Process Route & System Overview

A spent lithium battery recycling line typically consists of second-life applications, battery disassembly and crushing & sorting, black mass hydrometallurgical lithium extraction, and EHS support systems. By routing batteries at different value stages, we ensure safety and longevity in second-life scenarios while achieving efficient recovery and purification of lithium, nickel, cobalt, manganese, and other key metals from black mass.

For retired power batteries that still retain energy value, through testing and screening, module disassembly and cell regrouping, consistency evaluation and grading, we output second-life battery systems suitable for energy storage, low-speed electric vehicles, and other applications, maximizing value and enabling full lifecycle management.

For batteries unsuitable for second-life use or with safety concerns, we employ live/inert atmosphere crushing, sorting, and pre-treatment processes to effectively separate casings, current collectors, separators, and black mass, while controlling fire and explosion risks and coordinating treatment of solvents, electrolytes, and other hazardous substances.

Focusing on lithium, nickel, cobalt, manganese, and other metals in black mass, we build leaching, extraction/precipitation, purification, and crystallization hydrometallurgical units. Combined with process parameter optimization and impurity control strategies, we produce battery-grade lithium carbonate, nickel-cobalt-manganese sulfate, and other high-purity raw materials, providing stable feedstock for cathode material regeneration lines.
