ELECTROLYTE COMPRISING EUTECTIC MIXTURE AND ELECTROCHEMICAL DEVICE EQUIPPED WITH SAME

摘要

The present invention discloses (a) an amide compound containing an alkoxy alkyl group of a specific structure and a eutectic mixture of an ionisable lithium salt; and (b) an electrolyte containing a carbonate compound. Due to its eutectic mixture content, the electrolyte of the present invention displays excellent thermal stability, chemical stability and a low value for the lower limit of the electrochemical window. Additionally, the present invention is used effectively as an electrolyte in electrochemical devices employing various anodic materials because it exhibits sufficiently low viscosity and sufficiently high ion conductivity.
