MOF-74(M) (M = Mg(II), Fe(II), Ni(II)) frameworks to enable accelerated redox kinetics for Li-S batteries.

ABSTRACT: This study presents the development of a composite electrode material for lithium-sulphur (Li-S) batteries, combining MOF-74 with carbon black and sulphur. The MOF-74 structures, incorporating Ni(II), Mg(II), and Fe(II) metal ions, were synthesized via a solvothermal method and used to encapsulate sulphur. The microporous nature of MOF-74 facilitates the physical confinement and storage of sulphur, potentially enhancing the performance of Li-S batteries. The investigation focuses on how different central metal ions in MOF-74 influence the performance of sulphur-based electrodes. Among the metal ions studied, Fe(II) and Mg(II) were selected for their low toxicity, cost-effectiveness, and availability, while Ni(II) was included for its high catalytic properties. The materials were thoroughly
