AnteoTech Advances Anteo C Primer Coating to Manufacturing Scale

Manufacturing-Scale Milestone for Anteo C Primer Coating

AnteoTech Ltd (ASX:ADO) has taken a significant step forward in commercialising its Advanced Battery Technology with the launch of Anteo C, a new cross-linker additive designed for primer coatings on copper and aluminium foils used in lithium-ion batteries (LiBs). Following successful laboratory and pilot-scale trials, the company has shipped a 20-litre manufacturing-scale sample to a South Korean contract coating company for evaluation.

This progression from lab to manufacturing scale is critical in the battery materials industry, where primer coatings play a vital role in enhancing electrode performance. Anteo C is applied as a thin functional layer between the current collector foils and active material coatings, improving adhesion, electrical contact, and process robustness.

Enabling Water-Based, PFAS-Free Battery Manufacturing

One of the standout features of Anteo C is its water-based, PFAS-free formulation. Traditional primer coatings often rely on fluoropolymers like PVDF and PTFE, which contain per- and polyfluoroalkyl substances (PFAS); chemicals increasingly targeted by regulatory restrictions due to environmental concerns. Anteo C’s PFAS-free chemistry integrates seamlessly into existing aqueous primer coating processes, offering manufacturers a sustainable alternative without compromising performance.

Anteo C stabilises the primer coating by cross-linking water-soluble binders, preventing dissolution during the application of water-based anode or cathode active material slurries. This addresses a key challenge in transitioning to lower-cost, environmentally friendly water-based binders, which can otherwise compromise electrode integrity and battery performance.

Expanding Market Reach Across Key Asian Battery Hubs

AnteoTech is actively engaging with customers beyond South Korea, including a large potential client in India, and is exploring commercial pathways into China, the world’s largest lithium-ion battery manufacturing centre. The company’s South Korean distributor, Kangshin Industrial, is supporting customer identification and engagement efforts locally, while AnteoTech’s Advanced Battery Technology team recently showcased its products at The Battery + Charging Show in South Korea alongside collaborator Xerabrid.

The global market opportunity for aluminium and copper foil primer coatings in lithium-ion batteries is projected to reach US$21 billion annually by 2032, driven by trends such as the adoption of silicon-based anodes and the shift to water-based Lithium Iron Phosphate (LFP) cathode processing. Anteo C’s applicability to both anode and cathode current collectors significantly broadens AnteoTech’s addressable market.

Product Suite Diversification and Growth Prospects

Anteo C is the second new product launched by AnteoTech’s Advanced Battery Technology division in 2026, complementing earlier releases such as Anteo S™ for separator technologies and the Ultranode™ high silicon anode formulations. Together, these products create multiple commercial opportunities across the lithium-ion battery value chain, positioning AnteoTech for growth in FY2027.

While the company has not disclosed specific financial terms or timelines for commercial adoption, the successful scale-up and customer engagement signal positive momentum. The focus on PFAS-free, water-based chemistries aligns AnteoTech with global regulatory trends and sustainability demands, which may prove increasingly important as battery manufacturers seek to reduce environmental impact.
