Battery materials and technology company Talga Group (ASX:TLG) has entered a development agreement with V4Smart GmbH & Co. KG, a German battery innovator co-owned by Porsche AG and VARTA AG.
The collaboration aims to jointly develop and qualify Talga's high-performance graphite anode for next-generation fast-charging battery cells.
While non-binding, the agreement marks a significant step toward establishing a secure European supply chain, with both companies planning to move to binding offtake and volume agreements once key technical milestones are achieved.
The project is aligned with Talga's commercial ramp-up strategy and targets completion by Dec. 31, 2027, covering agreed anode specifications, qualification volumes, and indicative commercial volumes, with potential expansion into material recycling.
V4Smart, acquired by Porsche AG in March 2025, specialises in ultra-high-performance lithium-ion battery cylindrical cells manufactured in Germany.
Talga CEO Martin Phillips said the partnership highlights growing demand for sustainable, high-performance anode solutions in the fast-charging battery market and could expand Talga's customer base and production volumes at its Swedish facility.
He added that the collaboration may eventually extend beyond automotive applications to premium high-performance battery sectors.
At the time of reporting, Talga Group's share price was $0.41.
