<P>PROBLEM TO BE SOLVED: To facilitate operations to manufacture an electrical accumulation device having an ion supply source. <P>SOLUTION: The electrical accumulation device includes an electrode stack unit 12 having a positive electrode 14 and a negative electrode 15 stacked, and includes a lithium electrode 16 at an outermost portion of the electrical stack unit 12. The positive electrode 14 has a positive electrode current collector 20 and a positive electrode mixture layer 21. The negative electrode 15 has a negative electrode current collector 22 and a negative electrode mixture layer 23. The lithium electrode 16 includes a lithium electrode current collector 26 welded to the negative electrode current collector 22 and a lithium unit 27 sandwiched between the lithium electrode current collector 26 and negative electrode 15. The lithium unit 27 comprises a lithium holding plate 27a coming into contact with the lithium electrode current collector 26 and a lithium ion supply source 27b provided thereto. The lithium electrode current collector 26 is stacked and welded alone without being provided with the lithium ion supply source 27b, so damage to the lithium ion supply source 27b is avoided and the manufacturing operations are facilitated. <P>COPYRIGHT: (C)2009,JPO&INPIT |
