Problems solved by technology

[0011] In order to prevent the anode connection phenomenon from occurring, an insulating tape may be attached to each of the negative electrode lead 1a facing each other and the boundary portion 1d between the lead film 1b and the pouch case 1c, but when the insulating tape is attached, an increase in Parts (insulating tape) used for insulation and need to increase the insulating tape attaching process in terms of process, so there is a loss in productivity
