<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery that exhibits superior charge-discharge cycle characteristics. <P>SOLUTION: The nonaqueous electrolyte battery is structured to include: a positive electrode layer 1; a negative electrode layer 2; and a sulfide system solid electrolyte layer 3 for mediating the movement of lithium ion between both layers, wherein the positive electrode layer 1, solid electrolyte layer 3, and negative electrode layer 2 are sequentially stacked. Furthermore, an intermediate layer 4 for suppressing mutual diffusion between both layers near an interface of both layers is provided between the positive electrode layer 1 and solid electrolyte layer 3. When the battery is observed in a plane view, the formation area of the negative electrode layer 2 is smaller than the formation areas of the positive electrode layer 1 and solid electrolyte layer 3, and larger than or equal to the formation area of the intermediate layer 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
