Recent Progress on State and Parameter Estimation for Lithium-Sulfur Batteries

Abstract

This presentation will briefly explore some recent developments in the areas of lithium-sulfur (Li-S) battery modeling, parameter estimation, state estimation, and control. Widely recognized for their potential to provide attractive specific energy levels safely and inexpensively, Li-S batteries are governed by chains of multiple nonlinear redox and self-discharge reaction dynamics. This makes it important to develop novel battery management algorithms specifically tailored for the unique characteristics of Li-S batteries, particularly in contrast to their more traditional lithium-ion counterparts. The presentation will highlight some of the progress, as well as some of the key challenges and opportunities, in this emerging research domain.
