Employing S(-I)/S(-II) Redox Chemistry in Quasi-1D Niobium Trisulfide-Graphene Cathodes for High-Capacity Magnesium-Lithium Hybrid Ion Batteries.

ABSTRACT: Magnesium-lithium hybrid ion batteries (MLIBs) offer a compelling alternative to traditional lithium-ion batteries (LIBs) due to their enhanced safety, abundant magnesium resources, and high theoretical capacities. However, their practical deployment is constrained by the scarcity of high-capacity cathode materials. Herein, we report a quasi-one-dimensional (1D) pseudolayered niobium trisulfide (NbS₃), incorporated with graphene, as a novel cathode that leverages disulfide (S₂^2-) redox chemistry to achieve remarkable electrochemical performance. The electrode exhibits excellent cycling performance, retaining high lithium/magnesium cointercalation capacities of 251 mA h g^-1 after 150 cycles at 100 mA g^-1 and 181 mA h g^-1 over
