New Energy Battery Industry

High-Purity Products and Technical Synergy

Core Needs and Pain Points

As a core raw material for sulfide solid-state electrolytes, lithium sulfide requires ≥99.99% purity, D50 ≤5μm particle size, and controllable specific surface area. Leaders like CATL and Huawei are accelerating sulfide tech R&D for post-2025 mass production.

Solutions

  • Product Strategy: Supply high-purity lithium sulfide ranging from 4N (99.99%) to 6N (99.9999%), covering laboratory R&D (50g-1kg packaging) and mass production needs (ton-scale supply). Support customization of particle size (D50=1-10μm) and specific surface area (1-5m²/g). For example, Guanghua Technology’s 6N-grade product costs only CNY 200,000/ton with a gross margin exceeding 90%, and has secured hundred-ton sample delivery partnerships with Qingtao Energy and Weilan New Energy.
  • Technical Support: Collaborate with battery manufacturers to optimize lithium sulfide synthesis processes (e.g., carbothermal reduction, liquid-phase methods) and provide material modification solutions (e.g., nitrogen doping for stability), assisting clients in pilot line verification.
  • Supply Chain Assurance: Strategic partnerships with upstream enterprises like Tianqi Lithium and Ganfeng Lithium ensure stable lithium resource supply; rapid capacity expansion through technological upgrades (e.g., Guanghua Technology’s current 300-ton capacity scalable to 3,000 tons) matches clients’ mass production schedules.
