The invention discloses an electrode material with an intermediate Ti4O7 coating and belongs to the technical fields of hydrometallurgy and electrochemistry metallurgy. Titanium, aluminum and a titanium alloy or an aluminum alloy are taken as the inner core structure of an electrode, the surface of the electrode is coated with Ti4O7 which has excellent chemical performance such as low electrical resistivity, high activity, good electrochemical corrosion resistance and the like, so that the electricity conduction performance of the electrode is improved and an inner core material is protected; then a high-activity low-price metal oxide coating is prepared with an electroplating method or a high-activity rare metal oxide coating is prepared with a thermal decomposition method on the surface of the electrode. Current distribution of the electrode material is uniform, the purity of an electro-deposition product is high, the polarization potential of the composite electrode of the intermediate Ti4O7 coating is reduced by 70-188 mV than that of a traditional ti-based electrode, the current density is increased by 40-230 mA, the catalytic activity of the electrode is improved, the electrode potential is reduced in the practical use process, and energy conservation and consumption reduction are realized.
