Abstract
A wound-type accumulator is equipped with a cylindrical wound electrode unit, which has belt-like positive electrode and negative electrode and configured by winding an electrode stack obtained by stacking the positive electrode and negative electrode through a separator from one end thereof, and an electrolytic solution. The negative electrode and/or the positive electrode is doped with lithium ions by electrochemical contact of the negative electrode and/or the positive electrode with a lithium ion source, intra-positive electrode spaces are formed in the positive electrode, and at least one lithium ion source is provided in the intra-positive electrode space or at a position opposing to the intra-positive electrode space in the negative electrode in a state coming into no contact with the positive electrode.
