American Manganese’s lithium-ion battery recycling technology achieves high purity

American Manganese (TSX.V: AMY) reported achieving 99.88% purity in its production of NMC cathode material using its proprietary RecycLiCo process.

Scrap NMC contains lithium-nickel-manganese-cobalt and, according to the British Columbia-based firm, its technology is capable of recycling the minerals and generating products for lithium-ion batteries.

In a press release, the company said that the high-purity recovery rates recently reported prove that it is possible to expect a sustainable supply of such metals.

“Cathode materials require extremely high purity levels and must be almost entirely free of unwanted metals in order to conform to industry specifications, which our initial results confirmed today,” Larry Reaugh, American Manganese’s CEO said in the media brief.

Besides high purity, AMY’s technology showed earlier this year that it is also able to achieve high extraction rates.

In a series of tests run by independent lab Kemetco, recovery rates were of 94% from NMC scrap and 91.4% from NCA scrap, the latter containing lithium-nickel-cobalt-aluminum.
