Encouraging Phase 1 Battery Performance Tests

Perth, Mar 8, 2021 AEST (ABN Newswire) - Altech Chemicals Limited (googlechartASX:ATC) (googlechartA3Y:FRA) is pleased to advise that it has now completed the first phase of battery performance testing of graphite particles coated with high purity alumina (HPA), using Altech's proprietary coating technology.
Highlights

- First phase of 100 cycle battery tests completed

- Coated graphite performance is encouraging and meets expectations

- Further test runs to demonstrate repeatability

- Potential improvements to lithium-ion battery life, capacity and chargeability

For the first round of testing, a batch of battery electrodes were produced using non-coated standard anode grade graphite particles (the control), and a separate batch was produced that contained anode grade graphite particles coated with HPA using Altech's technology. One hundred cycles of cell charge and discharge were completed. Results for the coated graphite anodes compared to the non-coated anodes were positive and encouraging. Test work will now proceed to the next stage where additional runs of battery charge and discharge will be undertaken with the aim of obtaining results that demonstrate repeatability and consistency.

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 an 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, the Company announced the commencement of a pre-feasibility study 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 battery test results will be incorporated into the study.

The battery test work is part of the Company's strategy to focus on tailoring its high purity alumina into specialised products targeted at more efficient applications within the lithium-ion battery industry.

Altech's General Manager Operations and chief scientist, Dr Jingyuan Liu was very encouraged by the initial phase of results, "We now have to optimise the testing conditions and conduct additional tests to demonstrate repeatability and consistency. The performance of the alumina coated graphite is meeting our expectations so far", he said.

About Altech Batteries Ltd

Altech Chemical Ltd ASX:ATCAltech Batteries Limited (ASX:ATC) (FRA:A3Y) is a specialty battery technology company that has a joint venture agreement with world leading German battery institute Fraunhofer IKTS ("Fraunhofer") to commercialise the revolutionary CERENERGY(R) Sodium Alumina Solid State (SAS) Battery. CERENERGY(R) batteries are the game-changing alternative to lithium-ion batteries. CERENERGY(R) batteries are fire and explosion-proof; have a life span of more than 15 years and operate in extreme cold and desert climates. The battery technology uses table salt and is lithium-free; cobalt-free; graphite-free; and copper-free, eliminating exposure to critical metal price rises and supply chain concerns. 

The joint venture is commercialising its CERENERGY(R) battery, with plans to construct a 100MWh production facility on Altech's land in Saxony, Germany. The facility intends to produce CERENERGY(R) battery modules to provide grid storage solutions to the market.
