Development of NiOOH Nanosheet/Graphene Hydrogels for Asymmetric Supercapacitors

摘要

NiOOH nanosheet/graphene hydrogels(HNiOOH/GS),with mesoporous NiOOHnanosheets uniformly dispersed within the highly in-terconnected 3D graphene network,are construct-ed and studied for the first time by a mixed solvo-thermal and hydrothermal reaction.The effect of sol-vent composition on the morphology,phase,anddispersibility of nanocrystal and hydrogel strength
