EcoGraf HFfree® India Patent Granted

EcoGraf HFfree^® India Patent Granted

Strengthening EcoGraf’s Position in Emerging Ex-China Battery Materials Supply Chains

EcoGraf Limited (“EcoGraf” or “the Company”) (ASX: EGR; FSE: FMK) is pleased to announce that The Patent Office, Government of India has granted EcoGraf an India patent for its first EcoGraf HFfree® purification patent (“Patent Family 1”).  The patent numbered 587710 has a term of 20 years expiring on 14 May 2041 (“Patent”). 

The India patent covers use of the Company’s EcoGraf HFfree® purification technology across a range of applications relating to the manufacture of battery anode material, high purity graphite products and the recycling of lithium-ion battery anodes.

Protection of intellectual property rights is a key aspect of EcoGraf’s vertically integrated battery anode materials business, which is underpinned by the use of low-cost and environmentally sustainable process technology for the planned production of high purity natural flake and spherical graphite in Tanzania and the establishment of EcoGraf HFfree® purification facilities in key global battery markets.

Patent applications have separately been made by EcoGraf as shown in Table 1 below in other planned processing locations, including the EU, Korea and Malaysia. The Company is pleased to note that Patents for the 1st Patent Family have also been granted for Australia, US, South Africa and Tanzania, Mozambique and Namibia.

In addition to the above, the Company has also recently submitted its third patent application to provide further coverage and protection based on the latest developments.

The Company notes that recent Chinese restrictions on dual‑use materials have intensified global interest in developing diversified and resilient critical raw material supply chains. This shift supports the Company’s strategy to establish purification facilities in North America, Europe and the Asia‑Pacific region¹, enabling localised supply outside China and positioning the Company to meet the growing demand for alternative, low‑cost and sustainable battery anode materials.

About EcoGraf

EcoGraf is building a vertically integrated battery anode materials business to produce high purity graphite products for the lithium-ion battery and advanced manufacturing markets. Over US$30 million has been invested to date to create a highly attractive graphite business which includes:

• Epanko Graphite Mine in Tanzania;

• Mechanical Shaping Facility in Tanzania; 

• EcoGraf HFfree^® Purification Facilities located in close proximity to the electric vehicle, battery and anode manufacturers; and

• EcoGraf HFfree^® Purification technology to support battery anode recycling.   

In Tanzania, the Company is developing the TanzGraphite natural flake graphite business, commencing with the Epanko Graphite Project, to provide a long-term, scalable supply of feedstock for EcoGraf^® battery anode material processing facilities, together with high quality large flake graphite products for specialised industrial applications.

In addition, the Company is undertaking planning for its Mechanical Shaping Facility in Tanzania, which will process natural flake graphite into spherical graphite (SpG). This mechanical micronising and spheronising is the first step in the conversion of high-quality flake graphite concentrate into battery grade anode material used in the production of lithium-ion batteries.

Using its environmentally superior EcoGraf HFfree^® purification technology, the Company will upgrade the SPG to produce 99.95%C high performance battery anode material to supply electric vehicle, battery and anode manufacturers in Asia, Europe and North America.

Battery recycling is critical to improving supply chain sustainability and the Company’s successful application of the EcoGraf HFfree^®   purification process to recycle battery anode material provides it with a unique ability to support customers to reduce CO₂ emissions and lower battery costs.
