EcoGraf Limited (ASX: EGR; Frankfurt: FMK) has reached a significant milestone in Australia: The company successfully secured its first national patent for its innovative HFfree® purification process after addressing two objections. The patent (Patent Number 2021261902) is retroactive to May 2021 and runs until 2041.
The process, which does not use hydrofluoric acid, is central to EcoGraf’s strategy to establish sustainable and cost-effective production of high-purity battery anode material. In addition to the patent now granted, the Australian patent series also includes a second patent family, which will protect the company’s comprehensive flowsheet technology from May 2025. Both patents form the basis for the Product Qualification Facility (“PQF”) in Australia, which is supported by the government as part of the Critical Minerals Development Program.
Wide Range of Applications and Global Patent Rights
The now secured processes cover a wide range of applications – from the production of spherical battery anode graphite and high-purity graphite products to the recycling of anode material from used lithium-ion batteries. In parallel, EcoGraf is pursuing an international protection program: Patents have already been granted in the USA, South Africa, as well as in Tanzania, Mozambique, and Namibia. Further applications are pending, among others, for the EU, South Korea, Malaysia, and Vietnam.
Cost Advantages on an Industrial Scale
The patent filing immediately follows the company’s recent announcement that process optimizations have enabled a cost reduction of approximately 25%. This makes EcoGraf one of the most cost-effective providers in the field of high-purity battery anodes. For the planned commercial purification plant on an industrial scale, a Net Present Value (NPV) of US$282 million was recently estimated.
Sustainable Supply Chain outside China
EcoGraf aims to establish an environmentally friendly and geographically diversified supply chain for battery anode material. The plan is to build purification plants in North America, Europe, and the Asia-Pacific region to meet the growing demand in key battery industries outside China. Customers will thus gain access to one of the most cost-effective and sustainable battery anode materials worldwide. The combination of cost advantages, government support, and growing customer interest could pave the way for off-take agreements and further expansion into global battery markets.
