Original Abstract

The lithium-sulfur batteries have the potential to become leading energy storage system as they are showing promising characteristics such as high theoretical capacity and energy density. However, their performance is hindered by poor cyclability, self-discharge and capacity loss. This paper presents a custom electrochemical model of a lithium-sulfur cell implemented into Ansys Fluent. With this model, a series of simulations of cyclic voltammetry were carried out. Cases for a planar electrode and a single particle were investigated. In order to evaluate the numerical results, they were compared to the experimental measurements.
