August 5, 2025 | “The beauty of our approach is that it’s simple, dry, low-cost and environmentally friendly,” said Dr. Ma, “and the performance improvements are dramatic.”

A new study led by Lin Ma, Ph.D., an assistant professor in the Department of Applied Physical Sciences at University of North Carolina at Chapel Hill, offers a creative and environmentally friendly solution. Published in Chemistry of Materials, the research describes how Dr. Ma’s team, which included lead author Vadim Shipitsyn, developed a technique to improve one of the most important parts of a sodium-ion battery: the cathode—the part that stores and releases energy during each charge and discharge cycle. 

“This is an exciting step forward in making sodium-ion batteries more practical,” said Dr. Ma. “By simplifying the way we modify the cathode, we’re opening the door to greener, cheaper and more scalable energy solutions.”
