Abstract:
1. A method of preparing a lithium secondary battery, comprising: providing a positive electrode including a material that is capable of reversible intercalation/deintercalation of lithium ions as a positive active material; providing a negative electrode including a material that is capable of reversible intercalation/deintercalation of lithium ions as a negative active material; preparing an electrode assembly containing the positive and negative electrodes; putting the electrode assembly in a battery case; and injecting an electrolyte including a lithium salt; a solvent consisting essentially of at least one carbonate-based organic solvent and at least one aromatic hydrocarbon solvent; and an isoxazole compound of the formula (1): into the battery case to fabricate a lithium secondary battery.
