The present invention relates to an electrolyte solution for a lithium secondary battery, the electrolyte solution containing a lithium salt, an organic solvent and a thermosetting organic compound.n n n The lithium secondary battery using the electrolyte solution may be cured as the temperature of the added thermosetting organic compound increases, thereby preventing a reaction between the electrolyte and lithium, thereby preventing a risk of explosion of the battery due to temperature rise. In addition, since the electrolyte solution of the present invention further includes a pyrocarbonate compound, it is possible to provide a battery having improved initial charge and discharge life performance. |
