Abstract

A practically available strategy is employed to improve the cycle life of lithium-sulfur batteries. The simple process of activation cycling at the polysulfide dissolution region leads to the partial dissolution of polysulfides and the redistribution of sulfur on the electrode. After 50 cycles, the modified activation-cycled sulfur cathode exhibits a capacity that is roughly double that of a cathode without activation cycling.
