Altech Batteries Ltd (ASX:ATC) (FRA:A3Y) highlighted encouraging quarterly performance in its December 2025 report, unveiling breakthrough results for its Silumina Anodes™ technology. The proprietary alumina-coated spherical silicon anode material achieved an impressive 88.5% capacity retention after 500 charge-discharge cycles with just 5% silicon anodesTM addition, strongest cycling performance recorded till date. This milestone bolsters Altech's battery development efforts, supported by a fresh AUD 6 million capital raise to advance battery projects.
Silumina Anodes™ Deliver High Cycle Retention
Testing of Altech’s proprietary alumina-coated spherical silicon material demonstrated 88.5% capacity retention after 500 cycles when blended at a 5% addition into a graphite anode. Notably, repeated testing returned retention levels above 88.0% (at same interval), confirming reproducibility and consistency of the manufacturing process.
The silicon-enhanced anodes delivered an initial capacity of 500 mAh/g, exceeding that of commercial graphite anodes by more than 40%. After 500 cycles, capacity remained at 420 mAh/g, which is greater than 60% of the capacity typically achieved by graphite-only cells over the same cycle life. Higher anode capacity allows for extended electric vehicle driving range, reduced battery pack weight, and enhanced efficiency.
Silicon can store up to ten times more lithium than graphite, offering increased energy density. Altech’s alumina coating technology addresses common silicon-related challenges by reducing swelling induced electrode degradation.
AUD 6m Placement Funds Battery Programs
During the quarter, Altech completed a AUD 6 million capital raising through the issue of 133,333,334 shares at an issue price of AUD 0.045 per share.
Funds from the placement will support project financing activities for the 120 MWh CERENERGY® sodium solid-state battery facility in Germany, completion of a 90 kWh battery prototype, and preliminary assessment of a proposed 4 GWh gigafactory.
Board Appointments and Strategic Focus
The quarter also saw changes to the Board and management. Daniel Raihani was appointed Managing Director and Chief Executive Officer, with Giuseppe Graziano joining as Chairman. Hansjoerg Plaggemars remains a Non-Executive Director, while Martin Stein continues as Chief Financial Officer and Company Secretary.
The Board has confirmed its strategic focus on advancing Silumina Anodes™ and CERENERGY® battery systems, while identifying partners to support commercial deployment. A comprehensive strategic reset has commenced to position Altech for successful commercialisation of its core battery technologies.
With record-setting Silumina Anodes™ performance and a strengthened capital position, Altech Batteries is well-placed to accelerate the development and commercialisation of its advanced battery technologies. The combination of proven high-cycle silicon anode performance, ongoing CERENERGY® battery programs, and a strategically reset Board positions the company to unlock long-term value in the rapidly growing energy storage and electric vehicle markets.
ATC shares were trading at AUD 0.028 per share at the time of writing on 29 January 2026.
