AnteoTech and Xerabrid seal deal to advance next-gen battery separators
AnteoTech has formalised a strategic alliance with South Korea’s Xerabrid to co-develop and commercialise a breakthrough battery separator combining their proprietary technologies, targeting high-performance applications in eVTOL, EVs, and consumer electronics.
- Strategic Collaboration and Sales Agreement executed with Xerabrid
- Combined Anteo S™ and Ceramic Coated Separator achieves zero shrinkage at 150°C
- Seven international manufacturers requested samples, including 1,000-metre roll
- Focus on sample production, customer testing, and commercial manufacturing scale-up
- Targets defence, consumer electronics, EV, and supercapacitor markets
Strategic Alliance Targets Safer, Thinner Battery Separators
AnteoTech Ltd (ASX:ADO) has taken a significant step in commercialising its Anteo S™ battery separator technology by signing a Strategic Collaboration and Sales Agreement (SCSA) with South Korean separator specialist Xerabrid Corporation. This formalises a partnership to jointly develop, market, manufacture, and sell a combined high-performance separator product that integrates AnteoTech’s patented cross-linking chemistry with Xerabrid’s Ceramic Coated Separator (CCS) technology.
The combined product has demonstrated exceptional thermal stability and mechanical strength, with testing showing zero separator shrinkage after exposure to 150°C for one hour. This is a critical improvement for battery safety and performance, especially in demanding applications such as electric vertical take-off and landing (eVTOL) aircraft, drones, electric vehicles (EVs), and consumer electronics.
Strong Early Customer Engagement Signals Market Interest
Since the initial binding term sheet in May 2026, AnteoTech and Xerabrid have engaged seven international energy storage manufacturers and OEMs. All have requested samples of the combined separator, with one customer seeking a 1,000-metre roll for prototyping and pre-commercial trials. These samples are scheduled for delivery by October 2026, marking a crucial phase of customer testing and validation.
Potential customers are primarily focused on reducing separator thickness to increase battery energy density without compromising safety or thermal stability. The combined Anteo S™ and CCS product addresses these demands by enabling thinner ceramic coatings; up to 65% thinner than industry standards; while enhancing puncture resistance and tensile strength.
Commercial Manufacturing and Market Expansion Plans
The SCSA outlines flexible manufacturing models, including in-house production, toll manufacturing, and licensing, with commercial terms kept confidential. Xerabrid plans to scale up to commercial manufacturing capacity in calendar year 2027, supported by AnteoTech’s supply of Anteo S™ material for market seeding and sample production.
AnteoTech’s Managing Director Merrill Gray highlighted the strategic importance of the collaboration, noting the combined product’s potential to accelerate market entry across battery energy storage systems (BESS), EVs, consumer electronics, and defence sectors. The partnership also positions AnteoTech closer to end customers by delivering a fully formulated product rather than Anteo S™ as a standalone component.
Global Market Reach and Future Development
The initial commercial focus targets key markets including the USA, South Korea, India, and Japan, with China representing over half of global separator manufacturing capacity. AnteoTech is exploring additional sales channels to accelerate market penetration and plans to showcase the combined product at the US Battery Show in Detroit in October 2026.
Xerabrid, founded in 2018 and led by CEO Dr Chris Song, brings deep expertise in ceramic coating technologies and separator manufacturing. Their CCS technology is designed to meet the stringent safety and performance requirements of next-generation lithium-ion and lithium-sulphur batteries.
The collaboration also aims to continue product improvement and develop next-generation separator solutions based on customer feedback, underpinning AnteoTech’s ambition to expand its footprint in the growing battery materials sector.
Bottom Line?
AnteoTech’s alliance with Xerabrid advances its Anteo S™ technology from lab innovation to market-ready product, with customer validation and manufacturing scale-up now in focus.
Questions in the middle?
- Will customer testing translate into commercial sales and broader adoption of the combined separator?
- How will Xerabrid’s manufacturing scale-up in 2027 impact AnteoTech’s revenue and market penetration?
- What further innovations might emerge from the partnership to address evolving battery safety and performance needs?
