Funding will support the project team's small-scale research and development of smart multifunctional structural batteries (SMSB) for use in electrified aircraft (E-Aircraft) by integrating energy storage directly into load-bearing aircraft structural components using 4D printing. Specifically, the project team will (1) fabricate, test, and validate SMSB components to meet performance metrics, (2) combine components, test and validate integrated SMSB system to meet performance and safety metrics, and (3) conduct a techno-economic analysis and life cycle assessment for next phase development. If successful, this project will result in a lighter, longer lasting, and energy efficient SMSB technology for E-Aircraft, ultimately improving energy efficiency and reducing dependence on foreign energy sources, thereby increasing U.S. energy security.
