Graphene is a one atom thick two-dimensional material that exhibits exceptional physical and electronic properties, and offers alternative and cost-effective applications in energy storage, biosensors, and medicine. This talk will describe innovative approaches for the synthesis of hierarchical three dimensional graphene hybrid materials which possess characteristics including ultra large surface area, mechanical durability and high conductivity which are appealing to diverse energy storage systems. Rapid charging and discharging supercapacitors are promising alternative energy storage systems for applications such as portable electronics and electric vehicles. Integration of pseudocapacitive metal oxides with structured nanomaterials has received a lot of attention recently due to their superior electrochemical performance. In order to realize high energy density supercapacitors, we developed a simple and scalable method to fabricate graphene-MWNT-metal oxide nanowire hybrid systems. Excellent capacitance retention and high charge-discharge cycles have been demonstrated. Such multi-scale engineered materials could have wide range implications to facilitate new technological innovations in energy storage.
