American Manganese bags second patent in Lithium-ion Battery Recycling


SURREY (Scrap Register): American Manganese Inc has enhanced its patent portfolio, saying it had been granted a second for its ground-breaking lithium-ion battery recycling technology.

The patent, from the relevant authority in the USA, was issued within 12 weeks from the date of filing on March 14 this year, the firm said.

The company now holds six patents, with a further seven filed for recycling around the globe, it told investors.

The firm’s technology allows for high extraction rates of cathode metals, such as lithium, cobalt, nickel, manganese, and aluminum at battery grade purity, with minimal processing.

The company says it's patent portfolio differs from other lithium-ion battery recyclers because it does not require any high heat smelting and produces a precursor cathode material for use in the manufacturing of new lithium-ion batteries.

The company said in a statement on Wednesday that the patent referred to today adds the following enhancements to the technology, which is called the RecycLiCo process:

-- Recovery of graphite and carbon from ground battery concentrates

-- Treatment of fluoride originating from electrolyte solution

-- Separation of aluminum from cathode active material
