ABSTRACT:
This invention relates to a non-aqueous electrolyte including: a first solute; a second solute; and an organic solvent dissolving the first solute and the second solute. The first solute is a salt having at least one fluorine atom in an anion moiety thereof, and the second solute is an inorganic borate having at least one boron atom and at least one oxygen atom in an anion moiety thereof. The inclusion of the second solute in the non-aqueous electrolyte makes it possible to reduce the amount of gas produced even if an electrochemical device including the non-aqueous electrolyte is stored at high temperatures. It is also possible to improve the high-rate discharge characteristics and discharge cycle characteristics.
