

It is a very interesing idea to put conductive carbon or graphite into
its own cellulose paper and thus build bigger conductive graphite paper plates this way.

Now what was new to me is, that there exists ionic liquids,
that have just ions in them.

That is the perfect fuel for these paper electrodes, as a supercapacitor
is just working this way, that it has a soaked up ions in its electrode mesh.

Thus the ions charge up the electrode plates and when one electrode
plate has positive ions in them and the other electrode plate has
negative ions in them you can connect a load between the electrodes and
a current will flow...

Now, how do we get cheap ionic liquids ?

How can we just charge up water and sperate it, so that one
can get one bottle full of OH- ions and one bottle
of H3O+ ions ?

Any idea ?

Put one graphite paper plate in OH-
and another one in H3O+ and
voila you have a very nice refillable battery/supercapacitor
which can be refilled just by the ionic liquids !

Does anyone find their paper:

"Flexible Energy Storage Devices Based on Nanocomposite Paper"

anywhere on the net and can post it here ?
Many thanks.

Hi Stephan,

Just have one container of Acid (H₃O⁺ <--> H⁺ + H₂O) Say hydrochloric or sulfuric acid, that will give you your hydronium ions.

and the other container of Base ( H₂O <--> H⁺ + OH^-) say sodium or potassium hydroxide, that will give you your hydroxide ions.

Wait a minute, lol, does this sound like a battery? Very interesting. It will probably work just like a battery too.

Advantages? Not sure.

Hi ResinRat,
no, we need a ionic liquid
where we don?t have charge equilibrium !

So how can we extract from water just the OH- ions for example ?
or have more OH- ions in water than H+ ( or H3O+) ions ?

Can this be done by charging up water somehow in 2 containers ?
One which will be more positive and one will be more negative ?
