NOVELTY - Non-lithium aqueous alkaline double-ion battery comprises an anode, a cathode and alkali electrolyte. The anode comprises an anode current collector and an anode material arranged on the surface of the anode current collector. The cathode comprises a cathode current collector and a cathode material arranged on the surface of the cathode current collector. The anode material comprises hydrotalcite materials, hydrotalcite-carbon composite materials and nickel-based materials. The cathode material comprises sodium titanium phosphate, sodium titanium phosphate doping compound, poly 1,5-diaminoanthraquinone or a composite material containing sodium titanium phosphate. The alkaline electrolyte comprises an alkaline aqueous solution containing sodium ions or an alkaline aqueous solution containing potassium ions. USE - Used as non-lithium aqueous alkaline double-ion battery. ADVANTAGE - The non-lithium aqueous alkaline double-ion battery is safe, low cost, and has high efficiency electric energy storage.
