Lithium-Sulfur Batteries: Materials, Challenges, and Applications presents the advantages of lithium-sulfur batteries, such as high theoretical capacity, low cost, and stability, while also addressing some of the existing challenges. Some of the challenges are low electrical conductivity, the possible reaction of sulfur with lithium to form a soluble lithium salt, the formation of the dendrimer, large volume variation of cathode materials during the electrochemical reaction, and shuttle behavior of highly soluble intermediate polysulfides in the electrolyte. This book provides some possible solutions to these issues through novel architecture, using composite materials, doping to improve low conductivity, etc., as well as emphasizing novel materials, architectural concepts, and methods to improve the performance of lithium-sulfur batteries. – Covers the state-of-the-art progress on materials, technology, and challenges for lithium-sulfur batteries- Presents novel synthetic approaches, characterizations, and applications of nanostructured and 2D nanomaterials for energy applications- Provides fundamentals of electrochemical behavior and their understanding at nanoscale for emerging applications in lithium-sulfur batteries
