The Altech GridPacks have been specifically engineered to adhere to the Ingress Protection (IP) 65 standard (relating to a high level of electrical enclosure sealing), ensuring complete protection from both dust and inclement weather. This means that there is no need for any additional shelters or buildings to house the Altech GridPack batteries, and they can be safely installed outdoors in any weather conditions. The Altech GridPacks will be constructed using a sea container design, which facilitates their easy transportation by sea or road to the installation site, as well as ensuring simple installation.

The “plug and play” feature of the site installation for the GridPacks ensures that they can be easily installed in remote locations. Additionally, the containers have been designed to be stackable, which minimizes the battery footprint (refer to Figure 2). Unlike other mega battery pack designs on the market, these GridPacks can be stacked on top of each other. This stackable feature, coupled with the “plug and play” design, makes the GridPacks easily scalable and adaptable to meet future energy storage requirements of the site.

Furthermore, the Altech GridPacks are designed without the requirement for any moving parts such as cooling fans, which are typically found in lithium-ion battery mega packs. This is a notable advantage as end-use customers have raised concerns about the noise generated by mega packs, preventing them from being placed near residential areas. With the absence of any moving parts, the Altech GridPacks are completely noise-free operation, making them an ideal solution for noise-sensitive environments. Finally, GridPacks are extremely low in maintenance costs over the battery life.

The Altech 1 MWh GridPacks are designed to operate in any climate, without the need for thermal management. The battery's internal temperature remains relatively constant throughout the charging and discharging cycles, due to its endothermic and exothermic properties. These 1 MWh GridPacks will offer significant benefits for the fast growing renewable energy and grid storage sectors. These larger battery packs are capable of storing more energy, resulting in more efficient utilisation of renewable energy sources such as wind and solar power.

Altech believes that the proposed GridPacks are an excellent means of stabilising the grid by providing a source of backup power during periods of high demand or when renewable energy sources are not producing at capacity. They are also a cost-effective solution for storing and distributing renewable energy across a variety of applications, including grid-scale storage, microgrids, and electric vehicle charging.

Altech Batteries Ltd CERENERGY Type Battery Shows 28 Year Shelf Life

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) (OTCMKTS:ALTHF) is pleased to announce the exceptional long-term shelf life of its CERENERGY(R) sodium-nickel-chloride (Na Ni-Cl) battery technology.

Highlights

- CERENERGY(R) has been designed on well-established sodium-nickel-chloride chemistry

- Origins to the first-generation Zebra batteries

- 28-year-old Zebra battery, left unused in storage, provided to Altech

- Upon testing, battery performed as if it were new

- No degradation in function or capacity despite nearly three decades of dormancy

- Ideal for long-term military storage

CERENERGY(R) batteries have been designed on well-established sodium-nickel-chloride chemistry, which traces its origins to the first-generation Zebra batteries. These earlier Zebra cells had a smaller energy capacity (approximately 100Wh) compared to the current CERENERGY(R) cells (250Wh). CERENERGY(R) cells were developed to improve energy capacity and reduce battery costs, but share the same fundamental Na Ni-Cl electrochemical design.

In a compelling demonstration of the technology's durability, a 28-year-old Zebra battery- originally manufactured by AEG ZEBRA in Berlin and left unused in storage-was recently provided to Altech for evaluation. Upon testing, the battery was successfully activated and performed as if it were new, exhibiting no degradation in function or capacity despite nearly three decades of dormancy.

The underlying reason for this remarkable longevity lies in the battery's unique chemistry and solid-state design. In its inactive state, the battery's electrolyte exists as solid sodium aluminium chloride salt crystals and nickel powder. All components are contained within a hermetically sealed, pressure-tight cell, preventing any moisture ingress or chemical degradation. Unlike conventional lithium-ion batteries-which rely on volatile liquid electrolytes that degrade over time-the CERENERGY(R) system remains completely inert and stable at ambient conditions.

When activated by heating to approximately 270 degC, the 28-year-old Zebra battery transitions into its operational state and can immediately begin charging and discharging with no observable loss in performance. This "on-demand activation" feature makes it particularly appealing for defense and strategic reserve applications, where batteries may need to be stored for extended periods and rapidly deployed when needed. In fact, such systems could be buried underground or warehoused for decades and reactivated without any compromise in performance.

To validate this capability further, Altech's joint venture partner, Fraunhofer IKTS, has conducted a rigorous individual cell stress-testing program. The 28-year-old cell is currently undergoing daily charge and discharge cycling at 300 degC across a 20-80% state of charge (SoC) range. The tests confirm not only the battery's safe operation but also its consistent performance across the full capacity spectrum.

This breakthrough reaffirms the robustness, safety, and strategic advantage of CERENERGY(R) sodium-nickel-chloride battery technology, setting it apart from conventional storage solutions in terms of reliability and long-term stability.

VIDEO: Altech Batteries Ltd Silumina Anodes Project Update

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC) (FRA:A3Y) (OTCMKTS:ALTHF) is pleased to provide an update of the Silumina AnodesTM Project. This Company's game changing technology incorporates high-capacity silicon into 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. The Company's proprietary silicon product is registered as Silumina AnodesTM.

Highlights

- Spherisation of coated silicon particles- newest technological development

- Positioned in voids of graphite layer - further reducing impact of swelling

- Optimised 5% silicon content gives 50% capacity increase

- Pilot plant in Germany now operational

- All challenges resolved and ready for customer testing

SPHERISATION OF COATED SILICON

As previously noted, key challenges in using silicon in lithium-ion battery anodes include particle swelling, first-cycle capacity loss of up to 50%, and rapid battery degradation. Altech's initial approach involved coating individual silicon particles with a nanolayer of alumina to reduce expansion and mitigate first-cycle loss. This method proved effective. Building on this success, the next phase of development involved spherifying the coated silicon particles and applying additional coatings to the spherical structures (refer Figure 1*). These spherical, alumina-coated silicon particles can be effectively distributed within the voids of graphite, helping to minimise long-term damage to the electrode layer caused by expansion (refer Figure 2*). By residing in these voids, the particles can move without exerting stress on the surrounding graphite sheets. Additionally, the Company's R&D laboratory has optimised silicon content to a 5% addition, which has delivered a 50% capacity performance improvement in battery applications. The improvement in battery anode capacity can be seen in Figure 3 and 4*.

SUCCESSFUL PILOT PLANT OPERATION

Altech is in a race to get its patented technology to market. To support the development, Altech constructed a pilot plant adjacent to the proposed project site to enable the qualification process for its Silumina AnodesTM product. Coated silicon products are now being successfully produced at the Company's pilot plant located at Dock 3 in Saxony, Germany. The commissioning process presented a number of technical challenges, primarily related to the equipment delivery delays, supply of SiC materials, poor flowability and handling difficulties of the ultra-fine silicon powders used in the process - particles measuring less than one micron in size. These powders tended to cause hang-ups and blockages within the system, complicating consistent material movement and process stability. However, through a combination of engineering adjustments and process optimisations, these issues have now been resolved. The pilot plant is now operational and has produced high-quality coated silicon particles. These products are ready for evaluation and testing by potential customers, marking a key milestone in the commercialisation pathway.

Group Managing Director Iggy Tan said "The next generation of our development, leveraging spherization technology, has successfully addressed the long-standing challenges of silicon-namely swelling and rapid degradation. We've achieved a battery with 50% higher energy density and enhanced cycle life, all with a modest addition of silicon. Our proprietary alumina-coated, spherical silicon particles represent a breakthrough in battery anode materials. Production at our pilot plant in Saxony marks a significant milestone, and we are actively engaging with potential customers for evaluation. This progress places Altech at the forefront of next-generation battery technology as we move toward commercialisation."
