Enhanced Cycling Stability in Zn-Ion Batteries Using Aqueous-Organic Electrolyte Solvent Blends.

ABSTRACT: Zinc-ion batteries (ZIBs) have emerged as a promising candidate for safe and affordable energy storage. This is particularly true for ZIBs using aqueous electrolytes, but unfortunately, they suffer from severe degradation issues that have not been resolved despite of extensive research efforts in this field. Hybrid electrolytes using both water and dimethyl sulfoxide (DMSO) as a solvent are proposed, which combine the non-flammable properties of water-based electrolytes with the stability of solvent-based electrolytes. Further, this hybrid electrolyte allows for using tetrafluoroborate (Zn(BF₄)₂) as a salt, which readily corrodes Zn in aqueous formulations, but also contributes to a more stable SEI in the hybrid solvent system. These results are corroborated using Den
