<P>PROBLEM TO BE SOLVED: To provide a lithium battery in which a positive electrode layer is hardly separated from a positive electrode current collector accompanied with charge and discharge of the battery. <P>SOLUTION: The lithium battery 1 has an inclusion layer 12, a positive electrode layer 13, an SE (solid electrolyte) layer 14, and a negative electrode layer 15 laminated in this order on a positive electrode current collector 11. The inclusion layer 12 is arranged between the positive electrode current collector 11 and the positive electrode layer 13 and improves adhesion of both the positive electrode current collector and the positive electrode layer. The inclusion layer 12 is constructed of a compound containing both a metal element contained in the positive electrode layer 13 and a metal element contained in the positive electrode current collector 11 and has the same crystal structure as that of the positive electrode layer 13. By selecting the composition of the inclusion layer 12 as above, the inclusion layer 12 having good adhesion to both the positive electrode current collector 11 and the positive electrode layer 13 can be made. As a result, the lithium battery in which the positive electrode layer 13 is hardly separated from the positive electrode current collector 11 accompanied with charge and discharge of the battery can be made. <P>COPYRIGHT: (C)2009,JPO&INPIT |
