## Abstract

Metal-ion batteries are widely used in electric vehicles, portable electronics, and energy storage for the power grid. Lithium-ion batteries have enabled many of these advances, but they are reaching limits in energy density and cost. Calcium-ion solid-state batteries are a promising alternative because calcium is abundant, low-cost, and capable of storing large amounts of energy. However, progress has been limited by the lack of solid electrolytes that can efficiently transport calcium ions at room temperature and remain stable when in contact with battery electrodes. This project aims to speed up the discovery of high-performance calcium solid electrolytes and to improve understanding of how calcium ions move through these materials. It will use data-driven approaches and advanced computer simulations. Large materials databases will be screened to find promising candidates. First-principles simulations will be used to study ion transport at the atomic scale. The project will also support education and outreach by involving students in research and promoting STEM learning in local schools. These efforts will help prepare a skilled workforce. Overall, this project will help develop safer, lower-cost, and high-performance energy storage systems, thereby strengthening energy security in the United States.

This project will focus on identifying, characterizing, and optimizing inorganic calcium-ion conductors that can approach superionic conductivity at room temperature. A key
