Manufacturing method of stacked electrodes by winding type electrode stacking and stacked electrode thereby

PURPOSE: A method for manufacturing winding type stacked electrodes and the stacked electrode manufactured thereby are provided to improve input and output characteristics and to prolong a lifetime of a battery through a separation film with constant tension. CONSTITUTION: A method for manufacturing winding type stacked electrodes comprises the steps of: laminating a first electrode(121) at one side of a separation film(110) with constant tension in both directions, and a second electrode(122) at the other side, to form a unit electrode(130); winding the unit electrode at an angle of 180° around a rotary shaft vertical to a long direction of the separation film; laminating a third electrode on the separation film of the outside of the first electrode and a fourth electrode on the separation film of the outside of the second electrode and winding at an angle of 180° around the same rotary shaft, to obtain a second stack; and laminating a predetermined number of electrodes to obtain final electrode stacks.
