EcoGraf has received a patent for its purification technology that relates to the manufacture of battery anode material and high purity graphite products, together with the recycling of lithium-ion battery anodes.
The Australian Government Patent Office, through IP Australia, has confirmed acceptance of the company’s patent application for EcoGraf’s HFfree purification technology.
The patent comes after the Examiner at the International Preliminary Examining Authority found all 25 of the patent claims were novel and inventive.
The purification technology was first developed by EcoGraf in Australia and has been refined through extensive testing and analysis conducted in Europe and Asia.
The process produces battery anode material using natural flake graphite, and has been demonstrated using a range of different graphite feedstocks produced in Asia, Africa and South America.
The company’s Battery Anode Material Facility in Western Australia will now export battery anode material products to anode, lithium-ion battery and electric vehicle markets in Asia, Europe and North America.
Recycling battery scrap
In August 2020, EcoGraf announced its proprietary purification process had been successfully applied to recycling battery materials from ‘production scrap’ and ‘black mass’.
In testing undertaken in collaboration with potential customers, the firm’s proprietary purification process returned results of 98.6-100% carbon from production scrap and 98-99.6% from black mass.
