1414 Degrees (ASX: 14D) Integration of SiNTL and SiPHyR Technologies
1414 Degrees Limited (ASX:14D)
Highlights
• Integration of 1414 Degrees’ SiNTL and SiPHyR technologies could deliver a single-step pathway to highperformance graphitic anode material for lithium-ion batteries
• Combining SiNTL aluminium-coated silicon nanoparticles with carbon from SiPHyR reactors could transform a hydrogen by-product into a high-value battery material while reducing production costs
• The silicon-anode battery market is forecast to grow from USD $536.5 million in 2025 to more than USD $20.8 billion by 2034
• Collaboration with the George Washington University advancing OEM-ready testing of SiNTL–SiPHyR anodes, targeting 500 mAh/g within 3 months and 600 mAh/g within 12 months
1414 Degrees Ltd (ASX: 14D) ("1414 Degrees" or the "Company") is pleased to report significant product potential from the combination of its SINTL™ and SiPHyR® technologies to produce high performance graphitic anode material for next-generation lithium-ion batteries.
The Company’s collaborators at the George Washington University (GW) have advised the SiNTL aluminiumcoated silicon nanoparticle process could be adapted to manufacture carbon-silicon composites in a single step, producing a higher value material.
This would be a significant advance over current technologies that use crystalline silicon which must be coated in protective layers in a separate step, then mixed with graphite. By contrast, combining the SiNTL process with carbon from the 1414 Degrees’ SiPHyR methane-pyrolysis reactors could deliver a streamlined, one-step pathway to a premium anode material, transforming a co-product of hydrogen production into a higher-value battery material. This integrated approach may also lower production costs by eliminating multiple coating and mixing steps typical of conventional processes.
Integrating these two proprietary silicon technologies would allow the Company to control both the intellectual property and supply chain across this emerging value chain.
The global silicon-anode battery market is forecast to grow from USD $536.5 million in 2025 to more than USD $20.8 billion by 2034, underscoring the potential for technologies that improve performance, scalability and cost-effectiveness in this sector.
As a next step, the Company will focus on producing the combined SiNTL–SiPHyR anode materials for testing by battery Original Equipment Manufacturers (OEM). Laboratory facilities at the George Washington University are being upgraded to accelerate development and testing. Additional battery test channels will be established to increase the number of anode cells that can be cycled up to 1000 times. Successive trials will aim to increase silicon nanoparticle content, targeting properties of approximately 500 mAh/g (graphite/Si composite) within 3 months and 600 mAh/g within 12 months.
Strategic Context
With the acquisition of the SiNTL technology license 1414 Degrees now holds a suite of silicon-based energy and materials technologies capable of building a downstream value chain, with SiBrick® as the core enabler.
• SiBrick stores renewable electricity as high-temperature heat, providing the thermal backbone for both SiBox and SiPHyR systems
• SiPHyR uses heat from SiBrick to convert natural gas into low-emission hydrogen and solid carbon
• SiNTL nanotechnology technology enables higher silicon content in battery anodes, increasing energy capacity. Carbon from SiPHyR can be combined with SiNTL silicon nanoparticles to produce high-performance anodes
• SiBox® uses SiBrick to capture low-cost electricity and outputs clean, controllable heat to replace fossil-fuel combustion in industrial processes – including, potential use in pre-processing or sintering SiNTL anode material at over 2,000 °C
The integration of these complementary technologies positions 1414 Degrees to explore multiple revenue pathways across the silicon energy ecosystem, from renewable heat and clean hydrogen to advanced battery materials.
