Exceptional catalytic effects of black phosphorus quantum dots in shuttling-free lithium sulfur batteries
Abstract
Lithium sulfur batteries are promising for next-generation energy storage, but are hindered by polysulfide shuttle effects. Here the authors use black phosphorus quantum dots to adsorb and catalyze the conversion of lithium polysulfides to lithium sulfide, achieving low capacity fade and high sulfur loading.
