The explosion in the popularity of electric vehicles (EV) in recent years has been tempered by the nagging challenges of the batteries that power them. Current models are heavy, adding significant weight to the vehicles, and don’t allow for driving very far on a single charge.
A faculty member at North Carolina Agricultural and Technical State University is tackling those challenges, however, with work that is drawing interest and earning support from the auto manufacturing industry. Sung-Jin Cho, Ph.D., an assistant professor in the North Carolina A&T Department of Nanoengineering, is developing a new generation of solid-state lithium batteries that will enable EVs to basically do more with less.
Cho’s work focuses on two specific areas: high-performance, hetero-structured cathode material and the fundamental study of rotating molecules for polymer electrolytes.
Cho and his team pursue their work in a state-of-the-art battery laboratory at the Joint School of Nanoscience, an academic collaboration between North Carolina A&T and the University of North Carolina at Greensboro. Cho’s testing environment rivals what automakers have at their own facilities, which potentially shortens the path from laboratory to marketplace.
