Recent advances in the cathode materials and solid-state electrolytes for lithium sulfur batteries

Abstract

Lithium-sulfur batteries (LSBs) have sparked a lot of attention due to their high theoretical energy density and cost-effectiveness. However, several challenges, notably unstable cycle life and low sulfur consumption, have hampered the development of workable LSBs for commercial use. Most of these challenges arise from the cathode materials and liquid electrolytes. This mini-review attempts to highlight the current advancements in cathode materials and solid-state electrolytes for the development of next-generation LSBs.
