MOF@rGO-based cathodes for Li-S Batteries - MOGLiS

Project summary

Lithium-sulfur (Li-S) batteries are attractive next generation energy storage devices in sectors like transportation due to their higher theoretical capacity and energy density. The lack of high-performance cathodes that can overcome the decay in cell capacity with cycling hinders the current market realization of Li-S batteries. The MOGLiS project aims at fabricating high performance cathode materials using novel MOF@rGO architectures with MOF decorated graphene-based nanosheets at nanoscale engineering cathodes carefully from the crafted chemistry and architecture with superior electrical properties and efficient immobilization of sulfur. Such flexible Li-S cathodes will be designed and demonstrated at TRL 4 for a high initial capacity >1300 mAh.g-1 and a reversible capacity, after 20 cycles, superior to 1200 mAh.g-1, but also a high cyclability with demonstrations >100 cycles with a capacity loss of less than 0.010% per cycle, for a sulfur loading in the cathode superior to 75%.
