<P>PROBLEM TO BE SOLVED: To provide an electrode sheet with sufficient strength, which can be laminated. <P>SOLUTION: A lithium-ion battery has a positive electrode sheet 7 having a resin film 1, an aluminum deposition layer 3 arranged on one face of the film 1, and a positive electrode active material layer 5 applied on the aluminum deposition layer 3, a both-side electrode sheet 6 having the film 1, a copper deposition layer 2 arranged on one face of the film 1, a negative electrode active material layer 4 applied on the copper deposition layer 2, an aluminum deposition layer 3 arranged on the other face of the film 1, and a positive electrode active material layer 5 applied on the aluminum deposition layer 3, and a group of batteries 18 in which a negative electrode sheet 8 having the film 1, the copper deposition layer 2 arranged on one face of the film 1, and the negative electrode active material layer 4 applied on the copper deposition layer 2 is laminated via separators 11. The group of batteries 18 is dipped in an electrolyte. <P>COPYRIGHT: (C)2009,JPO&INPIT |
