The electrochemistry of stable sulfur isotopes versus lithium.

ABSTRACT: Sulfur in nature consists of two abundant stable isotopes, with two more neutrons in the heavy one (³⁴S) than in the light one (³²S). The two isotopes show similar physicochemical properties and are usually considered an integral system for chemical research in various fields. In this work, a model study based on a Li-S battery was performed to reveal the variation between the electrochemical properties of the two S isotopes. Provided with the same octatomic ring structure, the cyclo-³⁴S₈ molecules form stronger S-S bonds than cyclo-³²S₈ and are more prone to react with Li. The soluble Li polysulfides generated by the Li-³⁴S conversion reaction show a stronger cation-solvent interaction yet a weaker
