CONTINUOUS EXTRUDING KNEADER FOR PRODUCING MIXTURE FOR ELECTRODE ACTIVE MATERIAL LAYER, MIXTURE FOR ELECTRODE ACTIVE MATERIAL LAYER USING CONTINUOUS EXTRUDING KNEADER, ELECTRODE LAMINATE, AND METHOD FOR MANUFACTURING ALL-SOLID-STATE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a continuous extrusion kneader for producing a sufficiently kneaded mixture for an electrode active material layer.SOLUTION: There is disclosed a continuous extrusion kneader for producing a mixture for an electrode active material layer. The continuous extrusion kneader includes, from upstream toward downstream, a first supply section for supplying at least a part of a solid electrolyte, a first kneading section for kneading a material supplied from the first supply section to provide an intermediate mixture, a second supply section for supplying at least a part of an electrode active material to the intermediate mixture, and a second kneading section for kneading the intermediate mixture and the material supplied from the second supply section, in the order. The first kneading section includes: a forward kneading section for kneading the material supplied from the first supply section and conveying the material downstream; and a reverse kneading section for kneading the material supplied from the forward kneading section and applying a force to the material in the upstream direction.SELECTED DRAWING: Figure 1
