Redox Mo-chloro-species-coupled Se oxidation conversion in low-corrosion ionic liquids for fast-kinetics and durable Zn batteries

By incorporating in situ -activated redox Mo-chloro species into Se conversion reactions of the 1T-MoSe 2 cathode, a Zn–MoSe 2 battery with boosted kinetics and ultralong cyclability is initially achieved with a novel low-corrosion ionic liquid electrolyte.
