Abstract

A primary objective of the present invention is to provide a solid cell with which it is possible to alleviate short-circuits between electrodes. The present invention is a solid cell, comprising a first electrode layer, a second electrode layer, and a solid electrolyte layer which is positioned between the first electrode layer and the second electrode layer. A first insulation layer is positioned upon the exterior circumference of the first electrode layer. The size of the stack face of the first electrode layer, taking the stack direction of the first electrode layer, the solid electrolyte layer, and the second electrode layer as the direction of the normal thereof, is smaller than the size of the stack face of the solid electrolyte layer. When viewed from the stack direction, the outer edge of the solid electrolyte layer is located upon the exterior circumference of the first electrode layer, and the outer edge of the first insulation layer is located on the exterior circumference of the solid electrolyte layer. The first electrode layer, the first insulation layer, and the solid electrolyte layer are positioned such that the outer edge of the first insulation layer and the end parts of the solid electrolyte layer make contact.

Description

technical field [0001] The present invention relates to a solid battery comprising a pair of electrode layers and a solid electrolyte layer arranged between the pair of electrode layers. Background technique [0002] Lithium-ion secondary batteries (hereinafter sometimes simply referred to as “batteries”) are characterized by high energy density and the ability to operate at high voltages compared with other secondary batteries. Therefore, the secondary battery is used in information devices such as mobile phones as a secondary battery that can be easily reduced in size and weight. In recent years, the demand for large-scale power such as electric vehicles and hybrid vehicles has also increased. [0003] A lithium ion secondary battery includes a positive electrode layer and a negative electrode layer (a pair of electrode layers) and an electrolyte layer arranged therebetween. As an electrolyte used for the electrolyte layer, for example, a non-aqueous liquid or solid substa...
