Abstract

The invention provides an aqueous rechargeable sodium-ion capacitor battery based on a titanium phosphorus oxide cathode material. The aqueous rechargeable sodium-ion capacitor battery based on a titanium phosphorus oxide cathode material comprises a positive electrode, a negative electrode, a separator and electrolyte. The positive electrode comprises a sodium manganese oxide, conductive agent and adhesive. The negative electrode comprises a titanium phosphorus oxide, conductive agent and adhesive. The electrolyte is inorganic salt water-soluble solution containing sodium ions. The sodium manganese oxide and the titanium phosphorus oxide are obtained by the steps of raw material mixing, grinding, tablet pressing and calcining. The aqueous rechargeable sodium-ion capacitor battery based on a titanium phosphorus oxide cathode material has higher energy efficiency, higher power density, a longer cycle life and higher utilization rate of active materials than lead-acid batteries, and is cheaper, safer and more environment-friendly than cadmium-nickel batteries and hydrogen-nickel batteries. The preparation process is simple, and the battery can be prepared directly in the air. The battery has low requirement for the environment, has a wide range of material sources, is low in cost, and is suitable for industrialized mass production.
