In the complex landscape of the global battery industry, the gap between “innovative material” and “market-ready product” is often the hardest to bridge. Within the STREAMS project, we are seeing this gap closed through a remarkable transatlantic partnership between the Austrian Institute of Technology and American Energy Technologies Co. (AETC).
The origin of a success story
The partnership traces its roots back to the very beginning of the STREAMS project. What started as a shared vision during the proposal phase quickly transitioned into a commercial reality. Following the project’s award, AIT and AETC initiated a series of commercial Science & Technology projects, now in their third successful iteration, focused on the testing and qualification of AETC’s specialised graphite in large-format lithium-ion cells.
A technological leap: The 100% yield goal
One of the most significant outcomes of this collaboration involves AETC’s “Inverted Flow Sheet” technology. Traditionally, graphite processing, primarily practiced in Southeast Asia, results in a yield of only 35% to 50%, with significant waste.
AETC’s innovative approach produces both spherical graphite for anodes and non-spherical additives for cathodes in a single production run. The result? A yield approaching 100%. This efficiency is a game-changer; it allows for high-quality graphite production on US and European soil at costs that are competitive with global market offerings, while significantly reducing the environmental footprint and supply chain vulnerabilities.
To move from theory to application, the collaboration utilised AIT’s world-class battery manufacturing facilities in Austria. A dedicated team of scientists scaled the formulations from bench-scale to a research pilot line, producing 5Ah+ pouch cells. These cells are representative of the building blocks used in electric vehicle modules and large-scale energy storage systems.
Crucially, the partnership also qualified the performance of these materials in aqueous binder systems.
By proving that these materials perform exceptionally well without the need for toxic organic solvents, the partners are aligning industrial growth with the highest environmental and health standards.
A roadmap for the future
For STREAMS, this partnership is another great validation of our Exploitation Strategy. It proves that by fostering the right network, we can trigger commercial success stories that increase our independence from geopolitical fluctuations and build a more transparent, predictable supply chain.
As STREAMS Project Coordinator, Damian Cupid, noted: “Qualifying and testing innovative materials developed by industrial partners is a fascinating field. Our work with AETC shows that we can integrate carbon-based materials from non-conventional sources into reliable supply networks, increasing our autonomy.”
