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. Bottom: Schematic of Li-S cell using MCM to encapsulate liquid polysulfides at the sulfur electrode. C = Charge, D = Discharge.
