| Zusammenfassung: | To provide an all-solid battery that makes it unlikely for a positive electrode active material layer and a negative electrode active material layer to come into contact with each other even when the positive electrode active material layer or the negative electrode active material layer expands during charging and discharging.SOLUTION: In an all-solid battery, a positive electrode active material layer is laminated on one side of a solid electrolyte layer, and a negative electrode active material layer is laminated on the other side, and the solid electrolyte layer protrudes from the positive electrode active material layer and the negative electrode active material layer by 50 μm or more and 1000 μm or less in the direction intersecting the stacking direction.SELECTED DRAWING: Figure 2
【課題】充放電時に正極活物質層や負極活物質層が膨張した場合でも、正極活物質層と負極活物質層とが接触し難い全固体電池の提供。【解決手段】固体電解質層の一方面側に正極活物質層、他方面側に負極活物質層が積層されており、前記固体電解質層が、前記正極活物質層及び前記負極活物質層よりも、積層方向と交差する方向に５０μｍ以上１０００μｍ以下突出している、全固体電池。【選択図】図２ |
