Development of Structural Batteries with Improved Multifunctional Efficiency for Aerospace Applicati
Abstract
The purpose of this action is to add a FY22 funding increment in the amount of $170,000.00 for a new Grant with the University of Te,xas @ Dallas.--Structural batteries based on multifunctional materials and structures to integrate structural and electrochemical en,ergy storage functions 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 in,to aircraft and weapons. The conventional trade-off of mechanical strength and energy density of structural battery devices still ca,nnot be broken, and hence the multifunctional efficiency cannot meet the demand from the Navy. Moreover, the electrodes are prone to, delaminate from the structure after cycles due to the insertion and extraction of ions, which results in capacity loss and the detr,iment of the mechanical strength of the structural battery. Herein, in this project, the overarching research objective is to develo,p novel structural batteries to overcome the conventional trade-off and improve the multifunctional efficiency over 1.5. This can be, achieved by systematically understanding the effect of the structure of the multifunctional parts in structural battery on the elec,trochemical and mechanical properties, strategies for their control, and mechano-electrochemical correlation. A novel nanostitch str,ucture will beintroduced between the electrodes, which not only reinforces the mechanical strength of the structural cell but also p,rovide aligned channels to enhance lithium (Li) ion transport. The proposed project is highly aligned with the mission of the progra,m Aerospace Structures and Materials of ONR to develop multifunctional materials and structures to meet the demands of the current a,nd future needs of Navy and Marine Corp air vehicles and weapons. This project is also highly related to the vision of the Naval Res,earch and Development Framework for operational endurance with the improvement of energy storage and efficiency for propulsion and w,eapons systems.
