Title:
SOLID ELECTRODE LAYER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2023180588
Kind Code:
A
Abstract:
To provide a solid electrode layer that has enabled a constitution In which a solid electrolyte material and a positive electrode active material are evenly and homogeneously dispersed in a positive electrode layer, using, as an invention target material, a layered rock salt-type oxide, which is a positive electrode active material that not only suppresses generation of impurities during sintering with a solid electrolyte layer, but also can be expected to achieve performance as high as applicable to a current all-solid-state lithium-ion secondary battery.SOLUTION: A solid electrode layer includes a lithicone type oxide and a layered rock salt type oxide. Therein: a content of impurities calculated from an X-ray diffraction diagram of the solid electrode layer is 1.0 mol% or less based on 100 mol% of a total amount of the solid electrode layer; an average diameter of shapes obtained by performing Voronoi division on the layered rock salt type oxide is 0.50 to 2.00 μm; and a standard deviation of the average diameter of the shapes obtained by performing Voronoi partitioning on the layered rock salt type oxide is 1.00 μm or less.SELECTED DRAWING: None
