Altech Batteries successfully commissions pilot plant in Germany for Silumina Anodes production
Breakthrough in spherisation of coated silicon particles leads to enhanced battery performance
Silumina Anodes project progresses towards full-scale production and customer qualification
Altech Batteries Ltd (ASX:ATC), listed within the ASX 200 technology sector, has reported a major milestone in its Silumina Anodes project, achieving commercial sample production from its newly commissioned pilot plant in Germany. The development is part of the company’s broader aim to innovate lithium-ion battery materials with improved energy characteristics.
Silumina Anodes Product Advances with In-house Innovation
The Silumina Anodes material is the result of extensive internal research and development focused on integrating silicon into battery anodes. This integration aims to enhance energy storage and cycle life in lithium-ion batteries. The product is now being manufactured at pilot scale and is available for customer qualification processes.
Altech’s latest achievement involves the spherisation of alumina-coated silicon particles, a process that helps mitigate common challenges like swelling and structural degradation. These spherical particles are engineered to fit within graphite matrix voids, improving mechanical stability and electrode performance. The company reports significant improvements in anode capacity using a silicon-graphite formulation.
Pilot Plant Commissioned in Saxony with Commercial Objectives
The pilot plant, situated at Dock 3 adjacent to Altech’s proposed commercial-scale facility in Saxony, Germany, has overcome multiple engineering and supply chain hurdles. These included delayed equipment arrivals, inconsistent raw material supplies, and processing difficulties associated with the handling of ultra-fine silicon powders. These powders, smaller than one micron, led to flow-related disruptions and operational delays.
Design refinements and technical optimisations implemented by Altech’s engineering team have now stabilised the process. The plant is currently producing coated silicon particles for customer evaluation, marking a significant step forward in product validation and market readiness.
Customer Engagement and Path to Full-Scale Production
With the pilot facility fully functional, Altech is now entering a customer qualification phase. The company has signed non-disclosure agreements with multiple automotive and battery manufacturing entities across Germany and North America. These agreements facilitate formal testing of Silumina Anodes materials, which are being supplied in commercial sample volumes.
The long-term vision includes scaling up to a full-capacity plant in Saxony, designed to support increasing demand for high-performance battery anodes. The planned commercial facility has secured green accreditation and benefits from a stable European silicon sourcing network.
Altech Batteries continues to advance its position within the battery materials space, aligning its operations with growing demands in energy storage, electric mobility, and the broader ASX 200 technology landscape.
