Analysis of Complex Electrochemical Systems (ACES) lab

In our lab we study mechanisms within complex electrochemical systems. Practical electrochemical systems such as batteries, sensors, and fuel cells are often complex, involving engineered high surface area electrodes, starved electrolyte conditions, phase transformations, and interplay of the two electrodes. For these reasons there are significant deviations from ideal behavior as well as emergent or unexpected phenomena. We seek to understand these to engineer better devices for broad societal benefit, such as the worldwide adoption of sustainable energy.

I’m fortunate and honored to have received an NSF CAREER Award to use synchrotron techniques to continue studying the Mn-Bi interaction in rechargeable alkaline batteries. The full title of the project is “Engineering electrochemical reversibility in disordered materials for high energy density batteries.” Special thanks to Dr. Andrea Bruck and Matthew Kim, whose data were essential to the proposal. Northeastern did a nice magazine writeup about the project, which has a subheading called “Saving the World,” a level of drama/sincerity that I wholeheartedly endorse.
