Plating Insulating Material Onto Metal or Carbon

Hello All!
I recently saw an interesting method of making low volume, high surface area electrodes (in this case, for supercapacitors) at It involves Carbonizing a sponge and then plating it with an electrically insulating material. I was wondering if anyone knows of any insulating materials that go into ionic solution (so they can be plated) and hopefully don't require baking after the plating to make them insulators. What I would like to do is carbonize a sponge or similar "electrode", plate it with electrical insulation and use an electrolyte solution as the other "electrode", as suggested by the above mentioned website. Any help or leads would be greatly appreciated...Thanks!

You might try using the carbon as an anode in an acidic solution that contains Mn +2 ions.

The manganese should coat the anode with an insulating coating of MnO2, manganese dioxide.
