Scientists at Rice University designed a boric acid-infused graphene microsupercapacitor with quadrupled ability to store an electrical charge, while greatly boosting its energy density. This design may see potential applications in wearable electronics, as well as many other flexible electronics uses.
The scientists used commercial lasers to create thin, flexible supercapacitors by burning patterns into common polymers. The laser burns away everything except for the carbon, to a depth of 20 microns on the top layer, which becomes a foam-like matrix of interconnected graphene flakes. They found that first infusing the polymer with boric acid, resulted in major performance advantages.
