Abstract: The invention provides a method for increasing the quality of graphite balls. The method comprises melting molten iron in an electric furnace, increasing the sulfur content in the molten iron during the melting process, and adding rare earth in the electric furnace or in a nodularizing ladle; after the molten iron is completely melted, pouring the molten iron into the nodularizing ladle and nodularizing; and after nodularization, adding ferromanganese to a transfer ladle. In the present invention, sulfur is added to molten iron in advance, and rare earth is added to a nodularizing ladle previously, so that a large number of dispersed rare earth sulfide particles are formed in the molten iron during the nodularization process. Rare earth sulfide particles serve as the nuclei of graphite crystallization to increase the number of graphite balls, and improve the roundness of graphite balls.

Abstract: A lithium salt easily soluble in an organic solvent and having a flame-retardant function and a lithium-ion battery flame-retardant electrolyte thereof are provided. The lithium salt is poly(lithium phosphate) phosphazene partially substituted by alkyl aromatic oxy groups, and has a structural general formula: [(R—Ar—O)x(P═N)n(Li2O3P)2n-x]. The novel flame-retardant electrolyte is compounded from the lithium salt and a phosphate intermediate thereof [(R—Ar—O)x(P═N)n(R′2O3P)2n-x] according to a mass ratio of 10:1-1:1. The electrolyte is easily soluble in an organic solvent. A liquid electrolyte is prepared according to an amount of 8%-45% to obtain the novel flame-retardant liquid electrolyte. The liquid electrolyte has good lithium ion conductivity and good flame-retardant properties, and is used in lithium-ion batteries, lithium-sulfur batteries, lithium carbon fluoride batteries or lithium-oxygen batteries.

Abstract: The polyurethane flame retardant is prepared by compounding poly(diphosphophosphazene) (PDPP) and derivatives thereof, poly(diphosphate phosphazene) (MPDPP) (where M=Mg2+, Ca2+, transition metal ions, rare earth ions and the like) and poly(diphosphonic phosphazene). Since a phosphate group in the PDPP and an unreacted phosphate group in the MPDPP in the compound and an unreacted hydroxyl in the phosphate group may react with isocyanate, the flame retardant is a reactive flame retardant. Due to the reaction between the flame retardant and the isocyanate, the flame retardant is uniformly distributed in polyurethane and has a better flame-retardant effect. The flame retardant contains multiple flame-retardant components, namely polyphosphazene group, phosphate ester and phosphate salt. Due to the synergistic effect, the flame retardant has good flame-retardant properties, and can be used for various polyurethane materials.
