ELECTRODE MATERIAL COMPRISING MOISTURE POWDER, ELECTRODE, METHOD FOR PRODUCING SAME, AND SECONDARY BATTERY PROVIDED WITH SAID ELECTRODE

Provided by the present disclosure is an electrode material (mixture) which exhibits good spreadability and in which the surface area of an electrode active material layer at the stage of a coating film prior to drying can be easily increased by press molding. A moisture powder for forming an electrode active material layer on an electrode current collector of a positive electrode or negative electrode disclosed here is constituted from aggregated particles that contain a plurality of electrode active material particles, a binder resin and a solvent, whereinat least 50% by number or more of the aggregated particles that constitute the moisture powder have the following properties:(1) a solid phase, a liquid phase and a gas phase form a pendular state or a funicular state; and(2) a layer of the solvent is not observed at the outer surface of an aggregated particle in electron microscope observations.
