Zusammenfassung: | To provide an electrode material for a power storage device, which compensates for the defects of a hydrophobic active material, imparts hydrophilicity to the hydrophobic active material, and exhibits excellent dispersibility without deteriorating the electrode characteristics.SOLUTION: An electrode material for a power storage device using a non-aqueous electrolyte includes a composite powder, both an A component and a B component in one particle constituting the composite powder, the particle has a structure in which the B component is carried, coated, or exposed on the surface of the A component, and the component A is made of a material capable of electrochemically absorbing and releasing an alkali metal ion, and the component B is a sulfur-modified cellulose having at least a SOgroup as a functional group, and the content of the component B is 0.01 mass% or more based on 100 mass% of the total amount of the A and B components.SELECTED DRAWING: Figure 1
