Provided are an electrolyte for a lithium battery and a lithium battery including the electrolyte. Electrolytes for lithium batteries include non-aqueous organic solvents and lithium salts including lithium hexafluorophosphate (LiPF 6 ), lithium bisfluorosulfonimide (LiFSI), and lithium tetrafluoroborate (LiBF 4 ), wherein based on 1 mole ( mol) of LiPF 6 , the amount of LiFSI is in the range of about 0.01 mol to about 1.2 mol, and the amount of LiBF 4 is in the range of about 0.05 mol to about 0.7 mol. By using the electrolyte for a lithium battery, the service life characteristics and high temperature characteristics of the lithium battery can be improved. |
