Abstract
A lithium secondary battery includes a plurality of electrode cells, each of which includes a first electrode, a second electrode having a different polarity from that of the first electrode and a separation layer interposed between the first electrode and the second electrode, and at least one ion permeation barrier between neighboring ones of the electrode cells. The ion permeation barrier has an air permeability less than that of the separation layer.
