Altech Chemicals Ltd (ASX:ATC) has made further patent filings to protect its intellectual property relating to the application of Silumina Anodes™ battery materials technology and alumina coating process.
On May 13, 2022, an international patent application preserving the right to file national applications in up to 156 countries was filed.
National patent applications have also been filed in the United States, Europe, China, Japan and Korea.
Australian application
Altech says that these patent applications claim priority from the Australian provisional patent application that was originally filed on May 13, 2021.
The company has broadened the patent filings in order to extend reach and protection of the technology and this current round of filings further demonstrates Altech’s commitment to protecting its intellectual property.
Protecting Altech process
These patent applications protect Altech’s process for covering anode materials such as silicon and graphite with nano-layer alumina coatings.
The coatings serve as an artificial solid electrolyte interface (SEI) and can reduce lithium loss during each battery charge and discharge cycle, and also retards degradation of battery capacity throughout battery life.
About Altech Chemicals
Altech Chemicals is a specialty battery materials technology company that has licensed its proprietary high purity alumina coating technology to 75%-owned subsidiary Altech Industries Germany GmbH (AIG).
AIG has commenced a definitive feasibility study for the development of a 10,000 tonnes per annum silicon/graphite alumina coating plant in the state of Saxony, Germany to supply its Silumina Anodes™ product to the burgeoning European electric vehicle market.
This company recently announced its game-changing technology of incorporating high-capacity silicon in lithium-ion batteries.
Through in house R&D, the company has cracked the ‘silicon code’ and successfully achieved a 30% higher energy battery with improved cyclability or battery life.
Higher density batteries result in smaller, lighter batteries and substantially less greenhouse gases and is the future for the EV market.
The company’s proprietary silicon graphite product is registered as Silumina Anodes™.
