摘要： An electrode assembly includes alternately stacked electrodes and separator sheet portions of a separator sheet. The electrodes include a first and second electrodes. The separator sheet has a zigzag shape. The second electrode is shorter than the first electrode. A side surface wrapped by the separator sheet between opposing side surfaces of the first electrode and a side surface wrapped by the separator sheet between opposing side surfaces of the second electrode are respectively spaced apart from the separator sheet. An opposite side surface between the opposing side surfaces of the first electrode protrudes further than the separator sheet from the side surface of the second electrode. A separation distance between the separator sheet and the side surface of the second electrode is equal to or shorter than a distance by which the first electrode protrudes further than the second electrode from the side surface of the second electrode.
