Alrik Forslund*

Lithium-sulfur (Li-S) batteries are considered one of the most promising candidates for next-generation energy storage devices due to their high theoretical energy density and low cost. However, their practical application is limited by several issues, including poor cycle stability, low conductivity of sulfur, and the dissolution of lithium polysulfides during discharge. Recent advancements in nanotechnology have introduced nanostructured materials as a solution to enhance the performance of Li-S batteries. These materials are designed to improve the conductivity of sulfur and confine the polysulfides within the cathode to mitigate the loss of active materials. In this article, we review the recent progress in the design of nanostructured electrode materials for Li-S batteries, focusing on their role in enhancing electrochemical performance, cycle life, and energy efficiency. Key strategies for developing high-performance nanostructured electrodes are discussed, including the use of carbon-based materials, metal oxides, and nanocomposites. Furthermore, the challenges and future directions for the optimization of these materials are also explored.
