CELL STACKING METHOD FOR SECONDARY BATTERY AND CELL STACK FOR USING THE SAME

The present invention relates to a cell stacking method for the inside of a secondary battery for manufacturing a cell stack having a structure in which a first electrode plate and a second electrode plate are alternately inserted and laminated into a folded part of a separation membrane which is formed by being folded in a zigzag shape, and comprises: a separation membrane supplying step which continuously supplies the separation membrane; a first laminating step which laminates the first electrode plate on one side of the separation membrane, and laminates the second electrode plate on the other side of the separation membrane; a first rotating step in which an electrode laminating body, formed by laminating the first electrode plate, the separation membrane and the second electrode plate in order, is rotated 180 degrees toward a predetermined direction around the axis of rotation which is perpendicular to the supplying direction of the separation membrane; a second laminating step in which the first electrode plate is laminated on one side and the second electrode plate is laminated on the other side, in a state in which one side and the other side of the electrode laminating body are laminated with the separating membrane after rotating 180 degrees toward in one direction; a second rotating step in which the laminating body laminated in the second laminating step is rotated 180 degrees in the opposite direction of the rotating direction of the first rotating step.
