摘要
Lithium-sulfur(Li-S) battery, with an ultra-high theoretical energy density of 2600 Wh/kg, is inevitably deemed as one of the most promising alternatives for the state-of-the-art lithium-ion(Li-ion) batteries [1]. As a typical conversion-type of batteries, Li-S batteries comply multi-electron transfer and multiphase transformation between elemental S and lithium sulfide(Li_(2)S) during charging/discharging, accompanied by a series of dissolved LiPSs with a general formula of Li_(2)Sn(n=4, 6 or 8) [2].
