American Manganese begins final stages testing of NCA cathode materials at Recycling pilot plant project
VANCOUVER (Scrap Register): American Manganese Inc. has announced the beginning of Kemetco Research’s testing of NCA cathode material on Stages 3, 4, and 5 of the RecycLiCo™ Pilot Plant – a proprietary innovation of American Manganese Inc. that recycles cathode materials from lithium-ion batteries.
Stages 1 and 2 of the Pilot Plant consisted of a pre-treatment and leach on the NMC (lithium-nickel-manganese-cobalt) and NCA (lithium-nickel-cobalt-aluminum) cathode material to produce 500L of pregnant leach solution from each chemistry.
Kemetco Research Inc., the Company’s independent research contractor, first conducted tests on stages 3 and 4 using the recovered NMC pregnant leach solution and reported 99.93% purity results.
Kemetco will now conduct the same tests for the NCA cathode material to demonstrate recycling opportunities with other cathode chemistries. Once complete, the final stage of the Pilot Plant project, stage 5, will include the recovery of battery grade lithium carbonate as well as the recycling of process reagents and water. Stage 5 will also incorporate a new patent application that improves processing and recovery capabilities.
“There are many lithium-ion battery cathode chemistries used in a variety of applications from portable electronics to electric vehicles. The NCA and NMC cathodes are popularly used in electric vehicles, such as Tesla, Nissan, BMW, and Volkswagen battery packs,” said Larry Reaugh, President and CEO of American Manganese.
“The Pilot Plant project has attracted significant industry attention and the Company plans to extend testing and provide proof of concept for third-party materials, which consist of NMC and NCA cathode materials,” he said.
