Abstract: An electricity-storing device includes a first electrode, a second electrode of opposite polarity as the first electrode, and a separator. The first electrode includes a current collector foil, an active material layer formed on at least one surface of the current collector foil, and an electrical resistance layer formed on the at least one surface of the current collector foil so as to be adjacent to and in direct contact with the active material layer, at least a portion of an interface between the active material layer and the electrical resistance layer including a mixed phase where constituents from the active material layer and the electrical resistance layer intermingle.
