Porous MnO2 for use in a high performance supercapacitor: replication of a 3D graphene network as a reactive template.
نویسندگان
چکیده
Graphene oxide hydrogel is used as a reactive template to prepare nanoporous materials with a 3D microstructure. The as-prepared porous MnO2 shows a capacitance retention of ~70.6% at a current density as high as 15 A g(-1), resulting from the 3D interconnected ion transport channel replicated from the graphene oxide hydrogel.

متن کاملEnhancing the supercapacitor performance of graphene/MnO2 nanostructured electrodes by conductive wrapping.
MnO2 is considered one of the most promising pseudocapactive materials for high-performance supercapacitors given its high theoretical specific capacitance, low-cost, environmental benignity, and natural abundance. However, MnO2 electrodes often suffer from poor electronic and ionic conductivities, resulting in their limited performance in power density and cycling. Here we developed a "conduct...
