Abstract:
An electrochemical device is constituted by a positive electrode, a negative electrode, and separators that are wound in such a way that the first principal face of the negative electrode and third principal face of the positive electrode are on the inner side of winding, while the second principal face of the negative electrode and fourth principal face of the positive electrode are on the outer side of winding, with the separators separating the positive electrode and negative electrode; wherein the second principal face has a first region opposed to the positive electrode via the separator and a second region on the outermost side of winding and not opposed to the positive electrode, the second region includes a first uncoated region where no negative electrode active material layer is formed, and a metal lithium is joined to the first uncoated region and immersed in electrolytic solution.

Claim (Index 1):
An electrochemical device, comprising:\n a negative electrode which is a metal foil constituted by a negative electrode collector having a first principal face and a second principal face on an opposite side of the first principal face, and also by negative electrode active material layers formed on the first principal face and second principal face; a positive electrode which is a metal foil constituted by a positive electrode collector having a third principal face and a fourth principal face on an opposite side of the third principal face, and also by positive electrode active material layers formed on the third principal face and fourth principal face; separators that insulate the positive electrode and negative electrode; and electrolytic solution that immerses the positive electrode, negative electrode and separators; where the positive electrode, negative electrode, and separators are stacked and wound in such a way that the first principal face and third principal face are on an inner side of winding, and the second principal face and fourth principal face are on an outer side of winding, with the separators separating the positive electrode and negative electrode; wherein: the first principal face of the negative electrode collector faces toward the fourth principal face of the positive electrode collector via the separator; and the second principal face of the negative electrode collector has:\n a first region where the negative electrode active material layer is formed, said first region facing toward the third principal face of the positive electrode collector via the separator, and \n a second region, other than the first region, on an outermost side of winding and not facing toward the third principal face of the positive electrode collector, wherein the second region includes a first uncoated region where the negative electrode active material layer is not formed, and the first uncoated region has a metal lithium joined thereto and is immersed in the electrolytic solution to pre-dope lithium ions into the negative-electrode active layer.
