## Abstract

Lithium-ion batteries are the backbone of modern electric vehicles (EVs) and play a critical role in reducing greenhouse gas emissions and promoting energy-efficient transportation. Vibration is an inherent and inevitable operating condition for on-board EV batteries. The effects of vibration on battery performance are poorly understood because vibration can affect several battery internal degradation mechanisms. These degradation processes directly reduce vehicle travel range and overall battery life. This project will use experiments and modeling to uncover the intricate mechanisms of battery degradation triggered by vibration, including structural and stress evolution, which often take place simultaneously with chemical degradation and accelerated battery capacity loss. The results of the project will inform the design of safer, more durable, and higher performance batteries. The interdisciplinary nature of this research, combining electrochemistry, materials science, and mechanical engineering, could inspire new collaborative research efforts and educational initiatives, fostering the development of a skilled workforce in the critical field of energy storage technology.

This project will investigate vibration-induced degradation in Lithium-ion battery cells using a comprehensive approach that integrates systematic experimental studies with electrochemical modeling. The project will characterize both short-term and long-term degradation processes by examining the interp
