Critical minerals company American Manganese (AMY) has secured a Japanese patent for its closed-loop lithium-ion battery recycling process.
The company’s RecycLiCo process was issued Patent No. 6906060 by the Japanese Patent Office.
The Japanese patent joins already issued patents in the US and South Korea (Patent No. 10-2246670). The Company has also filed National Phase Patent Applications for China, Europe, Australia, India, and Canada.
The patent provides coverage for AMY’s closed-loop method for achieving up to 100% extraction of cobalt, nickel, manganese, aluminium, and lithium from the treatment of cathode chemistries such as lithium-cobalt oxide (LCO), lithium-nickel-manganese-cobalt oxide (NMC), and lithium-nickel-cobalt-aluminium oxide (NCA).
Compared to traditional hydrometallurgical recycling processes, the company says its process offers advantages such as faster reaction rates, lower consumption of acids, improved water balance, and higher leaching efficiency.
Larry Reaugh, president and CEO of American Manganese, said: “As we move towards our goal of commercialisation, we are reminded by the foundation of patents that supported our growth in battery recycling and we are honoured to be issued another patent by a country that is one of the world leaders in battery innovation.
“Innovation is at the core of our company and as a pioneer in battery recycling we continue to monitor new lithium-ion battery technologies and opportunities.”
