Abstract
A lithium secondary battery includes a cathode including a cathode current collector and a cathode active material layer formed on the cathode current collector, and an anode including an anode current collector and an anode active material layer formed on the anode current collector. The anode active material layer has an area larger than that of the cathode active material layer. The anode active material layer includes an overlapping portion overlying the cathode active material layer in a planar direction and a margin portion around the overlapping portion. The margin portion has an electrical resistance greater than that of the overlapping portion.
