Researchers loaded 3D-printed structures of porous graphene aerogel with manganese oxide. This enabled them to capture an ultrahigh energy storage capacity into a small area. The energy densities are equivalent to that of some traditional batteries. Pseudocapacitors are a type of energy storage devices that could effectively balance the requirement of fast charging/discharging and high energy density. To realize practical pseudocapacitors, we need to develop a collector that can concurrently enable efficient electron transport and ion diffusion. The recent advances in 3D printing technology have offered new ways to address this exceptional challenge for pseudocapacitors. So far, numerous strategies have been employed to enhance the performance of these devices, including defect introduction, crystallinity engineering, and elemental doping. Recently, a team of researchers at the University of California, Santa Cruz and Lawrence Livermore National Laboratory built 3D-printed supercapacitor electrodes that are far superior to conventional supercapacitors in terms of energy […]
