Recycling and minerals firm American Manganese announced on May 29 it had published its US patent application for a system that can recycle lithium ion cathode materials.

The product application discusses the company’s hydrometallurgical process for the recycling and recovery of cathode materials such as lithium, cobalt, nickel, manganese and aluminium from lithium ion batteries.

The publication is available for viewing and downloading on the World Intellectual Patent Organization’s website under publication no. WO2018/089595 and titled:  Process of Cobaltous Sulphate/Dith-ionate Liquors Derived from Cobalt Resource.

Larry Reaugh, CEO of the company said: “Publication of the patent process takes us away from the area of a black box technology and now discloses the underlying process, which we believe will assist the company in moving forward with potential partnerships.”

The ability to recover cobalt will cause many within the industry to sit up and take notice.

Last summer ESJ was investigating how demand outstripping supply of the material by 2020 as the manufacture of lithium ion batteries is ramped up to meet demand for electric vehicle and energy storage system battery packs. Read the full story here:
