Advanced interlayer structures as effective polysulfide barriers in lithium-sulfur batteries

Title : Advanced interlayer structures as effective polysulfide barriers in lithium-sulfur batteries

Abstract:

Lithium-sulfur batteries (LSBs) are a promising technology for electrochemical energy storage, particularly for portable electronics and electric vehicles due to their high theoretical energy density and cost-effectiveness of sulfur. However, they face limitations in rate capability and lifespan due to the sluggish conversion kinetics of sulfur and the soluble lithium polysulfide (LiPS) intermediate. In this presentation, we will discuss various approaches that utilize modified interlayers, especially mesoporous materials, to overcome the challenges associated with lithium-sulfur batteries (LSBs) and enhance their performance. These approaches have been proposed as potential solutions to improve the efficiency and overall capabilities of LSBs.
