Abstract
A bipolar lithium secondary battery having a bipolar unit that includes a current collector with positive and negative electrodes formed on opposite sides thereof. The bipolar lithium secondary battery may prevent self-discharging and the generation of bypass currents by separating the electrolyte solutions adjacent to the electrodes having different polarities by a polymer film attached to the edge of the current collector, and by preventing the movement of the separated electrolyte solutions.
