Description
Summary:Lithium‑sulfur batteries (LSBs) have emerged as a promising contender to replace conventional lithium-ion batteries (LIBs). Primarily due to their impressive advantages, including environmental friendliness, resource availability, and high energy density. However, the practical implementation of LSBs has been hampered due to some intrinsic problems, such as the instability of lithium metal anodes, low conductivity, and capacity fading. This review article explores the potential benefits of LSBs, clarifies research initiatives aiming at solving these problems, and considers possible applications. To give a current perspective on the improvements in LSB technology, breakthroughs in the sector are also included. This review helps to better grasp the advantages and challenges of LSBs by thoroughly analyzing both of those factors. It also assists in determining the right application domains. The culmination of previous research successes and failures highlights the value of ongoing innovation in advancing the development of LSBs towards commercial viability and integration into a range of energy storage applications.
