Radical or Not Radical: Revisiting Lithium–Sulfur Electrochemistry in Nonaqueous Electrolytes

Tracking down trisulfur radical in lithium–sulfur batteries is reported. In nonaqueous electrolytes, dissociation of polysulfide dianions to radicals, and particularly trisulfur S3·−, is believed to play a key role in the performance of lithium sulfur batteries. While S3·− exists in only minor concentration in glymes, exacerbated dissociation in donor solvents allows full utilization of both sulfur and lithium sulfide.
