Electrochemical Capacitors (ECs), sometimes called supercapacitors or ultracapacitors, are receiving increased attention for use in power sources of many applications because they offer extraordinarily high reversibility, provide unexcelled power density, and have exceptional cycle-life. Combination systems, including those with batteries and capacitors, IC engines and capacitors, and fuel cells with capacitors are now appearing and being used to increase the energy efficiency of vehicles and industrial equipment like fork lifts, trams, and overhead cranes by capturing energy that is normally wasted. Systems developed specifically for grid power quality applications are now appearing.
This tutorial is targeted at technologists interested in understanding and exploiting electrochemical capacitor technology. The basics are covered first, including a description of the nature and significance of electric double layer charge storage, the general design of such products, and the similarities and differences between these devices and traditional capacitors and batteries. Two-terminal electrical measurement techniques are discussed and test data is used to develop equivalent circuit models. Power/energy behavior and tradeoffs are presented along with reliability design. Many example applications are covered in detail. The goal of the tutorial is to provide basic understanding, necessary tools, and sufficient operating information to allow direct and successful advancement and/or exploitation of electrochemical capacitor technology.
About the Instructor
John R. Miller President of JME, has more than 25 years of experience in research, development, commercialization, evaluation, testing, and modeling of capacitor technologies, products, and systems. Since founding JME in 1989, he has assisted in the development and market introduction of several electrochemical capacitor products now available for commercial, military, and medical applications. Dr. Miller was a pioneer in the development of third-generation electrochemical capacitor technology, and he advanced the development of several asymmetric capacitor systems. He has assisted material suppliers in creating products having enhanced performance capabilities for capacitors and assisted DOE in establishing appropriate test methods and evaluation procedures for large, high-power capacitors.
Dr. Miller has published more than 50 capacitor-related papers, prepared many government reports, and been awarded 10 U.S. patents. He has organized and chaired international conferences on electrochemical capacitor technology and teaches short courses for several professional societies. Periodically Dr. Miller is invited to brief several government organizations on this capacitor technology. In addition to his position with JME, Inc., Dr. Miller is a part time Research Professor at the Great Lakes Energy Institute of Case Western Reserve University. His previous positions include research manager at SOHIO, staff scientist at the Laboratory for Laser Energetics at the University of Rochester, and staff member at Los Alamos National Laboratory. John R. Miller holds BS and PhD degrees in physics from MIT.
