Tóm tắt

The stability of the electrode-electrolyte interface in layered oxides is enhanced by electrolyte design criteria. A weakly-solvated electrolyte containing ethyl trifluoroacetate solvents with perfluorinated functional groups can restrain electrolyte decomposition and structural degradation when subjected to heat attack, exhibiting superior cycling durability at 60 °C compared to other fluorinated electrolytes.
