ELECTROLYTE COMPRISING AN AMIDE COMPOUND, AND ELECTROCHEMICAL DEVICE COMPRISING THE ELECTROLYTE

摘要

The present invention relates to an electrolyte comprising an amide compound having a specific structure, in which an amine group is substituted by an alkoxy alkyl group, and which comprises: a halogen; and ionizable lithium salts. The present invention also relates to an electrochemical device comprising the electrolyte. The electrolyte of the present invention has superior thermal stability, chemical stability, low viscosity, and excellent ion conductivity. In addition, the electrolyte of the present invention has improved oxidative stability to raise the upper limit value of an electrochemical window, and thus can be valuably used as an electrolyte for an electrochemical device.
