Abstract
Disclosed is a lithium secondary battery comprising a positive electrode including a material that is capable of reversible intercalation/deintercalation of lithium ions as a positive active material; a negative electrode including a material that is capable of reversible intercalation/deintercalation of lithium ions as a negative active material; and an electrolyte including a lithium salt, a carbonate-based organic solvent, and an isoxazole compound of the following formula (1):
Claims14
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.
