PURPOSE: A non-aqueous electrolyte for lithium battery is provided to prevent electrolyte decomposition phenomenon at high potential, thereby enhancing rechargeable cycle characteristic. CONSTITUTION: A non-aqueous electrolyte for lithium battery can be obtained by adding sulfone-based organic solvent to electrolyte which includes lithium salt and carbonate based solvent. The non-aqueous electrolyte additionally includes anode film formation additives. The carbonate based solvent comprises one or more of cyclic carbonate based solvents selected from ethylene carbonate, propylene carbonate, and pentylene carbonate, and one or more of chain carbonate based solvents selected from dimethylcarbonate, diethyl carbonate, dipropyl carbonate, ethyl methyl carbonate, methylpropyl carbonate, and ethylpropyl carbonate. |
