Abstract
Provided is a method for manufacturing a laminated electrode body which is excellent in terms of productivity and production cost. The method for manufacturing a laminated electrode body disclosed herein includes the steps of: preparing a wound body having a flat portion and two curved portions by using a laminate formed of an elongated positive electrode, an elongated negative electrode, and an elongated separator that insulates the positive electrode and the negative electrode from each other; preparing an electrode laminate structure having two cut surfaces by cutting out and removing the two curved portions of the wound body; and removing active materials on the cut surfaces of the electrode laminate structure by spraying an inactive gas or electrically insulating particles onto the cut surfaces while applying, to the electrode laminate structure, a voltage of 25 V or more and less than a voltage causing a dielectric breakdown of the separator.
