KAUST team develops graphene-based method to make improved lithium-sulfur batteries

KAUST researchers have a layer of hierarchically three-dimensional porous graphene can greatly suppress polysulfide shuttling – a problem known to be holding back the development of lithium-sulfur batteries. This could potentially help create high-density batteries that are useful for various applications, like electric vehicles and more.

Li-S batteries have several potential advantages over the most commonly used types of batteries. They have a higher theoretical energy storage capacity and sulfur is a nontoxic element readily available in nature. Sulfur is also a waste product of the petrochemical industry, so it could be obtained relatively cheaply while increasing the sustainability of another industry.
