摘要： A pouch-type lithium secondary battery includes a battery unit having a positive plate, a separator, and a negative plate; a plurality of electrode tabs, drawn from the positive and negative plates, respectively; a case, formed with a space receiving the battery unit and with upper and lower sealing surfaces thermally fused to each other; and an insulating tape wrapping the electrode tabs, wherein a portion of the insulating tape interposed between the upper and lower sealing surfaces is thermally fused to the upper and lower sealing surfaces, and an end portion of the insulating tape is exposed outside the case together with the electrode tabs and positioned outside the upper or lower sealing surface after being folded. A portion of the insulating tape exposed outside the sealing surface of the case is extended and the extended portion of the insulating tape comes in contact with the end portion of the sealing surface after being folded. Therefore, preventing an electrical short circuit between the electrode tab and the intermediate layer of the metal case is achieved.
