  • Publication number: 20240170662
    Abstract: The present disclosure discloses a recycling method of a ternary material micropowder, and use thereof. The recycling method includes: washing the ternary material micropowder with water, and adding a coating agent and an promotor; subjecting a resulting mixture to a reaction under heating and pressurization, and filtering to obtain a coated base material; subjecting the coated base material to sintering, adding an extracting agent to a resulting sintered material, and stirring and filtering to obtain a filter residue; and subjecting the filter residue to drying, sieving, and iron removal to obtain a ternary cathode material. In the present disclosure, the coating agent and the promotor are added to achieve high-pressure hydrothermal coating for the micropowder. The coating agent can optimize the storage performance of the material and increase the life of the material.

  • Publication number: 20240128456
    Abstract: The invention belongs to the technical field of material synthesis, and discloses a nitrogen-doped hollow cobaltosic oxide and a preparation method and application thereof. A chemical formula of the nitrogen-doped hollow cobaltosic oxide is Co3O4—COF-T-D@C—N; and the COF-T-D is a covalent organic framework. Due to an open hollow structure, the nitrogen-doped hollow cobaltosic oxide of the invention has a large specific surface area, thus having a large contact area with an electrolyte, which is convenient for lithium ions to transport therein. The open hollow structure also prevents a volume effect from being generated during charging and discharging, and nitrogen is introduced for doping, so that granules can be gradually activated to increase the specific surface area and active sites, a discharge (cycle) stability of the material is improved, and a rate performance of the material is improved.
