Progress and Perspectives of Organosulfur for Lithium–Sulfur Batteries

Abstract

Lithium–sulfur batteries (LSBs) with high theoretical capacity are regarded as the most promising candidates for next-generation energy storage systems. However, the low conductivity, high volume change, and shuttle effect need to be addressed before the commercialization of LSBs. Organosulfur with covalent C-S bonds can solve these problems when applied as different components of LSBs. Recent advances of application of organosulfur as cathodes, electrolytes, interlayers, and binders in LSBs are reviewed. Finally, the prospects for organosulfur are proposed from both the perspectives of mechanism understanding and practical applications.
