Rechargeable lithium-sulfur (Li-S) batteries have been considered as a potential energy storage system due to their high theoretical specific energy. However, their practical commercial application has been hindered by unresolved key issues. One promising approach to overcoming these challenges is the development of anchoring materials with exceptional performance. In this work, we conducted detailed evaluations of twelve types of MA 2 Z 4 (M = Ti, Zr, or Hf; A = Si or Ge; and Z = P or As) monolayers as potential Li-S battery electrodes through first-principles calculations. Our results indicate that these monolayers can effectively immobilize Li 2 S n species, preventing them from dissolving into the electrolyte and preserving intact Li 2 S n conformations. The high electrical conductivity of these monolayers can be perfectly retained after S 8 /L 2 S n clusters adsorption. Furthermore, the MA 2 P 4 monolayers demonstrate superior catalytic performance for the sulfur reduction reaction (SRR) compared to the MA 2 As 4 counterparts, whereas the MA 2 As 4 monolayers exhibit lower decomposition energy barriers. Our current work indicates that these MA 2 Z 4 monolayers hold significant promise as electrode materials for Li-S batteries.
