Abstract:
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.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
