Another Australian Patent to be Granted!
Australian graphite company EcoGraf (WKN A2PW0M / ASX EGR) reports further progress in the development of its vertically integrated business for the production of battery anode materials (BAM). On one hand, a breakthrough was achieved in the development of a new and more environmentally friendly battery anode material, and on the other hand, according to the company, the second HFfree® patent application (HFfree = free of hydrofluoric acid) for graphite purification will now be granted!
EcoGraf can now report that the latest results from the company’s product qualification facility show that it meets the highest chemical specifications of customers for spherical graphite (SPG), while maintaining the important physical specification. According to EcoGraf, this represents a technical breakthrough.
The company had recently reported the successful commissioning of its PQF and has since conducted numerous operational campaigns there. EcoGraf has thus demonstrated that the hydrofluoric acid-free purification technology achieves an “extremely” high purification level of 99.99% carbon with only minor impurities, while maintaining operating conditions that meet the highest customer requirements for purified, spherical graphite!
Patent Progress in Australia
Another positive development is that IP Australia (the Australian Patent Office) has accepted the second application for EcoGraf’s HFfree® purification method and it will now be granted. The second patent application was filed to ensure broader protection for the company’s HFfree® purification technology.
EcoGraf’s second Australian patent covers the additional use of EcoGraf HFfree® purification technology in a range of applications related to the production of battery anode material and high-purity graphite products. It also extends to the recycling of battery anodes from lithium-ion batteries.
Discussions with Potential Customers Continue
In parallel with the technical work, EcoGraf continues discussions with a number of original equipment manufacturers (OEMs) from the automotive industry, battery producers, and potential supply chain customers. Currently, the company is also working on qualifying product samples for more than six major battery companies in Europe, Asia, and North America.
The company expects to advance offtake and cooperation agreements regarding the HFfree® purification technology with some of these leading industry groups.
The Strategy
EcoGraf plans to produce unpurified, spherical graphite in Tanzania using favorable, environmentally friendly hydropower. The goal is also to build graphite purification plants in major battery manufacturing centers in Europe, North America, and Asia using the HFfree® technology, which is also patented in the USA.
EcoGraf is currently evaluating a number of potential development sites, as it anticipates that from early 2027, the use of battery anode material manufactured outside of China will increase significantly due to increasing relevant legislation in the EU and USA.
The plan is to source the graphite for these planned facilities from EcoGraf’s Epanko project in Tanzania, which EcoGraf has already developed to the financing phase while maintaining the highest standards. The company has now commissioned KfW IPEX-Bank to arrange a senior credit facility (UFK tranche) of up to $105 million to finance the construction of a mine at Epanko. Recently, the company completed a substantial environmental and social planning program to support the financing and further development of Epanko.
EcoGraf is confident that starting with the high-quality natural flake graphite from Epanko, the cost-effective and green production of spherical graphite in Tanzania, and the HFfree technology, it can offer potential customers significant cost advantages with environmentally friendly production.
