The objective of this project is to develop a reliable and fast predictive tool for battery cycle life through a full understanding and characterization of the nature of primary deterioration and failure processes in Valve-Regulated Lead Acid (VRLA), Nickel Metal Hydride (Ni-MH) and Lithium-Ion (Li-Ion) batteries, respectively. The project will use the integrated experimentation and computational fluid dynamics (CFD) approach to develop a mathematical model describing these deterioration and failure processes as they affect the life and long-term performance of the batteries. The project is a collaborative effort with Dr. B.Y. Liaw at the Hawaii Natural Energy Institute of University of Hawaii.
