Electrode material, and electrode layer, battery, and electrochromic device using the electrode material

Abstract

The present invention provides an electrode material comprising at least one of metal compound powder and carbon powder, the powder having an average particle size of 50 μm or less and an activation energy Eα of 0.05 eV or less. Further, the powder preferably has hopping conduction characteristics at room temperature of 25° C. Furthermore, the powder preferably has an amount of oxygen defects of 1×1018 cm−3 or more. Still further, the powder preferably has a carrier density of 1×1018 cm−3 or more. Due to above structure, there can be provided an electrode material having a high storage capacity and a high charge/discharge efficiency.
