Abstract
An electrochemical device includes: a positive electrode having a positive-electrode collector made of conductive material, and a positive-electrode active material layer formed on the positive-electrode collector; a negative electrode having a negative-electrode collector made of conductive material, and a negative-electrode active material layer formed on the negative-electrode collector; separators placed between the positive electrode and the negative electrode; and an electrolyte immersing the positive electrode, negative electrode, and separators. Metallic lithium is joined to a lithium-electrode collector, and the lithium-electrode collector is placed in a manner contacting the negative-electrode active material layer, and immersed in the electrolyte, so that the negative-electrode active material is pre-doped with lithium ions. The electrochemical device can offer high capacitance and excellent productivity.
