Abstract
A three-dimensional nanocomposite of pompon-like MnO2/graphene hydrogel was prepared. The 3D graphene hydrogel not only provides a good support to stabilize MnO2 but also facilitate the fast ion mobility and electron transfer. The composite exhibited a good capacitive performance (445.7Â FÂ gâ1 at 0.5Â AÂ gâ1) and stability (82.4% retention after 5000 cycles).
