## Abstract

Intercalation materials, which allow ions to move in and out of a solid structure, are central to how lithium- and sodium-ion batteries store energy. Advancing this chemistry can lead to longer-lasting batteries and more reliable energy storage systems. However, current materials—mostly transition metal oxides and sulfides—can degrade over time as structural changes and reactions with the electrolyte reduce cycle life and performance. This research addresses these limitations by targeting dissolution issues that typically lead to capacity loss and instability during cycling. By developing new materials that are more stable and capable of storing more charge, this work aims to improve both battery lifespan and energy storage capacity. It also supports the use of sodium, a more abundant and cost-effective alternative to lithium, and relies on domestically available materials, helping reduce dependence on critical minerals like lithium. These advances could accelerate the development of sustainable, high-performance battery technologies for future energy systems. The project will provide outreach programs for grades 8–12 to inspire young students and help develop the future STEM workforce essential for ongoing innovation.

This project aims to develop novel transition metal sulfochlorides as a new class of intercalation materials for lithium- and sodium-ion batteries. This study hypothesizes that by controlling the formation of transition metal complexes upon dissolution, thes
