Abstract
Lithium-sulfur batteries (LSBs) has emerged as one of the foremost intriguing energy storage systems in the last
decade, due to its higher energy density (ED), less expensive, and more environmentally friendly. However, the
interface chemistries of electrode–electrolyte such as the shuttling effect of polysulfide and inadequate dynamic
sulfur use have not yet been completely understood and managed when in operations, thus the employment of
single-atom catalysts (SACs) provides the possibility to address these problems through the proper identification
of structure–activity connexions and the chemical reaction processes at the atomic level. In this mini review, the
usage of incredibly active SACs is examined with applications in long-lifecycle, higher-energy LSBs, as well as the
possibility of SAC preparation using the atomic layer deposition (ALD) process to boost efficiency. Conclusively,
the significant problems and future prospects for enhanced SACs via ALD in LSBs development are also discussed.
