Altech Batteries Ltd Silumina Anodes Plant Calciner Design & Layout

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) provides an update to designs on its cutting-edge Silumina AnodesTM pilot plant project in Saxony, Germany, as well as the Definitive Feasibility Study for the planned Silumina AnodesTM 10,000tpa plant.

The Company has completed the final design phase for the front-end calciners as well as the corresponding plant layout. To complete the Definitive Feasibility Study, a more comprehensive engineering design was necessary, for it to be sourced and priced from suppliers. The calciners, which have been designed in- house, are of the packed bed type and are intended to operate at temperatures around 600 degrees Celsius. These calciners play a crucial role in the Silumina AnodesTM process, wherein they facilitate the conversion of aluminum chloride present on the surface of graphite and silicon particles into alumina. This innovative coating technology has been developed by Altech. Notably, a distinctive feature of these calciners is the utilisation of 3D-printed silicon carbide linings. These linings are employed to effectively handle the acidic atmosphere during the calcination process. Altech's process places significant emphasis on managing impurities, highlighting its importance in the overall production process.

The design of the calciner and cooler has progressed to a more advanced stage by incorporating manufacturing and stress test data from the research plant's component production and testing phase. This evolution in design has resulted from comprehensive testing that has refined the dimensions of the dryers, calciners, and coolers for the DFS. The finalised design now consists of two dryers and a four-circuit calciner/cooler configuration. The geometry of the calciners and cooler has undergone refinement, leading to the optimisation of a twin-chamber design. This design choice results in lighter modules that facilitate both assembly and maintenance processes. Additionally, the components have been meticulously designed to remain within the constraints of available manufacturing equipment size and capabilities.

Efforts to advance manufacturing discussions are underway, with ongoing detailed conversations held with leading Silicon Carbide (SiC) vendors in Europe, strategically located in proximity to the Spreetal plant. These discussions center around the suitability of the DFS plant design for 3D printing, encompassing aspects such as material selection optimisation, manufacturing processes, standardisation, and production consistency.

Considering the specialised demands of the battery coating process, the manufacturing techniques required are cutting-edge and incorporate the latest advancements in SiC industry technology. This dynamic collaboration involving Altech, Australian designers, Specialist Dryer technology Vendors, and German manufacturers has paved the way for continuous development of the SiC components essential for the drying and calcination phases.

Permitting Process

The advancement of the Silumina AnodesTM Definitive Feasibility Study is on track, and notable progress has been made. The Company has obtained final quotations from essential suppliers, and work on the conclusive design of civil and site infrastructure is currently underway. Concurrently, Arikon has initiated initial dialogues with regulatory authorities to initiate the permitting process for the Schwarze Pumpe project. Up to this point, favourable cooperation and backing have been observed from both local authorities and regulatory entities.

The Company has previously concluded a Preliminary Feasibility Study concerning the establishment of a 10,000tpa Silumina AnodesTM plant located in Saxony, Germany, which has yielded a remarkable NPV of US$507M. As Altech accelerates its efforts to introduce its patented technology to the market, it has initiated the construction of a pilot plant in close proximity to the intended project site. This pilot plant's primary objective is to support the qualification process for the Silumina AnodesTM product. It will have the capability to supply interested customers with commercial samples to facilitate their testing and qualification procedures.

VIDEO: Altech Batteries Ltd Silumina Anodes Project DFS Expands Output 8-Fold to 120GWh

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) is pleased to announce that during the finalisation of the Silumina Anodes TM project Definitive Feasibility Study (DFS), Altech has managed to expand the project's output by eightfold, increasing the capacity from 15 gigawatt-hours (GWh) to 120 GWh, with no change to plant and equipment. This significant expansion will effectively cater to the long-term demand for silicon-type anodes within the industry.

Initially, as per the original DFS scope, Altech had proposed the production of 10,000 tons per annum (tpa) of Silumina Anodes TM product, comprising 1,000 tpa of high-purity alumina-coated metallurgical silicon incorporated into 9,000 tpa of similarly coated graphite (10% mix). The plant will now focus on solely producing alumina-coated metallurgical silicon product at a rate of 8,000 tpa. This product will be integrated into the graphite by the customers within their battery plants rather than at Altech's facility.

As a result of this increased production of the 'active' component, the output has expanded by a significant eightfold, rising from 15 GWh to 120 GWh.

According to feedback from potential customers, utilising their existing qualified graphite source is a priority.

Furthermore, although there is a marginal advantage in using alumina-coated graphite, the primary appeal for potential customers lies in integrating Altech-coated silicon into their battery products. Despite initial considerations regarding the benefits of coating graphite with alumina, such as the reduction of first-cycle loss, Altech's research has demonstrated that the cost-to-reward ratio for graphite is relatively minimal.

This recent adjustment to "all silicon" is expected to yield substantial improvements in the bottom-line economics. The most notable advantage lies in the ability to crack the silicon code, preventing expansion defragmentation, as well as curbing the significant first-cycle loss associated with silicon.
Battery manufacturers have the choice to either produce batteries with higher energy density or maintain their current energy density while reducing the graphite content. By decreasing the use of graphite, the cost of producing batteries can be reduced. However, the recent news about China, which accounts for approximately 90% of the global production of lithium-ion battery graphite, imposing limitations on the worldwide export of graphite, has begun to create challenges for battery manufacturers in Europe and the USA.

Altech is currently in talks with Ferroglobe, the European silicon partner of Altech, to boost the supply of metallurgical silicon for the enhanced Silumina Anodes TM project. Moreover, the Company has executed non-disclosure agreements (NDAs) with prominent automotive conglomerates in Europe and the United States, who have shown keen interest in acquiring commercial samples for their testing and qualification procedures. Considering the limited production capacity of Altech's R&D laboratory in Perth, the larger samples will be procured from the Silumina Anodes TM Pilot Plant in Saxony. The Pilot Plant is nearing completion and is expected to be operational in the early part of the upcoming year.

Managing Director Iggy Tan emphasised that the substantial increase in Silumina Anodes TM output by eightfold, achieved without significant changes in the plant or capital costs, represents a notable advancement in Altech's business strategy. Mr Tan highlighted the increasing demand in the lithium-ion battery industry for higher-density batteries, emphasising the necessity to reduce reliance on graphite, particularly in light of the export restrictions imposed by China. Mr Tan expressed confidence that the incorporation of Altech's alumina-coated silicon would assist battery customers in addressing these concerns. Mr Tan further conveyed his enthusiasm regarding the enhanced business model, indicating a positive outlook for the company's future endeavours.

Altech Batteries Ltd CERENERGY Battery Project Upgraded to 120MWh

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) is pleased to announce that, after the final stages of facility design, the Company has successfully increased the output capacity of the CERENERGY(R) project from 100 MWh to 120 MWh per annum. This enhancement was achieved with the lead engineering company Leadec and joint venture partner Fraunhofer.

Through technical design optimisation, the plant output has been enhanced by 20% without incurring any additional capital costs. Consequently, the annual output will now reach 120 1MWh GridPacks. Despite the relatively small size of the plant, most equipment sizes were standard off-the-shelf capacities, offering ample additional capacity. Upon reviewing the equipment throughput with each supplier, Leadec has advised that the rated output of the plant can be conservatively increased to 120 MWh.

In a recent announcement, Altech revealed the updated design of the 60 KWh battery pack, now featuring a sleek stainless-steel exterior instead of the previous blue paint. This modification has instilled a greater sense of confidence, as the stainless-steel finish is expected to withstand extreme temperature variations better, whether in snowy or desert conditions, whilst maintaining its pristine appearance.

A significant design update involves the stacking method of the 1MWh GridPacks. The enhanced design now permits triple stacking and facilitates seamless interconnection between each GridPack. These GridPacks can be conveniently stacked atop one another, using a simple electrical connection. The connection leads will be incorporated within the GridPack frames, enabling an effortless "plug and play" setup. This configuration allows for the parallel or series connection of GridPacks to augment the operational voltage. This ingenious design substantially minimises the space occupied by grid storage battery packs and eliminates the necessity for separate cooling airflow around the GridPacks, conserving valuable land area. These advantages position the CERENERGY(R) GridPacks as a more advanced alternative to lithium-ion battery solutions.

Group Managing Director Iggy Tan commented on the DFS upgrade to 120 MWh annually. "From the beginning, we recognised a considerable margin built into the different equipment designs. Initially, our approach to facility design was quite conservative. However, as we've progressed in finalising the overall equipment operations, it has become evident that we possess the capability to increase our production rate.

We are currently in the final stages of the DFS, where we are meticulously reviewing all cost factors, including operating consumables and purchased items" he said.
