Carbon nanotubes (CNTs) and graphene are being investigated for potential application as active electrode materials for electrochemical double layer capacitors (aka supercapacitors). Structural, and electronic characterization of these materials is being performed using various techniques. A range of solution-based electrode fabrication techniques are being explored as is solution preparation process. A Hitachi field- emission SEM is typically used for physical characterization. Electrical characterization is performed using a Princeton Advanced Research Versastat3-200 electrochemical workstation.  Other facilities include CNT/graphene growth furnaces, a fully equipped cleanroom, and significant materials characterization assets throughout the organization.
Research opportunities consist of investigations in the following areas: CNT/grapheme solution development, CNT/grapheme electrode fabrication, and electrolyte and packaging issues for making flexible/conformal supercapacitors. Internal research is in progress in these areas, in direct collaboration with universities and industry.
