Abstract
Abstract The performance of Lithium–sulfur (Li–S) batteries is constrained by the migration of lithium polysulfide (LiPS), the slow conversion of LiPS, and the significant reaction barrier encountered during the precipitation/dissolution of Li 2 S throughout the discharge/charge cycle. In this contribution, the study presents Ni–Co dual‐atom catalytic sites on hollow nitrogen‐doped carbon (NiCoNC). Theoretical calculations and experimental data reveal that the dual‐atom catalysts (DACs) accelerate the kinetic conversion of LiPSs and facilitate the formation/decomposition of Li 2 S during discharging and charging, which minimizes LiPS migration. Consequently, the utilization of S/NiCoNC cathodes manifests a…
