Development of a New Lithium-Sulfur Battery Model to Accurately Represent Dendrite Growth and the Shuttle Effect

Abstract

This paper presents a Simulink model of a Lithium-Sulfur battery that highlights the dendrite growth and shuttle effect, two major challenges found in Lithium-Sulfur batteries. The model shows how these will increase internal resistance as well as reduce capacity. It is based on full charge and discharge cycles, plotting a graph of the internal resistance and battery capacity over the course of the inputted cycles. The model allows users to track the true aging of the battery, and how these factors impact the state of health.
