The application relates to the field of batteries and discloses a solid-state electrolyte precursor and a lithium metal battery. The solid-state electrolyte precursor is characterized in that the solid-state electrolyte precursor comprises a ternary eutectic solvent, an ether monomer, a fluorine ether diluent and a lithium salt; the ternary eutectic solvent comprises lithium bistrifluoromethylsulfonylimide, a Lewis acid and a Lewis base; and the molar ratio of the lithium bistrifluoromethylsulfonylimide and the Lewis acid is 1:0.01-5. The solid-state electrolyte precursor contains a specific ternary eutectic solvent, a lithium metal battery containing a deep eutectic solid-state electrolyte obtained by in-situ polymerization of the solid-state electrolyte precursor has good interface stability, the generation of lithium dendrites is inhibited, the lithium metal cycle stability is high, and the safety performance is more excellent.

The invention relates to a converter steelmaking slag system for increasing the content of residual manganese in molten steel and a using method thereof, and belongs to the technical field of steelmaking processes. The slag system comprises the following components in percentage by mass: less than or equal to 4.0% of MgO, less than or equal to 4.5% of MnO, 40-50% of CaO, 12-18% of SiO2, less than or equal to 15% of FeO, Al2O3, CaF2, S and P2O5. By reasonably designing the components of the slag system, the addition of the slag making material light-burned dolomite containing the MgO component is reduced, MgO and MnO are prevented from generating a high-melting-point phase, and the high-melting-point phase is enriched in the slag to form a solid phase, so that MnO can be smoothly reduced by CO to enter the molten steel, and the content of residual manganese in the molten steel is increased.
