[Solid-state battery: Huasheng Lithium Battery states it has mastered preparation processes such as solid-phase and liquid-phase methods for lithium sulphide] On June 23, 2025, Huasheng Lithium Battery released a record of investor relations activities, announcing that it had mastered the preparation processes for lithium sulphide, including solid-phase and liquid-phase methods. Leveraging its technological advantages in synthesis, purification, and solvent recovery, the company chose the liquid-phase method to prepare high-purity lithium sulphide, which offers the advantages of high purity, high yield, and good processing performance. Based on this high-purity lithium sulphide, the solid-state electrolyte Li6PS5Cl, jointly developed by the company and its customers, achieved an ionic conductivity of 5.57 ms/cm. In the future, Huasheng Lithium Battery will explore the mass production of lithium sulphide while refining its processes, and research a new generation of sulphide solid-state electrolytes with high conductivity and high mechanical strength.
