AnteoTech (ASX: ADO) — Ultranode™ 95 Silicon Anode Validated in 5 Ah Commercial Pouch Cells at US Battery Innovation Centre With 300+ Cycles and Over 390 Wh/kg
On 21 May 2026, AnteoTech Ltd (ASX: ADO) announced the completion of independent third-party validation of its Ultranode™ 95 high-silicon anode technology in commercial-format 5 Ah Multi-Layer Pouch (MLP) cells at the Battery Innovation Centre (BIC) in Indiana, USA. The MLP cells achieved more than 300 cycles at 70% capacity retention — exceeding the 200-cycle target performance threshold for many defence drone applications — with an enabled specific energy density of more than 390 Wh/kg at battery cell level, representing over 40% higher energy density than traditional graphite anodes. BIC described the Ultranode™ 95 scale-up as "one of the most straightforward scale-up efforts observed by BIC" in its validation report. The next step is the production and testing of 18650 cylindrical cells at BIC, which is currently underway. Multiple potential customers have received Ultranode™ 95 for internal evaluation, and roll-to-roll (R2R) samples produced at BIC are undergoing QA/QC assessment prior to dispatch to US-based drone battery manufacturers.

BIC Validation Results — What Was Tested and What Was Achieved
The Battery Innovation Centre is an independent, non-profit organisation in Indiana that provides third-party battery testing, validation, and pilot-scale cell production. The Ultranode™ 95 validation program commenced in January 2026 and has progressed through three cell formats: coin cells and single-layer pouch (SLP) cells (validated March 2026), and now 5 Ah multi-layer pouch cells.
The MLP cells achieved more than 300 charge-discharge cycles at 70% capacity retention at a 1C/1C rate — meaning the cells were fully charged and discharged once per hour in each direction. The 300-cycle result exceeds the 200-cycle threshold described as the target for many defence drone applications.
The enabled specific energy density of more than 390 Wh/kg compares to approximately 270 Wh/kg for commercial graphite-based cells (such as Tesla 4680-type cells) and approximately 335 Wh/kg for silicon-carbon composite approaches (such as those from Group14 and Sila). The theoretical maximum for pure silicon is approximately 450 Wh/kg at cell level.
BIC stated in its report: the Ultranode™ 95 technology was "successfully scaled up and represented one of the most straightforward scale-up efforts observed by BIC," with "strong confidence in the manufacturability and scalability of the technology."
What is Ultranode™ 95 — How It Differs From Competing Silicon Anodes
Ultranode™ 95 uses elemental micro-silicon (mSi) — a low-cost, widely available form of silicon — rather than the silane-derived silicon-carbon composites used by many competitors. AnteoTech's proprietary formulation binds and stabilises the micro-silicon particles within the anode structure to manage the volume expansion that occurs during lithium absorption, which has historically limited commercial adoption of high-silicon anodes.
The key claimed differentiators are cost and supply chain security. Micro-silicon is available at US$10–25/kg from multiple industrial-scale suppliers, compared to US$80–100/kg (China-sourced) or US$150–200/kg (ex-China) for silane-based silicon-carbon composites. AnteoTech claims this translates to anode-level costs of US$15–40 per Wh/m², compared to US$65–110 for graphite and US$135–340 for Si/C composites.
The 95% active material loading in Ultranode™ 95 anodes is substantially higher than the ~15% silicon content in typical silicon-carbon composite blends, which contributes to the higher energy density.
Commercial Progress — Customer Engagement and JDA Discussions
Multiple potential customers have received Ultranode™ 95 material for internal evaluation, with positive feedback reported. Roll-to-roll (R2R) samples produced at BIC are undergoing QA/QC before dispatch to two US-based drone battery manufacturers with whom AnteoTech is in Joint Development Agreement (JDA) discussions.
AnteoTech is also in discussions with companies supplying drones and drone-related systems into the Australian defence sector regarding a future cell evaluation program using Ultranode™ 95 cylindrical cells.
No binding commercial agreements, JDAs, or customer contracts have been executed. All customer engagements are at the evaluation and discussion stage.
Target Markets — Drones, Defence and Portable Power
The primary target market is drone and UAV batteries, where energy density directly translates to flight time and payload capacity. The global drone battery market is estimated at approximately US$8–9.5 billion annually and forecast to grow at approximately 18% CAGR to approximately US$42 billion by 2034. The US is expected to account for roughly one-third of global demand.
Defence applications are a focus, with the US SkyFoundry Act of 2025 targeting one million domestic drone units annually, and the EU European Drone Defence Initiative creating additional demand. Australia's 2026 National Defence Strategy includes up to A$7 billion allocated to counter-drone capability within the A$425 billion Integrated Investment Program.
A secondary market is soldier-worn systems and portable defence electronics (projected US$10.3 billion by 2030), where battery weight is a critical selection factor.
Market Context
ADO closed at $0.017 on the announcement day, up +30.8% from a previous close of $0.013, with an intraday high of $0.024. The stock pulled back from $0.024 to close at $0.017. The 52-week range spans $0.007 to $0.028. At sub-2-cent prices, the absolute price movement was $0.004.
Risks & Considerations
Pre-revenue technology: AnteoTech has no commercial revenue from Ultranode™ 95. All customer engagements are at the evaluation and discussion stage. No binding JDAs, supply agreements, or customer contracts have been executed.
Validation ≠ commercial deployment: The BIC validation demonstrates manufacturability and performance in a controlled third-party environment. Transitioning from validation to commercial cell manufacturing at scale involves additional engineering, quality, and supply chain challenges that have not been demonstrated.
In-house testing vs BIC results: The 2,000–2,500 mAh/g anode coating capacity is from AnteoTech's in-house testing. BIC reported a first silicon active material discharge capacity of 1,966 mAh/g. The company notes further optimisation is underway to bring in-house results to commercial cell formats.
Cycle life context: The 300 cycles at 70% capacity retention exceeds the stated 200-cycle defence drone target. However, consumer electronics and EV applications typically require 500–1,000+ cycles, and the cycle life performance for these higher-demand applications has not been demonstrated.
Cost claims are modelled: The cost comparison tables use active material costs only and are based on internal assumptions. They are not full cell production costs and may not reflect actual manufacturing economics at commercial scale.
Competitive landscape: The high-silicon anode space is competitive, with well-funded companies including Group14, Sila Nanotechnologies, Enovix, and Amprius pursuing various approaches. Several competitors are further advanced in commercial deployment.
Sub-2-cent stock: ADO trades at sub-2-cent levels with limited liquidity. The $0.004 absolute move represents a 30.8% change, and the intraday range ($0.013 to $0.024) shows significant volatility.
No financial data disclosed: Revenue, cash position, and balance sheet information were not disclosed in this announcement.
