Lithium and Sodium Metal Solid State Batteries for Advanced Energy Storage

The proposed innovation consists of solid-state batteries that use either lithium or sodium metal as the anode material; these batteries offer a breakthrough in terms of energy per unit mass and volume at the cell level (>30% improvement vs. current Li-ion batteries), cost (by increasing energy density and using low-cost materials), safety (by use of electrolyte materials with improved intrinsic thermal stability), and an ability to serve numerous end-use sectors including specialized applications such as aerospace, as well as larger markets in transportation and stationary storage. The cooperative project will focus on advancing the science and development of solid state batteries, including work on advanced coatings, cell components, cells, and materials informatics software, for both Na and Li metal batteries.
