  • Sodium ion storage material
    Patent number: 11217818
    Abstract: The present disclosure relates to a sodium-ion storage material and an electrode material for a sodium-ion battery, an electrode material for a seawater battery, an electrode for a sodium-ion battery, an electrode for a seawater battery, a sodium-ion battery, and a seawater battery, which include the sodium-ion storage material. Specifically, the sodium-ion storage material may include one or more materials selected from the group consisting of CuxS, FeS, FeS2, Ni3S, NbS2, SbOx, SbSx, SnS and SnS2, wherein 0<x?2. When the sodium-ion storage material according to the present disclosure is used, it may exhibit high discharge capacity, and when the sodium-ion storage material is applied to a sodium-ion battery which is a secondary battery, it may exhibit excellent charge/discharge cycle characteristics.

  • Metal-Doped Sodium Vanadium Fluorophosphate/Sodium Vanadium Phosphate (Na3V2(PO4)2F3/Na3V2(PO4)3) Composite for Sodium-Ion Storage Material
    Publication number: 20210242451
    Abstract: The present disclosure relates to a sodium-ion storage material including a doped compound, and an electrode material for a sodium-ion battery, an electrode for a sodium-ion battery, and a sodium-ion battery, which include the sodium-ion storage material. Specifically, the sodium-ion storage material may include a compound consisting of an Na3V2-xMx(PO4)2F3/Na3V2-yMy(PO4)3 composite (M=Fe, Mn, Cr, Cu, Zn or Ti, 0<x,y?2). When the sodium-ion storage material according to the present disclosure is used, it may maintain high discharge capacity while reducing the vanadium content, and when the sodium-ion storage material is applied to a sodium-ion secondary battery or a sodium-magnesium hybrid-ion battery, the battery may exhibit excellent charge/discharge cycle characteristics.

  • APPARATUS AND METHOD FOR CONSTRUCTING LIBRARY FOR DERIVING MATERIAL COMPOSITION
    Publication number: 20210166791
    Abstract: An apparatus for constructing a library for deriving a material composition using empirical result, which enables acceleration of research on the material-properties relationship. By applying the empirical results of the material composition, missing data of the material compositions can be statistically calculated by using supervised non-linear imputation techniques. The completed composition information of the materials is passed as an input of machine learning material-properties relationship prediction.
