Zhejiang Huayou Recycling Technology Co., Ltd.

Core business segment of Huayou Recycling (Zhejiang Huayou Recycling Technology Co., Ltd.). Retired power batteries are collected, flexibly disassembled by automated pack-level dismantling, then crushed and sorted to produce black mass; through atmospheric plus pressure leaching hydrometallurgy combined with a pyro-hydrometallurgical priority lithium extraction technology, the black mass is regenerated into battery-grade nickel sulfate, cobalt sulfate, manganese sulfate and lithium carbonate, which flow back into ternary precursor and cathode material manufacturing, forming a closed loop of waste-for-materials. The company holds 45 patents related to black mass recovery and priority lithium extraction.

Co/Ni/Mn comprehensive recovery rate: >=98.5%; Lithium metal recovery rate: >=90%; Black mass yield: >=95%; Resource regeneration line processing capacity: 65000 t/a (retired power batteries); Output grade: battery grade

• Raw material for remanufacturing ternary precursors and cathode materials
