Batteries degrade over time, which is why older phones lose power faster. An international team led by Professor Mike Toney has uncovered the cause of this degradation, paving the way for improved batteries that could extend the range of electric vehicles and advance clean energy storage.

Researchers in the Department of Chemical and Biological Engineering and Materials Science and Engineering Program have published new findings in Joule that could lead to the development of better hybrid lead halide perovskites – a class of materials proposed for use as low-cost, high-efficiency solar cells.

The DOE has awarded $400 million for research into clean energy technologies and low-carbon manufacturing through 43 Energy Frontier Research Centers, six of which feature 13 Renewable and Sustainable Energy Institute (RASEI) members, including ChBE professors Seth Marder, Mike Toney and Wilson Smith. RASEI is a joint institute between CU Boulder and the National Renewable Energy Laboratory.
