Heidelberg (pta031/29.04.2021/13:00) - Highlights
* Collaboration agreement with leading German based graphite producer
* Alumina coated graphite for lithium-ion battery industry
* Applying Altech HPA and coating technology
* Altech now at forefront of graphite HPA coating technology
* In addition, renewed MOU with SGL Carbon for engineering support for the design, production, and supply of HCl treatment systems

Altech Advanced Materials AG ("AAM"/the Company), (FRA: AMA1) is pleased to announce that its partner Altech Chemicals Limited, Australia ("ATC") together with its joint venture Altech Industries Germany GmbH ("AIG"), in which AAM holds a 25% interest, (collectively "Altech") has signed a collaboration agreement with SGL Carbon GmbH (SGL Carbon), a wholly-owned subsidiary of SGL Carbon SE of Germany. The agreement is to collaborate and support Altech's development of high purity alumina coated graphite materials specifically targeted for use by the lithium-ion (Li-ion) battery industry. SGL Carbon SE is a world leader in the development and production of carbon-based solutions and reported sales of 919 million Euros in 2020.

Also, Altech and SGL carbon have renewed their memorandum of understanding for engineering support covering design, production, and supply of HCl treatment systems to be used in Altech's HPA project in Malaysia, and potentially in Germany.

On 22 December 2020, Altech announced the successful demonstration of its alumina coating technology - the coating of graphite particles typical of those used in anode applications within lithium-ion batteries (anode grade graphite), with a nano layer of high purity alumina (HPA). The demonstration showed that Altech's technology was able to deposit a uniform and consistent layer of alumina onto anode grade graphite particles. The uniformity and consistency of an alumina layer on anode grade graphite is expected to be important to improve lithium-ion battery performance. On 12 February 2021, Altech announced the commencement of a pre-feasibility study (PFS) by its 75% owned German subsidiary Altech Industries Germany GmbH, for the construction of a battery materials high purity alumina (HPA) coating plant in Saxony, Germany. The PFS will assume a phase 1 coating plant designed with the capacity to coat 10,000tpa (35tpd) of anode graphite. On 8 March 2021, the Company completed the first phase of battery performance testing of graphite particles coated with HPA. Results for the coated graphite anodes compared to the non-coated anodes were positive and encouraging.

"I believe that Altech's coating technology can be successfully employed to coat SGL Carbon's various battery graphite powders with a uniform nano-layer of alumina. Under this collaboration agreement, Altech and SGL Carbon will test the use of Altech's technology to coat SGL Carbon's specifically designed graphite particles with high purity alumina (HPA). Both companies will fund the test work and retain their respective intellectual property", said Altech's managing director, Mr Iggy Tan.

About Altech Advanced Materials AG

Heidelberg-based Altech Advanced Materials AG (ISIN: DE000A2LQUJ6), which is listed on the stock exchange, holds a stake in Altech Industries Germany, which is setting up a first production site for the nanocoatings of graphite and/or silicon particles in Germany in Saxony. Nanocoatings with high-purity aluminum oxide can prevent the normal power loss of about 8 percent during initial charging of a lithium-ion battery. In addition, the service life can be extended by up to 20 percent and the fast-charging behavior can be improved by the aluminum oxide coatings. Final product testing for the patent-protected technology is underway. AAM is also integrated into the international production activities of Altech Chemicals Ltd, Australia, resulting in additional opportunities in the growth sector of alumina. The companies, collectively known as the Altech Group, are technology leaders in the optimization of batteries for electric mobility. Further information at:
