99.977% Purity from Recycled Lithium-ion Battery Material

American Manganese Inc has reported on the successful recovery of high purity (99.977%) nickel-cobalt hydroxide from the NCA cathode scrap material received from the tier-one lithium-ion battery company referenced as Company A. These results follow the previously announced 99.98% purity results from recycled NCA cathode scrap material received from Company B. Laboratory studies were conducted by the Company's independent contractor, Kemetco Research. For more information see the IDTechEx report on Second-life Electric Vehicle Batteries 2020-2030.
"The almost identical purity test results are an indication that the RecycLiCo™ patented processes can remain consistent and repeatable on cathode scrap material sourced from different companies," said Norm Chow, President of Kemetco Research.
The next steps involve shipment of high purity recycled material back to the tier-one companies for analysis and confidential technical discussion regarding the recycling process. American Manganese's objective is to collaborate efforts with the tier-one companies to seamlessly integrate recycled material into the re-manufacturing of battery cathodes.
American Manganese believes the demand for recycling is immediate and lithium-ion battery manufacturers could benefit from integrating recycled cathode material in their manufacturing process because it would create use for their production scrap waste, reduce reliance for mined raw materials, and improve battery production costs. For reference, Benchmark Minerals Intelligence is tracking 102 battery Megafactories with the potential manufacturing capacity to provide battery power for 36 million electric vehicles. Also, the price of cobalt hydroxide, referenced in the following article, is calculated at a 19% premium over the value of cobalt metal.
"Our RecycLiCo™ patented process offers a robust and closed-circuit hydrometallurgical solution that does not use a conventional high-heat smelting process known as pyrometallurgy," said Larry Reaugh, President and CEO of American Manganese. "For example, the cost of the reagent consumption in our process is estimated to be less than 10% of the recoverable value in the cathode material."
