Battery Tech: From Flashlights to Teslas and Beyond

Associate Professor of Energy, Environmental & Chemical Engineering
Co-founder and Interim Director, Solar Energy and Energy Storage (SEES) Initiative

Moderated by: Cynthia Wichelman, M.D.


Venkat Subramanian, Ph.D.

Have you ever tried shaking a flashlight when it didn't work, and then it worked, but only for a short time? Batteries—in particular lithium-ion—are human-like devices. They like to operate at 65-75°F, operate well when they eat well (store less), but can only deliver less than what they have consumed. Their performance degrades with age and they don't work well when they have been inert for a long time. This talk will introduce the materials, chemistry, modeling and control challenges and opportunities for improving the performance of batteries for vehicles, satellites and the renewable electric grid. In particular, current research on operating these devices at their optimal point (Body Mass Index) will be presented.

Science On Tap highlighted on St. Louis Public Radio and Voice of America!

Science On Tap is a place where, for the price of a beverage, anyone can come to explore the latest ideas in science and technology. Meetings take place outside a traditional academic context, in the Crown Room at Schlafly Bottleworks.


Meetings are held on the last Wednesday of the month during the academic year, usually from 7:00 - 8:30 PM. The standard format is as follows: about 45 minutes of presentation, followed by discussion until 8:30 PM. Seating is limited to the first 100 people.  No reservations accepted.
