Drexel's Gogotsi and team advance understanding of energy storage mechanisms in Nature Materials
Date:3/5/2012

An international team of materials researchers including Drexel University's Dr. Yury Gogotsi has given the engineering world a better look at the inner functions of the electrodes of supercapacitors the low-cost, lightweight energy storage devices used in many electronics, transportation and many other applications. In a piece published in the March 4 edition of Nature Materials, Gogotsi, and his collaborators from universities in France and England, take another step toward finding a solution to the world's demand for sustainable energy sources.

Gogotsi, a professor in Drexel's College of Engineering and director of the A.J. Drexel Nanotechnology Institute, teamed with Mathieu Salanne, Cline Merlet and Benjamin Rotenberg from the Universit Paris 06, Paul A. Madden from Oxford University and Patrice Simon and Pierre-Louis Taberna of Universit Paul Sabatier. What the group has produced is the first quantitative picture of the structure of ionic liquid absorbed inside disordered microporous carbon electrodes in supercapacitors. Supercapacitors have the capability of storing and delivering more power than batteries; moreover, they can last for up to a million of charge-discharge cycles. These characteristics are significant because of the intermittent nature of renewable energy production.

According to the researchers, the excellent performance of supercapacitors is due to ion adsorption in porous carbon electrodes. The molecular mechanism of ion behavior in pores smaller than one nanometer-one billionth of a meter- remains poorly understood. The mechanism proposed in this research opens the door for the design of materials with improved energy storage capabilities.

The authors suggest that in order to build higher-performance materials, researchers should know whether the increase in energy storage is due to only a large surface area or if the pore size and geometry also play a role. The results of this study provide guidance for development of better electrical energy storage devices that will ultimately enable wide utilization of renewable energy sources.

"This breakthrough in understanding of energy storage mechanisms became possible due to collaboration between research groups from four universities in three countries," Gogotsi said. "Moreover, the team used carbon structure models developed by our colleagues Dr. Jeremy Palmer and Dr. Keith Gubbins from the North Carolina State University. This is a clear demonstration of the importance of collaboration between scientists working in different disciplines and even in different countries."
