COMPOSITE ELECTRODE AND ALL-SOLID LITHIUM BATTERY
To provide an electrode which allows many electrode active materials that are contained in an electrode to make contribution to charge and discharge by cutting a solid electrolyte making no contribution to formation of a lithium ion-conducting path, and which has a capacity closer to a theoretical capacity in comparison to a conventional one.SOLUTION: Provided is a composite electrode composed of a sintered compact containing an electrode active material and a solid electrolyte. The composite electrode is composed of an alternately-arranged laminate in which oxide-based electrode active material-containing sheet-like electrode active material layers and oxide-based solid electrolyte-containing sheet-like solid electrolyte layers are arranged so that the two kinds of layers alternate with each other. In the composite electrode, the electrode active material layer has a width of 10 nm or more and 20 μm or less, and the solid electrolyte layer has a width of 10 nm or more and 20 μm or less. The solid electrolyte layer extends through the composite electrode.SELECTED DRAWING: Figure 1
