Solid-state batteries are becoming the next big thing in energy storage, with the promise of low volatility, high energy density and lower-cost manufacturing. With academia, industry and government collaborating on the next wave of development, we may see progress in this realm. Recently, the Department of Energy’s Oak Ridge National Laboratory and Solid Power Inc. of Louisville, Colo., signed an exclusive agreement licensing lithium-sulfur materials for next-generation batteries. A team of current and former ORNL researchers including Chengdu Liang, Nancy Dudney, Adam Rondinone, Jong Keum, Jane Howe, Wujun Fu, Ezhiylmurugan Rangasamy, Zhan Lin and Zengcai Liu developed the technology. This included designing and testing an all-solid lithium-sulfur battery “with approximately four times the energy density of conventional lithium-ion technologies.” It featured a …
