    摘要： Described are electrolyte compositions and electrochemical devices containing them. The compositions include an organosilicon compound, an imide salt and optionally LiPF6. The electrolytes provide improved high-temperature performance and stability and will operate at temperatures as high as 250 C. An electrolyte composition comprising, in combination: an organosilicon compound and an imide salt and optionally UPF6; wherein when subjected to cyclic voltammetry at a plurality of cycles ranging from about 3V to about 5V and using a cathode current collector comprising aluminum versus Li/Lit electrodes the composition exhibits an oxidative corrosion current of about 0.10 mA/cm2 or less for a second and subsequent cycles.
