Title: ELECTRODE LAMINATE AND ALL SOLID LITHIUM CELL
Abstract:
The present invention provides a method of obtaining an electrode laminate of an electrode layer and a separator layer with which, even when a laminate of the electrode layer that contains a composite salt of lithium and titanium as an electrode active material and the separator layer is sintered at 600°C or greater, a side reaction of the electrode active material and the solid electrolyte does not occur during sintering. Used is an electrode laminate made by laminating the electrode layer containing the electrode active material and the separator layer containing a solid electrolyte in this order, the electrode laminate being characterized in that the electrode active material is a composite oxide of lithium and titanium, and that the solid electrolyte contains lithium phosphate and/or lithium niobate. Also, the electrode layer may also be an electrode composite layer containing: an electrode active material, and a solid electrolyte that is a perovskite-type oxide containing lithium.
