Altech Advanced Materials AG: Extended patent protection for battery material technology applied for

Heidelberg (pta018/07.06.2022/10:15 UTC+2)

  • Ongoing patent application for Silumina Anode™ battery material technology moves to next phase
  • Further patent applications filed for core markets USA, Europe, China, Japan and Korea as well as international patent application in principle for up to 156 countries

Altech Advanced Materials AG (AAM / the Company) (FRA: AMA1), a publicly traded company, announces that additional patent applications have been filed through the Altech Group to protect intellectual property related to the application of the Silumina Anode™ battery material technology and aluminum coating process. On May 13, 2022, patent applications were filed in the United States, Europe, China, Japan and Korea. In addition, an international patent application was also filed, allowing the right to file national applications in up to 156 countries. These broader applications are based on the Australian patent application filed on May 13, 2021. After a one-year period, there is an opportunity to file extended patent applications based on the ongoing patent process in Australia, which was taken up by the Altech Group.

Altech's anode material is to be marketed under the proprietary Silumina Anode™ brand. Silumina Anodes™ is to be produced at Altech Industries Germany GmbH's (AIG) battery coating plant to be built in Schwarze Pumpe in Saxony, Germany, with a capacity of 10,000 tons per year. To accelerate development, the company is currently building a pilot plant next to the future factory to provide battery manufacturers with appropriate material for testing and qualification purposes at an early stage. AIG is a joint venture between AAM (25%) and Altech Chemicals Limited, Australia (75%).

The patent applications protect Altech's process for coating anode materials such as silicon and graphite with nano-layers of aluminum, for which AIG holds exclusive EU-wide rights. The coatings can reduce lithium losses during each battery charge and discharge cycle, as well as delay battery capacity degradation over the life of the battery. Through proprietary research and development, the company has successfully developed a battery with 30% higher performance and lifetime. Higher density batteries result in smaller, lighter batteries and significantly lower greenhouse gases, and are the future for the electric vehicle market. The patent applications now filed are intended to protect Altech's intellectual property extensively to leverage the economic potential of this battery innovation for years to come.
