Anionic redox reaction in layered NaCr2/3Ti1/3S2 through electron holes formation and dimerization of S–S
Abstract
Anionic redox reactions are gaining interest as a means to optimize capacities of alkaline ion batteries. Here, the authors investigate various charge compensation mechanisms and report S–S dimerization and the formation of electron holes on sulfur in a model sulfide cathode.
