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 electric vehicles to 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.
Cho’s focus on nano-architected energy storage encompasses a wide variety of applications. In addition to its potential use for the electric vehicle industry, an apparel manufacturer has tasked Cho’s team with pioneering advanced flexible, wearable, high-energy lithium batteries that can be integrated into garments.
Cho’s research also supports BioSolar, Inc., which is developing a breakthrough technology to double the storage capacity, lower the cost and extend the life of lithium-ion batteries. The company funds Cho’s research, and currently licenses one of his inventions for nano material based super-cathode technology.
Cho, who holds a Ph.D. in Material Engineering from Marquette University, is involved in research for the Air Force and other government agencies, as well.
