Dissertation Title: HYBRID CORE-SHELL NANOWIRE ELECTRODES UTILIZING VERTICALLY ALIGNED CARBON NANOFIBER ARRAYS FOR HIGH-PERFORMANCE ENERGY STORAGE.
(hdl.handle.net/2097/27651)
Research Focus: Hybrid heterostructured electrodes for use in lithium ion batteries and capacitors. Vertically Aligned Carbon Nano Fibers (VACNF) provide an excellent scaffold to support lithium active materials, such as Silicon, Tin, Titanium Oxide, Manganese Oxide, and Lithium Cobalt Oxide. This 'Hybrid' composite electrode was able to achieve near theoretical capacity of the functional material by utilizing the three-dimensional structure of VACNFs to providing greater active surface area, improved diffusion kinetics, and greater conductivity to active material.
Other projects involved the study of psuedo, electrochemical, and electrostaic capacitance involving various carbon, metal oxide components.
