Altech Batteries Limited has announced that a major global battery manufacturer has begun formally assessing its Silumina Anodes technology, marking what the company describes as a significant step forward for its manufacturing development efforts.
In an ASX statement, Altech said the electric-vehicle battery producer initiated the engagement, signing a mutual Non-Disclosure Agreement to enable confidential technical evaluation.
According to Altech, samples of its silicon-enhanced anode material have been manufactured and shipped to the battery group’s laboratories in China for testing.
Altech reported that early industry feedback highlighted the performance of its alumina-coated silicon, noting that “across the industry they have not yet seen silicon additions deliver such meaningful performance improvements at low percentages.”
The company said the battery group also acknowledged that only a small number of suppliers globally are producing silicon additives with comparable stability and consistency.
As part of the collaboration, the battery manufacturer has asked Altech to conduct coating trials on graphite it supplied.
Altech confirmed that several kilograms of the material have been delivered to its Perth laboratory, where its team will apply the company’s proprietary alumina-coating process before returning the samples for benchmarking.
Altech also provided an update on ongoing long-cycle testing, stating that the latest results show 83 per cent capacity retention after 1,000 charge–discharge cycles using a 5 per cent Silumina Anodes addition to a standard graphite anode.
The company described this as a milestone that confirms the durability and commercial potential of its manufacturing approach to silicon-enhanced anodes.
Managing Director Iggy Tan said the engagement reflects strong interest from industry. “This engagement from the world’s largest battery manufacturer is a powerful validation of our Silumina Anodes™ technology,” he said.
“Their early feedback, particularly noting they have not seen silicon additions perform this effectively at such low levels, reinforces the significance of our breakthrough.”
