A highly efficient polysulfide mediator for lithium–sulfur batteries [PDF]

Nature Communications, 2015
The lithium-sulfur battery is receiving intense interest because its theoretical energy density exceeds that of lithium-ion batteries at much lower cost, but practical applications are still hindered by capacity decay caused by the polysulfide shuttle.
