Numerical Investigation of Cathode Structure Influence on Electrochemical Behavior of Lithium-Sulfur Battery

Nowadays, Lithium-Sulfur batteries are often considered as the next generation technology for energy storage systems. This article investigates the influence of the size of sulfur clusters present in the cathode on the battery overall electrochemical behavior. The properties of the cathode are studied by cyclic voltammetry simulations using a custom numerical model implemented into Ansys Fluent. The simulation is supplemented by experimental cyclic voltammetry measurements and images from a scanning electron microscope.
