Using High Energy Density Material in Electrode Design Enhances Lithium Sulfur Batteries

To develop higher capacity batteries, researchers have looked to lithium sulfur batteries because of sulfur’s high theoretical capacity and energy density. But there are still several problems to solve before they can be put into practical applications. The biggest is the shuttling effect that occurs during cycling. To solve this problem and improve lithium sulfur battery performance, the researchers created a sandwich-structured electrode using a novel material that traps polysulfides and increases the reaction kinetics.
