Abstract

Abstract : In article number 2000493, Hee‐Tak Kim and co‐workers demonstrate the dual functionality of lithium nitrate in lean‐electrolyte lithium–sulfur batteries. Based on its high electron donicity, the nitrate anion enhances sulfur utilization and prevents electrolyte decomposition, enabling both high cycling capacity and long‐term stability of lean‐electrolyte lithium‐sulfur batteries.
