ALTECH CHEMICALS LIMITED (ASX: ATC) (Altech or “the Company”) has announced its further patent filings to protect its intellectual rights over its Silumina AnodesTM battery technology. Silumina AnodesTM is an alumina coated composite silicon and graphite battery anode that can be integrated into lithium-ion batteries to provide higher energy retention capacity. As the proprietary product of Altech, THE COMPANY has filed both national and international patents to preserve its intellectual property.
Patent Applications
- Patent application in Australia
Altech filed a National patent in Australia on 13 May 2021. The patent covers BOTH the Silumina AnodesTM technology as well as the invention methods for coating anode-active materials with alumina.
- Patent applications in other countries
Altech has also filed national patent applications in the United States, Europe, China, Japan, and Korea. These applications claim priority citing the Australian provisional patent from 13 MAY 2021.
- International patent applications
In addition to individual national patents, Altech has also filed an international patent on 13 May 2022. The international patent application provides Altech with the right to apply for national patents in 156 countries.
All patent applications are aimed at protecting ALTECH’S intellectual property including the developed and prototype technology, products as well as innovative methods. All filed patent applications include the Company’s process for coating anode materials (such as silicon and graphite) with nanolayer alumina.
The Company stated “This round of patent filings shows ALTECH CHEMICALS’ commitment to protecting its intellectual property.”
About the Proprietary Product
Since the alumina coating serves as an artificial solid electrolyte interface, it has been shown to reduce lithium loss in the battery during charge and discharge cycles. This result, as well as Silumina AnodesTM other properties, including energy retention capacity with volume and weight of the battery and battery life, ensures that this technology remains as proprietary. This is further outlined in the Preliminary Feasibility Study for the Silumina AnodesTM project announced in APRIL 2022. The current round of patent filings covers all these properties as well.
