Safely dismantling the battery cells from the battery pack
Cells are bathed in nitrogen to make them inert and eliminate risks such as combustion or other hazards.
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.
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.
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.
Selecting and optimizing the chemical precipitation agents are essential to achieving high value output composition.
High yield > 95%
Cathode - individual sulfates & hydroxides
Anode - battery grade graphite
