Plant Design & Capabilities

FEEDSTOCK

FLEXIBLE

  • Cell agnostic

  • Form factor agnostic

  • Chemistry agnostic

MODULAR

CAPACITY

  • Expandable capacity (100-10,000 tons)

  • Geographically mobile

  • Minimal footprint

EFFICIENT

PROCESS

  • Low capex, high yield

  • Automated flow

  • Zero waste process

  • Minimal GHG emissions

Our Process

Automated process flow with proprietary algorithms

1

Cell isolation

Safely dismantling the battery cells from the battery pack

2

Pretreatment

Cells are bathed in nitrogen to make them inert and eliminate risks such as combustion or other hazards.

3

Mechanical Separation

Shredding of cells to expose the electrode material.  Electrode material is separated from the steel, plastics & copper & aluminum foil.  Our 2 stage process reduces the material fragments to < 2mm. 

1

Because the cathode & anode materials are attached to current collector plates (Cu & Al foil) by using PVDF binders, organic solvents are required to dissolve the binders to separate electrode materials from the foils.

4

Dissolution

5

Leaching

Critical step in the in our process whereby acids are used to dissolve the valuable metals into solution. What is difficult at this stage is to maximize leaching process through environmentally approved acids. 

6

Precipitation

Selecting and optimizing the chemical precipitation agents are essential to achieving high value output composition.

Our Output

  • High yield > 95%

  • Cathode - individual sulfates & hydroxides

  • Anode - battery grade graphite
