Abstract
An electrochemical device includes a first electrode unit; a second electrode unit; a third electrode unit; a first lithium ion supply source, which is disposed between the first electrode unit and the third electrode unit and includes a first current collector that is a porous metal foil having a first main surface on the side of the first electrode unit; a second lithium ion supply source, which is disposed between the second electrode unit and the third electrode unit and includes a second current collector that is a porous metal foil having a third main surface on the side of the second electrode unit; and an electrolyte. Lithium ions are pre-doped from first metal lithium attached to the first main surface, and second metal lithium attached to the third main surface, into the negative electrode of each electrode unit.
