We have surpassed a key performance milestone in our silicon nanoparticle battery materials program, achieving 530 mAh/g specific capacity in laboratory testing.

The result exceeds the previously announced 500 mAh/g target and places us ahead of schedule toward our 600 mAh/g development goal, which would represent around a 20% performance improvement over current commercial silicon-enhanced anode benchmarks.

Testing was conducted at George Washington University under 1414 Degrees’ exclusive global licence for the SiNTL™ silicon nanoparticle technology.

The 530 mAh/g result was achieved under controlled test conditions using a four-hour charge/discharge cycle between 20–80% state of charge.

Graphite, which currently dominates lithium-ion battery anodes, has a theoretical capacity of approximately 372 mAh/g, limiting further gains in battery energy density. Silicon offers significantly higher potential capacity but has historically faced commercial challenges due to expansion during lithium absorption.

The SiNTL process produces aluminium-coated silicon nanoparticles using a low-temperature one-step synthesis method operating between 125–180°C. The coating forms during synthesis and is designed to stabilise silicon’s expansion while maintaining conductivity.

Unlike many competing approaches that rely on chemical vapour deposition using silane gas and specialised infrastructure, the SiNTL process is designed to be compatible with existing lithium-ion battery manufacturing lines, enabling manufacturers to integrate the material without major retooling.

Executive Chairman Dr Kevin Moriarty said the result demonstrates the effectiveness of the technology approach.

“Surpassing the 500 mAh/g milestone ahead of schedule is a meaningful result for the SiNTL program,” he said. “The 530 mAh/g figure demonstrates that our aluminium-coating approach is working as designed under real test conditions and that the pathway to 600 mAh/g is credible.”

There is also a potential future integration between our SiNTL battery material technology and SiPHyR® methane pyrolysis system, which produces solid carbon alongside low-emissions hydrogen.

Combining this carbon with SiNTL silicon nanoparticles could create a streamlined production pathway for silicon-carbon composite anodes, potentially reducing processing steps and manufacturing costs.

Testing continues at George Washington University with ongoing work focused on increasing capacity, validating cycle life and assessing scalability for commercial battery applications.

Industry analysts project the global silicon anode battery market could grow from approximately USD 0.4 billion in 2025 to USD 25.8 billion by 2035, reflecting increasing demand for higher-performance batteries for electric vehicles and energy storage.

1414 Degrees has achieved a major technical milestone in the development of our SiNTL™ silicon anode battery material, reaching 500 mAh/g specific capacity – the program’s first target – months ahead of schedule.

This result aligns with current best-in-class commercial silicon-enhanced anode materials, validating both the SiNTL composite architecture and low-temperature synthesis process. Importantly, we have now established a clear and repeatable development pathway toward 600 mAh/g, a level that would represent an improvement of around 20% over typical current commercial benchmarks.

Reaching this performance range is widely considered a key threshold where silicon-enhanced anodes can deliver meaningful improvements in lithium-ion battery energy density while remain gin compatible with existing manufacturing processes.

Alongside this progress, testing is underway to incorporate pristine graphitic carbon produced via our SiPHyR™ process into the SiNTL synthesis pathway. Over time, this work may support additional downstream value opportunities across our silicon platform, including battery anode production and other high-value carbon applications.

Chief Technology & Operations Officer Dr Peter Yaron said the milestone reinforces SiNTL’s commercial relevance:
“This result demonstrates that SiNTL is not just a research program — it is a commercial platform in development. As performance improves and scalability is validated, its strategic relevance to battery manufacturers and OEM supply chains becomes increasingly clear.”

The SiNTL program is underpinned by a development framework that directly links battery performance to material properties across multiple formulations. Combined with a scalable, low-temperature synthesis process compatible with existing anode manufacturing infrastructure, this approach supports a clear pathway toward production-scale manufacturing.

We have released our Quarterly 4C Activities and Cashflow Report for the period ended 31 December 2025, marking a quarter of strong momentum across the Aurora Energy Precinct and our portfolio of silicon-based technologies.

During the quarter, we continued to position the Aurora Energy Precinct as a nationally significant, multi-use energy and infrastructure hub, anchored by a 140 MW / 280 MWh Battery Energy Storage System (BESS). Subsequent to quarter end, we achieved a major regulatory milestone with AEMO and ElectraNet accepting the Generator Performance Standards for the Aurora BESS. This represents a material de-risking event and advances the project toward connection to the National Electricity Market.

Aurora also attracted increasing interest from large-scale infrastructure and energy-intensive users, including hyperscale data-centre developers. This interest reinforces our long-held strategy to develop Aurora as a flexible precinct capable of supporting evolving demand from both the energy market and new digital and industrial sectors.

Commercialisation of our Heat-as-a-Service offering continued, with SiBox® and SiBrick® supporting new industrial decarbonisation feasibility assessments. Technical development during the quarter demonstrated improved thermal cycling performance, supporting durability and cost-reduction pathways.

We also commenced active development of our SiNTL™ battery materials program following the acquisition of the exclusive global licence. We are targeting a capacity of 600mAh/g in the first twelve months of the program. In parallel, successful hydrogen and solid carbon production from our SiPHyR® reactors informed the design of a larger prototype, with construction commencing in the current quarter. Integration work between SiPHyR and SiNTL has begun, targeting higher-value carbon–silicon composite battery materials.

Our execution capability was further strengthened with the appointment of Dr Peter Yaron as Chief Technology & Operations Officer, enhancing our ability to deliver across our expanding development and commercial pipeline.

Commenting on the quarter, Executive Chair Dr Kevin Moriarty said the period reflected a strong focus on delivery and progress across our priority initiatives.

We are pleased to announce that the Australian Energy Market Operator (AEMO) has accepted the proposed Generator Performance Standards for the 140 MW Aurora Battery Energy Storage System (BESS), in accordance with the National Electricity Rules.

ElectraNet, South Australia’s transmission network service provider, has also confirmed acceptance of the full Generator Performance Standards package. This acceptance is valid for 12 months, subject to execution of a Transmission Connection Agreement (TCA).

Both AEMO and ElectraNet have advised that connection of the Aurora BESS will not result in an adverse system strength impact on other existing or committed generating systems.

1414 Degrees manages the BESS project and the broader Aurora Renewable Energy Precinct on behalf of SiliconAurora Pty Ltd (SiAu), which holds the Crown Lease over the 15.8-hectare site. To date, SiAu has invested over $3.5 million in generator studies and regulatory approvals to advance the development of the Precinct.

Following this milestone, AEMO has advised that its final due diligence assessment will commence once final technical models and detailed design information are submitted. In parallel, we will progress remaining technical deliverables and work toward finalising the Transmission Connection Agreement, enabling advancement of power purchase agreement (PPA) discussions with customers.

As previously announced, separate negotiations are required with the current sole user of the existing transmission line to enable reclassification of the line as a Dedicated Connection Asset, allowing open access to the National Electricity Market. The Company remains confident that agreement will be reached.

This connection milestone represents the first component of a broader Continuous Energy Hub planned for the Aurora Precinct. As outlined in the our announcement dated 9 January 2026, the site has potential to support future data centre and other developments, subject to commercial arrangements. This potential is underpinned by increasing global investment in AI-driven digital infrastructure and demand for firm, reliable electricity supply.

1414 Degrees Executive Chairman, Dr Kevin Moriarty, said:

“This milestone represents a critical regulatory step forward and allows the Aurora Precinct to move toward commencement in 2026. In addition to revenue from the BESS, it supports broader development opportunities, including data centre potential previously outlined by the Company.”
