Abstract
A solid electrolyte battery produced by a recessed portion forming step of forming a recessed portion 10 having a predetermined shape and a predetermined depth at a predetermined position on a substrate a1 and by a laminating step of laminating the layers of a power-generating element f on the recessed portion 10. With this configuration, the height of portions projecting from the surface of the substrate can be limited significantly, and the step coverage on the upper layer can be improved, whereby it is possible to produce a solid electrolyte secondary battery being excellent in reliability.
Claims14
(Amended) A solid electrolyte battery comprising:
- one of a metal substrate, a semiconductor substrate, a glass substrate, a ceramic substrate and a resin substrate, having a recessed portion and
- one or more power-generating elements each having a first active material layer, a solid electrolyte layer and a second active material layer, wherein
- said power-generating element is disposed in said recessed portion, and the depth of said recessed portion is in the range of 0.3 to 1.0 time as large as the whole film thickness of said laminated power-generating element.
(Deleted)
(Unchanged) A method of producing a solid electrolyte battery, comprising a recessed portion forming step of forming a recessed portion having a predetermined shape and a predetermined depth at a predetermined position on one of a metal substrate, a semiconductor substrate, a glass substrate, a ceramic substrate and a resin substrate, and a laminating step of sequentially laminating said power-generating element layers on said recessed portion.
