David Alan Wetz Jr., Ph.D. 
Associate Professor, Electrical Engineering, UTA
Director, Pulsed Power and Energy Laboratory 

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 David Wetz, UTA Pulsed Power and Energy Laboratorybatteries 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.

In this presentation, David 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 Wetz earned 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. Upon graduation, he became a Postdoctoral Fellow and, later, a research associate at the Institute for Advanced Technology at The University of Texas at Austin, where his work focused on advancing the development of electromagnetic launch systems. In 2008, he 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.
