Process Produced 100% Match to Commercial Grade Material
Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc. (“American Manganese” or “AMI” or the “Company”), (TSX.V: AMY; Pink Sheets: AMYZF; Frankfurt: 2AM), is pleased to announce that Kemetco Research Inc. (“Kemetco”) has successfully produced Li:Ni:Mn:Co (NMC) cathode material and working coin cell rechargeable NMC batteries using recycled lithium, nickel, manganese, and cobalt from AMI’s patent pending lithium ion battery cathode material recycling process.
Preliminary battery cycling test of the NMC battery has demonstrated that it reached the targeted battery capacity, which further proves American Manganese’s patent pending battery recycling process can recycle and refabricate the NMC material to make new NMC batteries.
“Based on these preliminary results,” said Norm Chow, President of Kemetco, “it can be speculated that the American Manganese upcycling technology represents the world’s first NMC Battery produced from AMI’s closed loop recycling process.”
“These results continue to validate the AMI process,” said Mr. Reaugh. “With this phase of test work, we’ve taken very complex lithium-ion battery cathode material from the recovered components through the reconstitution of the NMC cathode materials to produce working chargeable cells.”
Battery Fabrication and Assembly
Recycled NMC was generated by precipitating the metal components from a leached solution of commercially available feedstock. XRD (X-ray diffraction) of the reconstituted NMC material has characterized the material as having a perfect ratio of Li:Ni:Mn:Co = 1.06:0.33:0.33:0.33 — a 100% match to the commercial battery grade of NMC.
This cathode material mixture was subsequently coated onto aluminum foil and dried for 2 hours at 120°C in a vacuum oven to form the lithium-ion battery cathode.
The button cell batteries were assembled as follows: top cell case, cathode, separator, anode, spacer, ring-shaped spring, and bottom cell case. The anode was made from purchased graphite. The ring-shaped spring was placed between the negative casing and the spacer to ensure adequate pressure was applied to the cell components. Both the spring and the spacer are made from stainless steel. A thin layer of polyolefin was used as the separator.
