摘要： An object is to provide a method for manufacturing an electrode composite slurry and a manufacturing device which can continuously manufacture an electrode composite slurry and suppress the production of faulty products. A method for continuously manufacturing a secondary cell electrode composite slurry is provided, and the method includes: a dispersing-kneading step of continuously dispersing and kneading the material of the electrode composite slurry; a first property measurement step of measuring the property of the electrode composite slurry that has been dispersed and kneaded; a redispersing-kneading step of redispersing and kneading the electrode composite slurry; and a property determination step of determining whether or not the redispersing-kneading step is performed based on the result of the measurement in the first property measurement step.

摘要： Provided is a secondary battery electrode having a sufficient peel strength between a base material and a material mixture layer without the need for increasing a binder addition amount. A secondary battery electrode includes a base material and a material mixture layer made of an electrode material mixture containing an active material and a binder. The material mixture layer has a multilayer structure of at least two or more layers stacked on the base material. In the multilayer structure of the material mixture layer, a first material mixture layer stacked on a surface of the base material has a higher contained binder concentration than those of other material mixture layers. The thickness of the first material mixture layer is preferably equal to or less than the total thickness of the other material mixture layers.
