Rechargeable Li–S and Na–S Batteries
Rechargeable lithium–sulfur (Li–S) batteries offer a promising next-generation energy storage solution, with the potential to deliver 2–3 times higher energy density compared to current state-of-the-art lithium-ion batteries. Despite this advantage, challenges such as polysulfide shuttling and inefficient sulfur redox conversion hinder their practical deployment. Our research focuses on developing advanced sulfur hosts, interlayers, and electrocatalysts to overcome these performance-limiting issues and enable stable, high-performance Li–S batteries.
In parallel, we are also extending our efforts toward sodium–sulfur (Na–S) batteries, leveraging similar strategies to address the unique challenges of this alternative and cost-effective battery chemistry.
