3D-printed supercapacitor electrode breaks records in lab tests: Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets

Scientists have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous three-dimensional scaffold loaded with pseudocapacitive material. In laboratory tests, the novel electrodes achieved the highest areal capacitance (electric charge stored per unit of electrode surface area) ever reported for a supercapacitor.
