• SiNTL silicon anode achieves 500 mAh/g, matching current commercial benchmarks
• Clear development pathway defined toward 600 mAh/g, 20% higher than existing benchmarks
• Anode testing underway incorporating pristine graphitic carbon from SiPHyR process

1414 Degrees Ltd (ASX: 14D) has announced that its SiNTL silicon anode battery material has achieved its first significant technical performance milestone, months ahead of the commercialisation schedule. The initial composite samples produced under the SiNTL program have achieved specific capacities of 500 mAh/g, meeting the first targeted performance threshold. This result confirms parity with current best-in-class commercial silicon-enhanced anode material alternatives and validates the underlying material design approach. The program is progressing ahead of schedule toward its indicative target of 600 mAh/g within 12 months. A capacity of 600 mAh/g is around 20% higher than typical current commercial benchmarks for silicon-enhanced graphite anodes used in lithium-ion batteries. Achieving 600 mAh/g, while maintaining acceptable stability and manufacturability, would significantly enhance the energy contribution from the anode in standard lithium-ion cell designs. This performance range is commonly seen as a key threshold where silicon-enhanced anodes can provide notable improvements in cell-level energy density without requiring disruptive changes to existing manufacturing processes. In parallel, anode testing is underway incorporating pristine graphitic carbon from the Company's SiPHyR process into the SiNTL synthesis process. This test program aims to validate the quality of SiPHyR carbon output for battery anode applications and may, over time, support additional downstream value opportunities for the SiPHyR hydrogen program including battery anode production and other applications requiring high-quality graphitic carbon.

The SiNTL commercialisation program is underpinned by a repeatable and technically validated development framework that directly links battery performance to material properties across multiple sample formulations. Combined with a low-temperature, scalable synthesis process compatible with existing anode manufacturing infrastructure, this approach supports a clear pathway to production-scale manufacturing without the need for fundamentally new operations.
