The Department of Chemical and Biological Engineering presents its spring 2025 seminar series featuring Chibueze Amanchukwu, Neubauer Family Assistant Professor and Pritzker School of Molecular Engineering at University of Chicago, who will present “Innovating in—and Learning from—Battery Science to Address Challenges in Electrochemistry.” This seminar will take place on Wednesday, April 2, from 3:15–4:30 p.m. in room 131 (auditorium) of Perlstein Hall.

Abstract

Electrochemical energy storage and conversion technologies are of great importance because they can enable the deployment of renewable energy in numerous applications (transportation, manufacturing, electricity generation, environmental remediation and more). Unfortunately, many of the challenges that prevent the deployment of next generation batteries or earth abundant electrocatalytic systems can be traced to a lack of suitable electrolytes. Electrolytes are the ionically conductive media that is in contact with both electrodes. In this talk, I will discuss (1) my groups’ focus on the design of novel electrolytes for next generation batteries. We deploy data science approaches to navigate wide electrolyte chemical spaces and accelerate electrolyte selection. Furthermore, we develop solvent-free inorganic molten salt electrolytes that eliminate many of the safety hazards that face conventional electrolytes. (2) We use ideas from battery electrolyte design to address challenges in electrocatalysis and environmental remediation. We show that by modulating water activity and subsequent reactivity in ‘designer’ electrolytes, undesired hydrogen evolution reaction can be suppressed to enable waste valorization such as CO2 conversion to fuels and chemicals. Finally, our focus on developing novel electrolytes and exploring them in electrochemical devices enables the development of earth-abundant batteries and electrocatalytic systems with earth-abundant catalysts.

Biography

Chibueze Amanchukwu is a Neubauer Family Assistant Professor in the Pritzker School of Molecular Engineering at University of Chicago, a faculty affiliate in the Data Science Institute, and a joint appointee at Argonne National Laboratory. His research is focused on enabling long duration electrical (batteries) and chemical energy storage for a sustainable energy future. His team is especially interested in modifying electrolyte and ion solvation behavior to control electrochemical processes occurring in batteries and the valorization of waste (e.g., CO2) to valuable fuels and chemicals. He has been named a “Talented Twelve” by Chemical & Engineering News (C&EN) and an Inventor Under 35 by MIT Technology Review (Global). His work has been recognized with the NSF CAREER Award, DOE Early Career Award, Army Research Office Early Career Award, Google Research Scholar Award, Camille-Dreyfus Teacher-Scholar Award, ECS-Toyota Young Investigator Fellowship, CIFAR Azrieli Global Scholar Award, and the 3M Nontenured Faculty Award. He obtained his Ph.D. in chemical engineering as a NDSEG Fellow at MIT and was a TomKat Center Postdoctoral Fellow at Stanford University.
