Evaluation of Lithium-ion Batteries in UTA's Pulsed Power & Energy Lab
David A. Wetz Jr., Ph.D.
Associate Professor, Electrical Engineering
Director, Pulsed Power and Energy Laboratory
University of Texas at Arlington
Every day the world is becoming more reliant on energy storage. The needs are vast and the uses vary from powering small consumer electronics to very large electrical grid backup power systems. Lithium-ion batteries offer high power and energy density, making them an attractive storage solution However, little research has been done to study how electrochemical cells age and degrade at the materials level when they are operated under high electrical and thermal stress. Over the past several years, researchers in the Pulsed Power and Energy Lab at UT Arlington have conducted investigations into how lithium-ion batteries perform and age in those situations. Some of the methods used are novel in nature and aimed at in-situ analysis, while others are more traditional and used in the post-mortem state.
In this presentation, Dr. Wetz provides an introduction to lithium-ion batteries, an overview of some of the work performed in the P.P.&E. lab and some outcomes discovered to date.
David A. Wetz, Jr. received B.S. degrees in electrical engineering and computer science from Texas Tech University in 2003 and M.S. and Ph.D. degrees in electrical engineering from Texas Tech in 2004 and 2006, respectively. He was an undergraduate and graduate research assistant in the Center for Pulsed Power and Power Electronics, where his research was focused in the areas of pulsed power system design, pulsed dielectric breakdown of liquids, and ion thruster optimization. Upon graduation, Dr. Wetz became a Postdoctoral Fellow and, later, a research associate at the Institute for Advanced Technology at the University of Texas at Austin. There, his work was focused on advancing the development of electromagnetic launch systems. In 2008, Dr. Wetz was recognized as an Outstanding Young Researcher at the 2nd Euro Asian Pulsed Power Conference in Vilnius, Lithuania. Since joining UTA in 2010, his research has focused in the areas of pulsed power, MicroGrid design and optimization, and understanding the limitations of using electrochemical energy storage devices in pulsed power systems.
