In general, sulfides are less soluble in water compared to hydroxides. Sulfides are compounds that contain sulfur in the -2 oxidation state, such as iron sulfide (FeS) or lead sulfide (PbS). These compounds tend to form insoluble precipitates when dissolved in water. For example, if you try...

Indeed, during discharging of the Li-S battery, sulphur rebounds with lithium ions: the intermediate products are soluble long-chain polysulphides (Li2Sx, 4 ≤ x≤ 8) and the discharge products are insoluble short-chain polysulphides (Li2S2/Li2S) [50,51]. This migration/shuttle of soluble...
