This project is jointly funded by the CBET Electrochemical Systems Program and the Established Program to Stimulate Competitive Research (EPSCoR). The goal of the project is to develop a new rechargeable battery based on an Aluminium (Al)-CO2 electrochemical cell. The project will address several challenges generally associated with metal-CO2 batteries, including the reversible formation and decomposition of solid discharge products. It will focus on the use of additives in the electrolyte to mitigate these challenges. The new battery will serve two important purposes by storing electrical energy and simultaneously capturing gaseous CO2 and converting it into solid minerals. The project will support an educational program about metal-CO2 batteries for students at all academic levels. The project will expand educational outreach at the University of New Mexico by providing hands-on energy and sustainability demonstrations for rural elementary K-12 schools. The goal is to stimulate interest in STEM and help develop a future science and engineering workforce. Leveraging a comprehensive, multidisciplinary approach that includes material science, electrochemistry, engineering, and systems integration, this project is designed to address critical scientific challenges in the development of metal-gas battery technology. The research focuses on understanding the reversible formation and decomposition of solid discharge products within Al-CO2 batteries. Objectives include de
