Visualizing a battery's lithium "whiskers" and their degrading effects

A recent study pinpointed the reaction front where lithium (Li) dendrites can come into contact with cathode materials. It also detailed the Li propagation pathway and reaction steps that lead to cathode failure.

CME researchers from University of Wisconsin-Madison report new fuel cell concept

Researchers from the Center for Molecular Electrocatalysis (CME) – Shannon Stahl and Thatcher Root – published a paper October 3 in the new energy journal Joule titled “Quinone-Mediated Electrochemical O2 Reduction Accessing High Power Density with an Off-Electrode Co-N/C Catalyst.”

CME researcher Brandi Cossairt honored with National Fresenius Award

Center for Molecular Electrocatalysis (CME) researcher Brandi Cossairt is the 2018 recipient of the National Fresenius Award. This award is administered by the American Chemical Society and sponsored by Phi Lambda Upsilon, the National Chemistry Honor Society.

For hydrogen power, two metals may be better than one

A clever catalyst design from PCSD chemists Geoffrey Chambers, Eric Wiedner, and Morris Bullock employs iron and chromium to carry out the reactions that convert hydrogen to electricity. The solution, recently published in Angewandte Chemie International Edition, allows two abundant metals to share a role that typically falls to a single, costly metal: platinum.

Tuning the electrocatalytic performance of bifunctional catalysts

Scientists are working together to study perovskite-structured rare-earth nickelates (RNiO3) that can serve as bifunctional catalysts capable of performing both the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER).
