Abstract
This slurry for secondary batteries includes inorganic particles, a binding material, and a dispersion medium. The inorganic particles are formed from a metal compound, including as main components, an alkali metal and a metal other than alkaline earth metals, the contained amount of the alkali metal being 0.001-2 mass %. A positive electrode according to an embodiment of the present invention is provided with a collector, an intermediate layer formed on at least one surface of the collector, and a mixture layer formed on the intermediate layer. The intermediate layer includes the inorganic particles, a binding material, and a conductive material.
