abstract |
The present invention relates to an electrolyte and a lithium secondary battery comprising the same, wherein the electrolyte is a first electrolyte system comprising a carbonate-based solvent and LiPF 6 , and a first electrolyte system comprising a propionate-based solvent, a difluorophosphate, And a second electrolyte system comprising 3,6-hexanetricarbonitrile. The electrolyte has improved linear LSV (linear sweep voltametry) values, and does not lower the contact angle and Li + transference number on the surface of the anode relative to the commercial electrolyte. |
