RESEARCH INTERESTS

Material development for energy storage and conversion devices

Students will gain hands-on experience with a variety of analytical instrumentation and techniques related to energy storage and conversion including: UV-vis, fluorometer, potentiostat/electrochemistry, inert atmosphere glovebox operation, battery cell assembly and testing, and maintaining an electronic notebook.

 1.  Fluorescent carbon nanomaterials – Due to the unique nature of carbon it can adopt many different structural allotropes:  3-D (diamond, graphite), 2-D (graphene), 1-D (nanotube), or 0-D (fullerene).  Each of these allotropes have unique photophysical properties allowing them to interact with various wavelengths of light. This has led to their utilization in various applications from biological imaging to fluorescent polymers.  The research from this lab will develop novel carbon based nanocomposite materials that can be utilized as multimodal imaging agents in biological systems and for energy down conversion devices such as LEDs.

 2.   Solid state electrolytes Current lithium ion batteries are a ubiquitous part of our daily lives, however, there is an inherent safety risk associated with their use.  This is due to the poor stability of the flammable organic electrolyte solution utilized to shuttle the lithium ions between the anode and the cathode during charging and discharging.  The goal of this project is to replace the liquid electrolyte with a solid one that eliminates the fire risk.  Additionally, the use of solid electrolytes will also allow for the use of high capacity and higher voltage anodes and cathodes that can increase the energy density of the battery.

 3.  High capacity nano-carbon composite anodes– In commercially available lithium ion batteries, the anode material is typically graphite.  While graphite has an acceptable capacity and good cycle stability, a much more stable and higher capacity anode material is needed for the next generation of lithium ion batteries to meet mobile and transportation requirements.  This has led to the development of various high surface area carbon composite materials that have a much higher stability and capacity than graphite.  Additionally, these materials can also reversibly store other alkali (Na+, K+) and alkaline earth (Ca2+, Mg2+) metals.  These metals are an less expensive and more abundant than lithium.  This project will focus on the understanding the fundamental interaction(s) of these metals with the carbon nanostructure which will aid development of nano-carbon composite anodes that can reversibly interact with these metal ions for new battery chemistries.
