Energy Storage Seminar

“Why would Telsa Motors partner with some Canadian?”

Jeff Dahn, Dalhousie University, Halifax, Canada

11 a.m. on Wednesday, April 20th, Robotics Manufacturing Building (RMB) Room 323 

Abstract: Lithium-ion batteries are amazing.  They power our phones, tools and now vehicles.  Unfortunately they eventually die.  Creating a Li-ion cell that lasts a long time (decades) is very difficult but proving that it will is much more difficult.  I will discuss the reasons why Li-ion batteries die and how advanced diagnostics can be used to select new electrolyte formulations that improve the lifetime of Li-ion cells to the decades-long scale.  Tesla will enter into a 5 year research partnership with us in June 2016.  

Prof. Dahn is recognized as one of the pioneering developers of lithium-ion batteries.  His recent research concentrates on the application of combinatorial materials science methods to battery and fuel cell problems.

The Design, Synthesis, and Characterization of Electron-Donating Phenothiazines for Electrochemical Energy Storage Applications

"Electron-Donating Phenothiazines for Energy Storage Applications"

Prof. Susan A. Odom

Department of Chemistry, University of Kentucky

Phenothiazine derivatives have seen widespread use as stable electron-donating organic compounds with generally stable oxidized states, which makes them an attractive core for functionalization for use in electrochemical energy storage applications. With phenothiazine itself as a starting material, functionalization of the 3, 7, and 10 positions is facile, providing options to modify redox potentials and improve stability in both the neutral and singly oxidized (radical cation) states. Additionally, this ring system can be built from aryl amines and aryl bromides, allowing for the production of compounds with even more functionalization, including incorporating groups at the 1 and 9 positions and – in some cases – at every sp2-hybridized C atom in the aromatic core. In many cases, computational studies have predicted what we have observed experimentally, and often guides our design of next-generation materials. This presentation focuses on the characterization of phenothiazine derivatives, both from experimental and computational approaches, and includes results from their incorporation into lithium-ion batteries as electrolyte additives for overcharge protection as well as studies toward using them in non-aqueous redox flow batteries as catholytes. 

This seminar is part of the 2015-16 Energy Storage Seminar Series at UK supported by NSF EPSCoR under Award No. 1355438.

Second Video in Kentucky EPSCoR Series Features VOEIS Project

In 2009, the Virtual Observatory And Ecological Informatics System (VOEIS) project was launched. Funded by an NSF EPSCoR grant, VOEIS united researchers at five universities in Kentucky and two universities in Montana to research the consequences of environmental changes in freshwater ecosystems.

Kentucky NSF EPSCoR Success Stories Featured in Video Series

Schyler Nunziata is a first-year Ph.D. student in biology at the University of Kentucky, and she’s the first success story highlighted in a new video series.

Kentucky NSF EPSCoR success stories: Schyler Nunziata

 

 

Schyler Nunziata is a first-year Ph.D. student in biology at the University of Kentucky, and she's just one of the young scientists that can testify to the impact of Kentucky's Experimental Program to Stimulate Competitive Research, known as Kentucky EPSCoR. Nunziata, who works in David Weisrock's lab that combines genetics, genomics and evolutionary biology, received two grants from the National Science Foundation through EPSCoR. The first $5,000 grant, while she was a masters student at Eastern Kentucky University, funded her entire thesis project which involved collecting two lined salamanders, developing genetic markers, and genotyping the salamanders. The second grant, as a Ph.D. student at the University of Kentucky, allowed her to prepare a pilot study. Nunziata says, "EPSCoR helps get students into research, helps develop them as scientists. For me, it allowed me to delve deeper into a field that I was interested in and find out what research was like and what a career in research would entail. EPSCoR has had a huge impact on my career path."

Kentucky EPSCoR has been the channel for over $430 million in research funding to the Commonwealth's academic institutions. Over 80 percent of this funding has been competitively won from federal research programs. In addition to supporting 1,400 research jobs and providing research training for over 2,300 students, this funding has created 21 research centers and major research initiatives on Kentucky's campuses.
