University of California, Santa Cruz (UC Santa Cruz) and Lawrence Livermore National Laboratory researchers have developed new supercapacitor electrodes using a printable graphene aerogel to build a porous three-dimensional (3D) scaffold equipped with pseudocapacitive material.
In tests, the researchers say, the technology achieved the highest areal capacitance ever reported for a supercapacitor, potentially leading to wider use of fast-charging energy storage devices and novel designs for electronic products.
Said UC Santa Cruz's Yat Li, "The key innovation in this study is the use of 3D printing to fabricate a rationally designed structure providing a carbon scaffold to support the pseudocapacitive material. These findings validate a new approach to fabricating energy storage devices using 3D printing."
