Development of Structural Batteries with Improved Multifunctional Efficiency for Aerospace Applicati
Abstract
Structural batteries based on multifunctional materials and structures to integrate structural and electrochemical energy storage fu,nctions simultaneously are promising to reduce parasitic weight in air vehicles and weapons, making them more lethal. However, state,-of-the-art technologies on the structural battery still have issues that hamper its further practical integration into aircraft and, weapons. The conventional trade-off of mechanical strength and energy density of structural battery devices still cannot be broken,, and hence the multifunctional efficiency cannot meet the demand from the Navy. Moreover, the electrodes are prone to delaminate fro,m the structure after cycles due to the insertion and extraction of ions, which results in capacity loss and the detriment of the me,chanical strength of the structural battery. Herein, in this project, the overarching research objective is to develop novel structu,ral batteries to overcome the conventional trade-off and improve the multifunctional efficiency over 1.5. This can be achieved by sy,stematically understanding the effect of the structure of the multifunctional parts in structural battery on the electrochemical and, mechanical properties, strategies for their control, and mechano-electrochemical correlation. A novel nanostitch structure will be,introduced between the electrodes, which not only reinforces the mechanical strength of the structural cell but also provide aligned, channels to enhance lithium (Li) ion transport. The proposed project is highly aligned with the mission of the program Aerospace St,ructures and Materials of ONR to develop multifunctional materials and structures to meet the demands of the current and future need,s of Navy and Marine Corp air vehicles and weapons. This project is also highly related to the vision of the Naval Research and Deve,lopment Framework for operational endurance with the improvement of energy storage and efficiency for propulsion and weapons systems,.
