AnteoTech Launches Anteo C Performance-Enhancing Primer Additive for Lithium-Ion Batteries

AnteoTech (ASX: ADO) has expanded its advanced battery technology (ABT) portfolio with the launch of performance-enhancing additive Anteo C for use in primer coatings on copper foil (anode) and aluminium foil (cathode) current collectors in lithium-ion batteries.

The launch follows initial laboratory-scale testing of a 100-millilitre sample by a contract coating company in South Korea and led to the supply of a five-litre sample for pilot-scale roll-to-roll coating trials.

AnteoTech has since progressed to manufacturing-scale process trials with a 20L sample shipped to the same contract coating company for evaluation as a primer on aluminium current collectors for water-based lithium-iron phosphate cathode production.

AnteoTech’s South Korean distributor Kangshin Industrial Co is working to identify and engage with additional Anteo C customers in the region while the company’s ABT team has expanded its outreach to a large potential customer base in India.

Water-Based Product

Anteo C is a water-based, PFAS (per- and polyfluoroalkyl substance)-free product that readily integrates into existing aqueous primer coating manufacturing processes while delivering superior battery performance outcomes for LiB manufacturers.

It enables the use of cost-effective and higher-performance aqueous primer coating binders by cross-linking the binder’s molecular structure, which stabilises the primer coating and prevents dissolution during the anode or cathode manufacturing process.

The process is designed to improve the mechanical and electrochemical properties of primer coatings and, ultimately, lithium-ion battery electrode performance.

Anteo C complements Anteo S, which the company released earlier this year for separator technologies and is currently being tested at pilot-scale by customers in south-east Asia and the US.

New Markets and Applications

Managing director Merrill Gray said the company was keen to hit the market with both products.

“AnteoTech’s versatile chemical platform, combined with our ABT team’s in-depth understanding of the chemicals and materials that make up lithium-ion batteries and how they interact at a molecular level, has led to the development of two new products this year, […] opening up new markets and applications for the company,” she said.

“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 all our products in this market.”

“We are actively engaging with potential customers in other key markets directly—the product suite developed by the ABT team provides an exciting platform for growth in FY27.”
