Abstract
A lithium secondary battery, in which, by using different electrolytes in a positive electrode and a negative electrode, and using a gel polymer electrolyte, in which a small amount of an electrolyte liquid is impregnated into a polymer matrix, between the negative electrode and the separator, the stability and performance of the electrode may be improved, and therefore, the performance and lifetime of the lithium secondary battery may be enhanced.
