Highlights

  • Cadoux's premiumHPA high purity alumina product has successfully completed a comprehensive 7-step qualification process within the EU-funded SAFELOOP Gen3 Li-Ion EV battery development program after 24 months of testing.
  • The qualification validates premiumHPA's performance as a ceramic coating material for battery separators, demonstrating enhanced heat resistance and reduced thermal runaway risk under extreme operating conditions.
  • CCM shares were trading at AUD 0.033 on 28 May 2026, with the qualification milestone representing a potential pathway to binding offtake arrangements and a transition from technical development to commercial Supply discussions.

 

Cadoux Limited (ASX: CCM) shares were trading at AUD 0.033 on 28 May 2026, unchanged on the day. At this price level, the Market Capitalisation of Cadoux reflects the pre-Revenue, development-stage nature of the company — yet the qualification milestone announced on 28 May 2026 represents a material de-risking event that separates Cadoux from the broader peer group of HPA developers. The qualification is the kind of inflection point that typically precedes commercial conversations with Downstream manufacturers, and its significance to the company's development pathway extends well beyond the immediate share price reaction.

The Qualification: What It Is and Why It Matters

SAFELOOP is a collaborative Horizon Europe project involving 15 entities across 11 countries, focused on the development of a safe, sustainable, and high-performance Lithium-Ion Battery suitable for gigafactory-scale production. The program targets a Gen3 Li-Ion battery incorporating recycled content, with Cadoux serving as the exclusive high purity alumina supplier. After 24 months of extensive testing — covering electrochemical properties, thermal stability, lifecycle performance, and safety under demanding and extreme conditions — Cadoux's premiumHPA has successfully completed all seven stages of the qualification process and achieved Approved Vendor Status.

High purity alumina plays a critical role in Li-Ion battery architecture primarily as a ceramic coating material for battery separators. The ultra-high purity and controlled particle morphology of premiumHPA enhanced separator heat resistance, reduced shrinkage at elevated temperatures, and improved overall cell safety by minimising the risk of thermal runaway — a critical performance criterion for automotive-grade battery applications. The qualification process included initial technical engagement, sample supply and specification review, separator and electrode coating formulation testing, coin cell and pouch battery testing, pilot scale qualification, extended reliability and abuse testing, and commercial qualification.

The Commercial Significance of HPA Qualification

In the HPA sector, qualification is widely regarded as one of the most difficult and time-consuming barriers to commercial entry. The ultra-high purity requirements — typically 4N (99.99%) or higher — combined with consistency demands and application-specific performance testing mean that customers conduct extensive evaluation before approving a new supplier. Trace impurities can materially impact battery safety, semiconductor reliability, and sapphire quality, making the qualification standard a genuine technical hurdle rather than a routine procurement step.

Achieving qualification materially reduces several key project risks simultaneously: technical risk (the product demonstrably meets specification), commercial risk (a qualified customer has accepted it for use), scale-up risk (the process has demonstrated repeatability and consistency), and market acceptance risk (the product has been validated in a real-world advanced application). For Cadoux, the transition to Approved Vendor Status within a Horizon Europe consortium positions the company as a credible participant in commercial supply discussions with other downstream customers, and potentially accelerates access to project financing and strategic partnerships.

Cadoux's Broader HPA Development Pathway

Cadoux's development strategy is structured around a staged production build-out: a 1,000-tonne per annum small-scale production Facility in Western Australia, followed by a 10,000-tonne per annum full-scale commercial plant. The company's proprietary process flowsheet has been demonstrated through a pilot plant and market studies, and has received backing from both the Western Australian government — with lead agency status — and the Federal Government, which has granted the project Major Project Status. The SAFELOOP qualification provides market validation for the flowsheet's ability to consistently produce >4N+ purity HPA at repeatable quality.

Outlook

The qualification of premiumHPA within SAFELOOP is described by management as establishing a potential pathway to binding offtake arrangements. The company's Managing Director, Roland Hill, noted that the commercial application of premiumHPA is no longer in question, and that the qualification significantly advances the commercial positioning of the project. The near-term focus will be on converting the qualification milestone into commercial supply discussions, progressing project financing Options, and continuing development of both the HPA and Minhub rare earths projects.
