Anteotech Ltd Ships 20L Anteo C Sample for South Korean Battery Trials
AnteoTech ships 20L Anteo C sample to South Korea in fresh battery tech milestone
AnteoTech (ASX: ADO) has launched a new Anteo C primer coating product and shipped a 20 Litre (L) sample to a South Korean manufacturer for customer product integration scale trials.
The development marks a fresh commercialisation milestone for the company’s Advanced Battery Technology (ABT) business. Anteo C is the second new ABT product introduced in 2026, following the earlier release of Anteo S™ for separator technologies.
The product has progressed from laboratory-scale evaluation to manufacturing-scale process trials. According to the company, Anteo C can be utilised in primer coatings on both copper foil (anode) and aluminium foil (cathode) current collectors, significantly expanding the company’s addressable market into a sector estimated to reach ~US$21 billion in annual revenues by 2032.

From 100mL lab test to 20L scale trial, the commercialisation pathway
The progression of Anteo C reflects a series of customer-validated steps that have steadily moved the product closer to potential commercial adoption.
The milestone sequence unfolded as follows:
-
An initial 100 mL Anteo C sample was tested at lab-scale by a contract coating company in South Korea, returning positive results.
-
The positive testing led to the supply of a 5 L sample for pilot-scale Roll-to-Roll (R2R) coating trials.
-
The pilot trials were successfully completed, with the coated material subsequently provided to an end customer for evaluation.
-
The contract coating company then requested a 20 L sample, now shipped, for evaluation as a primer coating on aluminium current collectors for water-based Lithium Iron Phosphate (LFP) cathode production.
Each step represents a customer-validated progression toward commercial adoption, helping to reduce technical risk as the product moves through the qualification process.
The company has also identified additional Anteo C customer opportunities globally, with commercial engagement activities now underway.
What Anteo C actually does (and why primer coatings matter)
The role of primer coatings in lithium-ion batteries
Primer coatings in Lithium ion Batteries (LiBs) are very thin functional layers applied to the metal foil current collectors, copper foil on the anode and aluminium foil on the cathode. They consist of a thin layer of conductive carbons and binders that hold the structure together and bind it to the foil surface.
According to AnteoTech, primer coatings are designed to:
-
Increase adhesion between the active material and the current collector
-
Reduce electrical contact resistance
-
Protect against corrosion, allowing, for example, LFP cathodes to be coated using water-based processing
The problem Anteo C solves
A key challenge facing the industry is the transition to lower-cost, water-based binders. While these binders offer cost and environmental advantages, they can readily dissolve when water-based slurries are applied during electrode manufacturing, compromising the integrity of the primer coating and reducing battery performance.
Anteo C is a cross-linker performance additive that cross-links the binder’s molecular structure, stabilising the primer coating and preventing dissolution during manufacturing.
The product also carries an environmental angle. Primer coatings often contain PFAS (per- and polyfluoroalkyl substances, commonly referred to as “forever chemicals”), particularly fluoropolymers such as PVDF and PTFE. Anteo C is a water-based, PFAS-free product that integrates into existing aqueous primer coating manufacturing processes.
With many countries seeking to restrict or ban the importation of batteries containing PFAS, the company states that its PFAS-free LiB products can support growing environmental needs while delivering battery performance outcomes for manufacturers. This positions Anteo C as an option for manufacturers seeking to manage costs and environmental requirements simultaneously.
A US$21 billion addressable market opportunity
Anteo C can be used in primer coatings on both copper foil (anode) and aluminium foil (cathode) current collectors, significantly expanding the company’s addressable market.
| Application | Driver | Why it matters for Anteo C |
|---|---|---|
| Copper foil (anode) | Rising silicon-anode adoption | Primer improves interfacial adhesion |
| Aluminium foil (cathode) | Shift to water-based LFP processing | Provides corrosion protection and lower resistance |
| Both | PFAS restrictions globally | PFAS-free alternative to PVDF |
Combined, the global LiB copper and aluminium foil current collector markets are estimated to reach ~US$21 billion in annual revenues by 2032, according to figures cited by the company from multiple industry reports.
Growth in primer-coated copper foil is being driven by increasing adoption of silicon-based anodes, where primer coatings improve interfacial adhesion. On the cathode side, manufacturers, particularly in Asia, are increasingly transitioning to water-based LFP processing, replacing traditional solvent-based manufacturing using N-methyl-2-pyrrolidone (NMP). These structural industry trends are expected to drive increased adoption of primer-coated current collectors over the coming years.
Building momentum across global markets
AnteoTech is pursuing engagement across several international markets as it seeks to broaden the commercial footprint of its ABT products.
-
South Korea: Distributor Kangshin Industrial Co. Ltd is supporting the identification of and engagement with additional potential Anteo C customers. One of the ABT team attended The Battery + Charging Show alongside Anteo S™ collaborator Xerabrid and visited potential customers.
-
India: The team has expanded its outreach to a large potential customer and received a positive response.
-
China: As the world’s largest LiB manufacturing centre, China offers medium and long-term sales volume potential. AnteoTech is currently assessing a range of commercial pathways and partnership opportunities as part of investigating future market entry potential.
Merrill Gray, Managing Director & CEO
“This is a very positive development within a relatively short timeframe of entering the South Korean market, and we look forward to continued momentum building across this and all our products in this market.”

What this means for AnteoTech investors
The launch of two new ABT products in 2026, Anteo C and Anteo S™, expands AnteoTech’s addressable market across the LiB value chain, extending beyond its high-silicon Ultranode™ and Anteo X™ offerings.
According to the company, its versatile chemical platform underlies these multiple commercial opportunities. Anteo S™ is currently being tested at pilot-scale by customers in South-East Asia and the USA, adding to the broader momentum narrative.
The Ultranode 95 validation milestone, completed at the Battery Innovation Centre in Indiana, confirmed more than 300 cycles at 70% capacity retention in commercial 5 Ah pouch format cells, positioning the high-silicon anode technology as a parallel commercial pathway alongside the primer coating products.
Management has framed the product suite as providing a platform for growth in FY2027. Importantly for investors, the Anteo C engagements remain at the evaluation stage, with no commercial sales disclosed at this point. The milestone reflects technical progression and market validation rather than committed revenue.
For investors exploring the full scope of AnteoTech’s ABT and life sciences pipeline beyond primer coatings, our detailed coverage of AnteoTech’s broader commercial strategy outlines the Ultranode 95 JDA negotiations, the company’s $12.8 million pro-forma cash position, and its combined addressable markets exceeding US$60 billion annually.
