ELECTRODE ASSEMBLY AND LITHIUM SECONDARY BATTERY COMPRISING SAME

摘要

The present invention relates to an electrode assembly, and more particularly, to an electrode assembly in which a plurality of unit cells having a stacking structure are positioned on a long sheet-type separation film and then wound. The unit cells are of two or more types according to the composition of an electrode. Both sides of the separation film stacked onto the unit cells having a stacking structure are coated with a coating material, and one side of the long sheet-type separation film is coated with the coating material. Thus, the electrode assembly of the present invention may reduce the initial resistance during the manufacture of a battery and improve processability in the manufacture of the battery and simultaneously maintain a battery life equivalent to conventional batteries. The present invention also relates to a lithium secondary battery comprising the electrode assembly.
