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

摘要

Disclosed is an electrolyte. The electrolyte includes an amide compound and an ionizable lithium salt. The amide compound has a specific structure in which an amine group is substituted with at least one alkoxyalkyl group and at least one halogen atom is present. The electrolyte has good thermal and chemical stability, a low resistance and a high ionic conductivity. In addition, the electrolyte has a high upper limit of electrochemical window due to its improved oxidation stability. Therefore, the electrolyte can be useful for the fabrication of an electrochemical device. Further disclosed is an electrochemical device including the electrolyte.
