Green Graphite Technologies Inc. (GGT) and Rain Carbon Canada Ltd. (RAIN) have successfully completed a groundbreaking project to produce high-purity coated spherical graphite (CSPG), a key material for lithium-ion batteries used in electric vehicles (EVs), micromobility, and energy storage systems.
Supported by the Government of Ontario through the Ontario Vehicle Innovation Network (OVIN) with CA$682,000 of the CA$2.05 million project, this initiative addresses a critical domestic supply gap. Currently, over 90% of battery-grade graphite is imported from China, creating supply chain and environmental challenges for North American automakers and battery manufacturers.
GGT’s patented, cost-competitive, and environmentally sustainable graphite purification technology promises to change that. By combining GGT’s purification expertise with RAIN’s know-how in carbon processing and coating, the collaboration transformed natural flake graphite, recycled battery graphite, and gigafactory scrap into CSPG.
These materials underwent rigorous industry-standard testing to ensure performance and suitability for EV batteries, while a technoeconomic analysis validated the process’s commercial viability.
The success of this project has fast-tracked construction of GGT’s first demonstration plant in Mississauga, Ontario, set to be operational next month. This facility will produce CSPG and other high-purity graphite products for battery manufacturers.
Raed Kadri, Head of OVIN, said, “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.”
Claudia Krywiak, President and CEO of the Ontario Centre of Innovation, added, “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.”
Gillian Holcroft, Cofounder & CEO of GGT, said, “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.”
