Altech Batteries (ASX: ATC) has initiated a non-disclosure agreement with a leading global battery manufacturer for the technical exchange and evaluation of materials relating to its high‑performance silicon‑enhanced anode technology.
Under the terms of the collaboration, Altech will prepare and supply Silumina Anodes samples to the counterparty for formal testing at its advanced evaluation laboratories in China.
Altech believes its recent latest test results of 83% capacity retention after 1,000 charge–discharge cycles places its Silumina Anodes material at the forefront of next-generation silicon-enhanced anode technologies, and strengthens its position in the global battery materials market.
Previous Silicon Challenges
Previous attempts to integrate silicon into commercial lithium‑ion anodes struggled to overcome numerous challenges including expansion-related degradation, unstable solid‑electrolyte interphase formation, and rapid cycle‑life fade.
The strong performance of Altech’s coated silicon, achieved with only modest silicon loading led the manufacturer to acknowledge that very few material suppliers globally were producing silicon additives with such a high level of stability, consistency, and real‑world applicability.
In return, the counterparty has supplied several kilograms of representative graphite samples to Altech’s Perth laboratory for coating and evaluation trials under the leadership of chief technical officer Dr Jingyuan Lu to assess the performance impact of integrating Altech’s proprietary alumina technology directly onto the anode substrate.
The coated graphite samples will then be returned to the manufacturing group for benchmarking against its internal standards, providing a direct comparison of how Altech’s technology enhances its preferred graphite formulations.
Growing Global Recognition
Altech managing director Iggy Tan said the non-disclosure agreement underscored growing global recognition of the potential of its alumina‑coated silicon innovations.
“Our engagement with the world’s largest battery manufacturer is a powerful validation of our Silumina Anodes technology,” he said.
“The early feedback — highlighting that they have not seen silicon additions perform this effectively at such low levels — reinforces the significance of our breakthrough."
“We look forward to demonstrating how our coating technology can further enhance battery graphite and anode performance.”
