Science Highlights

Oak Ridge National Laboratory researchers have uncovered a path to design superionic polymer electrolytes for solid-state batteries and other energy applications that could help ensure a future of abundant and reliable energy for the United States. The scientists demonstrated that by carefully controlling the chemical composition of a lithium salt-based polymer, they could create a material that enables superfast transport of ions in batteries and many other energy storage and conversion technologies.

Researchers at the Department of Energy’s Oak Ridge National Laboratory developed a method to convert a commonly discarded hydrocarbon polymer into gasoline- and diesel-like fuels. The team has applied for a patent for the discovery, which treats polyethylene — the stuff of white cutting boards and shopping bags — with aluminum chloride-containing molten salts that serve as both solvent and catalyst. The results were published in the Journal of the American Chemical Society.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have advanced the knowledge required to improve large-scale energy storage. In doing so, they have revealed distinct chemical reactions that improve the stability and efficiency of a promising energy-storage system. Their findings suggest positive implications for U.S. energy security, including increased national power grid reliability and affordability.
