Jung-Hyun Kim, assistant professor in the Department of Mechanical and Aerospace Engineering, received with partners Nexceris and Navitas a nearly $2.5-million grant from the Department of Energy to develop cathode materials for the next generation of electric vehicle batteries.
The project, “Cobalt-free LNMTO spinel cathode materials,” is one of 42 research projects sponsored through the Department of Energy program aiming to shore up U.S. energy security by supporting the development and commercialization of affordable, energy-efficient transportation technologies.
Increased energy efficiency plays no small part in the stability and growth of an economy driven by transportation. The average U.S. household spent about one-sixth of its total expenditures on transportation in 2017, according to a U.S. Bureau of Labor Statistics survey. That year, 11 billion tons of freight were transported by vehicles, with about $35 billion in products shipping each day, according to the Bureau of Transportation Statistics.
Demand for battery materials is also expected to increase as interest in electrical vehicles grows within the transportation industry.
Kim, who was recruited to The Ohio State University through the Institute for Materials Research-led Materials & Manufacturing for Sustainability Discovery Theme, will focus on developing materials to supplant prohibitively high-cost materials, such as Cobalt, used in electric-vehicle batteries. Cobalt is vital to the performance of lithium-ion (Li-ion) batteries, but recent increases in demand and price have resulted in shortages and concern about its outlook.
“Our work over the next three years will pave the way to a new generation cathode of Li-ion batteries,” Kim said. “Our goal is to develop low-cost cathode materials with high energy and power and demonstrate it using prototype battery cells with 2 Ah capacity, which can significantly impact Li-ion battery markets, mainly for electric vehicle (EV) applications.”
