The UA Department of Energy’s Office of Energy Efficiency and Renewable Energy (DOE EERE) has awarded a $5-million, three-year grant to a project led by Penn State to develop a lithium-sulfur (Li-S) battery with a volumetric energy capacity of 600 Wh/liter.
Penn State and its project colleagues had earlier been encouraged by the DOE’s ARPA-E to submit a full application on their proposed Li-S batteries to one of the ARPA-E advanced research funding opportunity announcements, but were not selected for funding.
Penn State will work with EC Power, Johnson Controls, and Argonne National Laboratory on the EERE-funded project; Donghai Wang, assistant professor of mechanical engineering, Penn State, will lead the project.
The research team plans to include a nanocomposite sulfur cathode and lithium-rich composite anode material. They will also develop a nonflammable electrolyte for these batteries that will extend cell cycling life and safety. Johnson Controls and EC Power will create a cell technology to streamline manufacturing of safe, reliable and economical long lasting advanced cells.
The award is part of the DOE’s Advanced Vehicle Research and Development program, which aims to improving fuel efficiency of next generation vehicles.
