Paving the way for Ontario Demonstration Plant Launch.
Hamilton, Ontario, Canada, April 1st, 2026
Green Graphite Technologies Inc. (“GGT”), an emerging graphite manufacturing technology company, in collaboration with Rain Carbon Canada Ltd. (“RAIN”), announced the successful completion of its project to advance the production of coated spherical purified graphite, a critical material in the manufacturing of lithium-ion batteries for electric vehicles (EV), micromobility, energy storage systems and other devices. This project was generously supported by the Government of Ontario through the Ontario Vehicle Innovation Network (OVIN), which contributed CA$682,000 to the total project value of CA$2.05 million.
This project addresses a critical domestic supply gap for battery materials. Currently, over 90% of all battery-grade graphite is sourced from China. North American automobile OEMs and battery cell manufacturers are all seeking a secured, domestic supply of battery-grade graphite with a lower carbon footprint, but at a similar cost. Implementing current purification practices from China in North America while meeting our environmental, health and safety standards is not cost-effective. GGT, with its patented, cost-competitive, highly sustainable graphite purification technology, will enable this domestic supply of battery-grade graphite.
This collaboration brought together GGT’s cutting-edge graphite purification technology and RAIN’s extensive expertise in carbon precursors, carbon material processing and coating, creating a powerful synergy, driving innovation and sustainability in the EV sector. The project involved transforming three sources of graphite at the pilot scale – natural flake graphite, graphite from end-of-life batteries, and graphite from gigafactory production scrap – into coated spherical purified graphite (CSPG), also known as anode active materials. This material was then tested using industry standard methods to assess their performance and suitability for use in EV batteries. The technoeconomic analysis model of the process was also validated as part of this project.
The successful results from this project have enabled GGT to move forward with the construction of the first phase of its demonstration plant, currently being completed in Mississauga, Ontario. It will be operational early next month, with the goal of producing CSPG and other high-purity graphite products for qualification with battery cell manufacturers and others.
“This critical investment by OVIN reflects the province’s strong commitment to accelerating the growth of Ontario companies to power the global supply chain of today and tomorrow with Ontario-made technologies. By tackling gaps in our domestic supply chain head-on, homegrown companies like Green Graphite Technologies are accelerating and powering Ontario’s electric future.”
Raed Kadri, Head of OVIN.
Ontario is building one of the most advanced electric vehicle and battery supply chains in the world, and projects like this demonstrate the strength of our homegrown innovation. By supporting companies like Green Graphite Technologies through the Ontario Vehicle Innovation Network, we are helping develop the critical materials and technologies needed to strengthen domestic supply chains, reduce reliance on global imports, and accelerate the production of made-in-Ontario solutions that will power the future of electric mobility.
Claudia Krywiak, President and CEO of the Ontario Centre of Innovation (OCI).
Our success comes from harnessing home-grown innovation and strong partnerships to close a critical gap in Canada’s EV supply chain. Our collaboration with Rain Carbon proves what is possible as we launch this next demonstration phase, putting us on a clear path to a commercial CSPG plant in 2029. We’re also deeply grateful to OVIN and our stakeholder partners for helping make this milestone possible.

About Green Graphite Technologies Inc.
Green Graphite Technologies Inc. (GGT), headquartered in Montreal, Quebec with pilot operations in Mississauga and Kingston, Ontario, is commercializing its patented purification technology to produce battery-grade graphite from mined and recycled sources to address the urgent need to onshore supply for North American lithium-ion battery manufacturers (i.e. gigafactories). With 55% lower operating costs compared to traditional methods and an 82% reduction in carbon footprint versus China-produced anode active materials, GGT’s technology is poised to enable the cost-effective and sustainable onshoring of midstream processing of this critical mineral. Following successful piloting, GGT will be starting up the first phase of its technology demonstration in early Q2 2026 in Mississauga, Ontario. GGT plans to establish its first commercial lithium-ion battery grade graphite plant operational in 2029.
