USC team uses mixed conduction membranes to suppress polysulfide shuttle in Li-S batteries

Green Car Congress

One of the major issues hobbling the commercialization of high energy-density lithium-sulfur batteries is the “polysulfide shuttle”—the shuttling of polysulfide ions between the cathode and anode. The polysulfide shuttle is a major technical issue that limits the electrical performance and cycle life of this type of battery.
