description A non-aqueous electrolyte and a lithium secondary battery using the same are provided, which satisfy both flame retardancy and charge-discharge cycle characteristics, and attain a longer lifetime of the battery. A mixture of a chain carbonate, vinylene carbonate, a fluorinated cyclic carbonate and a phosphate ester is used as the non-aqueous electrolyte. It is desirable that the phosphate ester includes trimethyl phosphate and a fluorinated phosphate ester. Further, it is desirable that ethylene carbonate is further contained.
