RapidPulse^TM Processing Technology

Transforming the Future of Battery-Grade Graphite

InVert Graphite has signed a binding agreement to acquire RapidGraphite Pty Ltd, a technology business spun out of Curtin University’s globally renowned Carbon Group. This acquisition secures an exclusive worldwide license for the proprietary RapidPulse™ catalytic graphitisation process.

For InVert Graphite, this is a transformational milestone. It evolves the company from a critical minerals explorer into a vertically integrated graphite business, securing a direct, non-acid downstream pathway to produce battery-grade anode material for Western supply chains.

Technology Background

The conventional production of industrial-grade graphite is highly energy-intensive and environmentally taxing. Traditional Acheson furnaces can take up to 30 days of continuous heating to achieve graphitisation, followed by capital-intensive and hazardous acid-purification steps (typically using hydrofluoric acid).

Developed by researchers at Curtin University, the RapidPulse™ process shows potential to disrupt this legacy supply chain. Utilising a proprietary catalyst blend and advanced furnace techniques, RapidPulse™ experimentation has demonstrated that it can reach graphitisation temperatures near 3,000°C to convert carbon feedstocks into roughly 99% pure graphite in a matter of seconds. Crucially, this would eliminate the need for toxic acid-washing, drastically reducing both the environmental footprint and energy consumption of graphite manufacturing.

Morogoro Test Work & Potential Uses

The RapidPulse™ technology could, if proven at commercial scale, provide InVert with immense optionality for clean-tech battery supply chains:

• Morogoro Test Work: RapidPulse™ test work on Morogoro graphite samples demonstrated materially improved crystallinity. Fine grained material of <106µm and a purity of 97.5% TGC was processed through the RapidPulse™ heat treatment to provide non-acid purification to approximately 99%. The processed graphite sample had an initial degree of graphitisation of 90.7% and post heat treatment had an increased graphitisation degree of 98.8%.
• Sustainable Synthetic Graphite: Beyond natural mined graphite, RapidPulse™ shows promise to possess the unique capability to convert sustainable, abundant biomass (such as woodchips or leaf litter) directly into synthetic battery-grade graphite.

The Innovators: Curtin University Carbon Group

The RapidPulse™ technology is the result of years of blue-sky research and materials science innovation driven by the Curtin Carbon Group. To ensure seamless commercialisation, InVert Graphite is proud to integrate the founding scientific talent directly into our operations.

Dr Jason Fogg

Background: Dr Jason Fogg is a materials scientist, researcher at the Curtin Carbon Group, and the co-developer of the RapidPulse™ technology. He specialises in molecular dynamics and conducting ultra-high temperature experiments up to 3,000°C.

Role at InVert: Dr Fogg innovated the custom furnace techniques used to study advanced carbon materials for decarbonisation. He will lead the commercialisation of the RapidPulse™ technology, ensuring the scientific breakthrough successfully scales into industrial-scale production.

Next Steps toward Commercialisation

Following completion of the deal, we will integrate RapidPulse™ into InVert Graphite’s broader corporate strategy, with our focus squarely on scaling the technology from the laboratory to commercial viability. Our high-level pathway includes:

• Scale-Up Testing: Advancing the technology through pre-pilot and pilot-scale battery testing by utilising larger furnace facilities.
• Milestone Execution: Producing consistent, larger-scale batches of synthetic and natural graphite at targeted micron sizes (d50) and purity levels.
• Flowsheet Integration: Continuing integration studies to link Morogoro’s extracted feedstock directly into the RapidPulse™ commercialisation pipeline.
• Industry Qualification: Progressing the technology readiness level to meet the strict qualification standards required by global battery and original equipment manufacturers (OEMs).
