While I haven't looked into it much at all I have noted a great many "Roll your own SuperCap" videos on YouTube etc.
YouTube being YouTube; a lot of them are likely complete baloney, but most do carry on about getting a high surface area by using/applying Graphite or Graphene or even Activated Charcoal.
Activated Charcoal is just charcoal that has been heated red hot, which is how its made in the 1st place.
ie: Adding the word 'activated' just seems like a way to make people think they have to buy what is in fact plain old charcoal..?
Some seem to be flat packs that are sealed with a laminating machine, while others are rolled and stuffed into pill bottles and such.
The flat ones (if true) would make placing them next to a battery (packaging) convenient.
Might be worth researching more..?
