Fluorinated carbamates as solvent for lithium-ion electrolytes

摘要

The present invention relates to an electrolyte solution comprising an electrolyte salt and an electrolyte solvent, wherein the electrolyte solvent comprises a fluorinated carbamate according to the general formula (1) R 1 R 2 NC(O)OCR 3 R 4 R 5 in an amount in the range from ‰¥ 80 wt% to ‰¤ 100 wt%, referring to a total amount of the electrolyte solvent of 100 wt%, and to a method for preventing aluminum current collector corrosion in alkali or alkaline earth metal-based or an Al-based or Zn-based electrochemical energy storage devices by using said electrolyte solution.
