Embodiment Construction

[0079] [solid battery]

[0080] The present invention provides solid batteries. The "solid battery" mentioned in this specification refers to a battery whose components (especially the electrolyte layer) are made of solid in a broad sense, and refers to an "all-solid battery" whose components (especially all components) are made of solid in a narrow sense. The "solid battery" described in this specification includes a so-called "secondary battery" that can be repeatedly charged and discharged, and a "primary battery" that can only be discharged. The "solid battery" is more preferably a "secondary battery". "Secondary battery" is not limited to its name, and electrochemical devices such as "electric storage device" may also be included.

[0081] "Plan view" in this specification refers to the state when the object is observed from the upper side or the lower side along the lamination direction D (or the thickness direction of the solid battery) of the layers constituting the ...

Abstract

The present invention provides a solid battery in which a connection failure between an electrode layer (that is, a positive electrode layer and / or a negative electrode layer) and an end surface electrode can be more sufficiently suppressed. The present invention relates to a solid battery having a stacked structure in which one or more positive electrode layers and one or more negative electrode layers are alternately stacked on each other with a solid electrolyte layer interposed therebetween, wherein: said solid battery has the end surface electrodes of positive and negative electrodes at the end surfaces of the stacked structure; and at least ones of the positive electrode layers and the negative electrode layers have a protrusion shape, which projects toward the end surface electrode side having the same polarity as the one of the positive electrode layers and the negative electrode layers, at the end of the end surface electrode side having the same polarity as the one of the positive electrode layers and the negative electrode layers, in a section view, and are electrically connected to the end surface electrode having the same polarity as the one of the positive electrode layers and the negative electrode layers.

Description

technical field [0001] The invention relates to a solid battery. Background technique [0002] In recent years, the demand for batteries as power sources for portable electronic devices such as mobile phones and portable personal computers has been increasing. In batteries used in these applications, an electrolyte (electrolyte solution) such as an organic solvent has been used as a medium for moving ions. However, in the battery having the above configuration, there is a risk of leakage of the electrolytic solution. In addition, organic solvents and the like used in electrolytic solutions are flammable substances. Therefore, it is required to improve the safety of the battery. [0003] Therefore, in order to improve the safety of the battery, research is being conducted on a solid battery using a solid electrolyte instead of an electrolytic solution as an electrolyte. [0004] As a solid battery, for example, Patent Document 1 discloses a solid battery having a laminate...
