  • Sulfur composite cathode material and preparation method and application thereof
    Patent number: 10727480
    Abstract: A sulfur composite cathode material and a preparation method thereof. After a sulfur-containing suspension is mixed with a host material, the isolated sulfur of large particles is transformed into a uniform sulfur coating on the surface of the host material through the “solid-liquid-solid” phase transition process of elemental sulfur. The organic solvent is removed to obtain a sulfur composite cathode material; and the host material comprises a carbon material. By utilizing the dissolving-precipitating balance of the elemental sulfur in the selected organic solvent, through the strong interaction between the carbon material and the elemental sulfur dissolved in the organic solvent, the sulfur dissolved in the solution is continuously deposited on the surface of the host material, and the undissolved sulfur particles is continuously dissolved in the organic solvent, and then continuously deposited on the surface of the sulfur-carrying material, so as to obtain a uniform sulfur composite cathode material.
    Type: Grant
