Next-Generation Battery Recycling Systems
SPT Recycling integrates two advanced processes into one streamlined circular-materials system:
- Roasting-Free Dry Dismantling – mechanical battery disassembly under inert atmosphere, with no pyrolysis, no wastewater, and ultra-low emissions.
- Solvent-Free Hydrometallurgy – green leaching and purification using an organic-solvent-free method that delivers exceptional recovery rates.
Together, these processes produce high-purity black mass, recycled graphite, copper, aluminum, steel, and battery-grade lithium and metal salts – ready for reuse in next-generation battery manufacturing.
Recycling Recovery Output
Dry Dismantling – Annual Output
From 10,000 tons of battery packs, our dry process recovers key materials at up to 99% efficiency:
- Black Powder: 3,600 t (99%)
- Copper: 570 t (95%)
- Aluminum: 360 t (95%)
- Steel Casings: 1,290 t (99%)
- Plastics & Separators: 720 t (99%)
- Electrolyte: 610 t (95%)
Wet Process Output – Annual Yield
From 8,000 tons of black powder, our solvent-free hydrometallurgical process produces battery-grade materials with high recovery efficiency:
- Nickel–Cobalt–Manganese Sulfate: 12,000 t at 99%, convertible to NCM ternary precursors
- NCM Ternary Precursor: 3,870 t at 99%, metal totals preserved
- Lithium Carbonate (Battery Grade): 1,450 t at 95%, convertible to LiOH
- Lithium Hydroxide (Battery Grade): 1,625 t at 95%, lithium total constant
- Sodium Sulfate (Industrial Grade): 11,000 t at 98%
- Recycled Graphite Powder: 3,136 t at 98%, suitable for battery applications
Closed-Loop Recycling System
Dry + Wet Processes Working as One Efficient Loop
Our short-process technology links dry dismantling and solvent-free hydrometallurgy into a single, fully integrated recycling system. Each stage feeds the next, ensuring maximum material recovery with minimal loss.
Dry Process Creates High-Quality Feedstock
The roasting-free dismantling line separates batteries into clean fractions – black powder, metals, plastics, and electrolyte – without high temperatures or wastewater.
- Black mass is recovered at 99% and delivered directly to the wet process.
- Electrolyte is captured and reused.
- Metals and casings are recovered as clean by-products.
Wet Process Upgrades Materials to Battery-Grade
The extraction-free hydrometallurgical stage converts black mass into:
- NCM sulfates & ternary precursors (99% recovery)
- Battery-grade lithium carbonate or hydroxide (95% recovery)
- Recycled graphite powder (98% recovery)
All outputs meet industrial and battery manufacturing specifications.
Closed-Loop Efficiency
Together, both processes form a continuous circular system:
- No pyrolysis, no combustion emissions
- No organic solvents
- Minimal solid waste
- Near-zero discharge
- Full recovery of valuable metals, lithium, graphite, and electrolyte
This closed-loop design delivers maximum resource efficiency with minimal environmental impact — setting a new standard for clean lithium battery recycling.
