▎ 摘  要

NOVELTY - Preparation of a material capable of removing alkali metal ions involves providing electrode reaction device, fixing the dereactive precursor in the storage tank, mixing the medium and the electrolyte to obtain a mobile phase, which is placed in a storage tank, leaving the storage tank, making the medium material contact with the dereactable precursor, a redox reaction occurs, and a portion of the dereactable precursor is reduced to obtain a material that can dealkali metal ions, and the medium material is oxidized at the same time, starting the power device, adjusting the power supply device to the discharge state, the oxidized mediator flows into the positive electrode of the electrode reaction device, and is restored to the mediator by reduction, medium material flows into the storage tank, contacts with the dereactive precursor, and a redox reaction occurs, repeated until the dealkable precursor is completely converted into a dealkalizable metal ion material. USE - Preparation of removable/embedded alkali metal ion material used as anode and cathode material for lithium-ion secondary battery. ADVANTAGE - The method is simple, easy for industrial production, and provides the alkali metal ion material with high yield, and improved coulomb efficiency of alkali-metal ion secondary battery.
