Altech Batteries Ltd CERENERGY Battery Prototype Reaches Key Milestones

Perth, Australia (ABN Newswire) - Altech Batteries Limited (ASX:ATC,OTC:ALTHF) (FRA:A3Y) (OTCMKTS:ALTHF) is pleased to announce the latest performance results of the CERENERGY(R) cell and battery pack prototypes. These results confirm the technological maturity and robustness of the CERENERGY(R) technology and mark another decisive step towards industrialisation.

Highlights

- 650+ cycles with no capacity loss, proving exceptional material stability and long operational lifespan compared to conventional batteries

- Near 100% Coulombic efficiency, confirming minimal side reactions and strong intrinsic safety of sodium nickel chloride chemistry

- High energy efficiency of up to 92%, surpassing typical 70-80% levels of competing battery technologies

- Proven safety under extreme conditions - cells remained stable during overcharge, deep discharge, and thermal cycling up to 300 degC with no gassing, leakage, or rupture

- Robust and reliable chemistry - sodium nickel chloride avoids flammable electrolytes and runaway risks, confirming suitability for safe, large-scale grid and renewable energy storage

- ABS60 prototype validated under real-world conditions -tested across diverse load profiles, high-current pulses up to 50 A, and thermal variations

- Stable, efficient performance - achieved ~88% round-trip efficiency with no observable capacity fade over 110+ cycles

CELL PERFORMANCE

The CERENERGY(R) prototype cells have successfully completed over 650 charge-discharge cycles without any detectable capacity loss. Cycle life is a critical measure of battery durability, as most conventional batteries experience gradual degradation with every cycle. Achieving such performance highlights the outstanding stability of the materials and points to the potential for a long operational lifespan.

For stationary energy storage systems (ESS), this translates into fewer battery replacements, lower lifetime operating costs, and greater reliability for end users.

The cells also delivered nearly 100% Coulombic efficiency alongside an energy efficiency of up to 92% across 650 cycles. Coulombic efficiency reflects the proportion of charge recovered during discharge relative to what was supplied during charging. A value approaching 100% indicates minimal side reactions or parasitic losses, confirming the intrinsic stability and safety of sodium nickel chloride chemistry. This high efficiency demonstrates that the cells are not expending energy on unwanted processes such as electrode degradation. Such performance is vital for scalability, ensuring reliable, longterm operation in commercial energy storage applications.

Energy efficiency represents the proportion of energy delivered relative to the energy supplied. Competing technologies, including conventional high-temperature batteries and many flow batteries, typically achieve only around 70-80%. By reaching 92%, CERENERGY(R) positions itself in a highly competitive class, offering more cost-effective energy storage, stronger economics for grid operators, and seamless compatibility with the requirements of renewable energy integration.

The cells achieved a nominal capacity of 100 Ah and 250 Wh, with reliable performance even at higher discharge rates. A key feature is their ability to support multiple daily charge-discharge cycles within the 20-80% state of charge (SoC) range at 25 A. This capability positions CERENERGY(R) as a highly flexible solution for grid operators and energy storage providers, enabling cost-efficient, long-life performance in applications that demand frequent cycling such as renewable integration, peak shaving, and backup power.

CERENERGY(R) prototype cells underwent rigorous abuse testing, including overcharge to 4 V, deep discharge to 0.2 V, and thermal cycling between room temperature and 300 degC. In all cases, the cells remained stable with no gassing, leakage, or rupture -clear proof of their outstanding safety. These results highlight the intrinsic stability of sodium nickel chloride chemistry, which avoids the flammable electrolytes and runaway risks common in lithium-ion batteries. The ability to withstand extreme electrical and thermal stress demonstrates CERENERGY(R)'s robustness and confirms its suitability for safe, largescale deployment in grid, renewable, and industrial energy storage applications. This was achieved over 3 cycles with 1.8 Full Charge Equivalent (FCE) into 22 hours.

BATTERY PACK ABS60 (60 kWh) PROTOTYPE

The first ABS60 battery pack prototype has been successfully validated under real-world operating conditions, marking a major step forward in product readiness. Testing included diverse load profiles,

continuous discharges at 25 A (equivalent to C-rate of C/4 (discharges in 4 hours), or one-quarter of the pack's rated capacity per hour) at 80% depth of discharge (DoD), short-duration high-current pulses up to 50 A, and carefully controlled thermal variations.

The pack consistently demonstrated stable performance, achieving ~88% round-trip efficiency while maintaining reliable thermal management. Efficiency refers to the proportion of input energy that can be retrieved during operation-a critical measure of economic viability for large-scale storage. Over more than 110 cycles, results showed no observable capacity fading and only a slight increase in internal resistance. Capacity fading refers to the gradual decline in usable energy over repeated cycles, while internal resistance influences power delivery and heat generation.

The absence of meaningful degradation confirms the durability and electrochemical stability of the ABS60 design. These outcomes are highly significant as they demonstrate that the pack can withstand real-world duty cycles while retaining performance and efficiency, translating into longer service life, fewer replacements, and lower total cost of ownership.

For grid operators and renewable integration projects, this combination of robust cycling capability, efficiency, and thermal stability underscores the ABS60's commercial readiness and competitive advantage in the stationary energy storage market.

These results are a strong confirmation of CERENERGY(R)'s technological leadership and a clear signal of the technology's competitiveness and robustness for future applications in energy storage and industrial markets.

Group Managing Director, Iggy Tan said "These results confirm CERENERGY(R)'s robustness and readiness for market adoption. Demonstrating long cycle life, high efficiency, and unmatched safety, we are now strongly positioned to deliver a competitive and sustainable alternative for grid and industrial energy storage."
