  • Patent number: 12252414
    Abstract: The present disclosure discloses a method for preparing a ternary cathode precursor material with low sulfur content and high specific surface area, and belongs to the field of lithium ion battery materials. In the present disclosure, by using a continuous filter with a spraying device for concentrating a reaction material, sulfur impurities can be uniformly removed in a reaction stage, and neither are the reaction environment and the production efficiency affected, nor does introduction of new impurities occur. In addition, by removing the mother liquor by means of negative pressure suction filtration, the material can be oxidized uniformly in a controlled manner, and the specific surface area of the ternary cathode precursor material is uniformly increased, so that during sintering, lithium ions more easily enter the interior of particles of the ternary cathode precursor material, thus exerting a higher capacity.
