Materials, Design Consideration, and Engineering in Lithium-Sulfur Batteries

Groundbreaking researches in the field of electrochemistry have increased the longevity and electric power density of lithium-sulfur (Li-S) batteries in recent decades. Moreover, these batteries have been recognized as a viable alternative to the Li-ion battery and are expected to play a key part in high-energy-density electrochemical storage systems owing to its low cost, plentiful resources, environmental friendliness, and high energy density. In this chapter, particular focus is paid on research and developments pertaining to various issues in Li-S batteries such as sulfur cathode, separator, electrolyte, and Li anode. Finally, a future perspective on the development of high-performance Li-S batteries is discussed.
