Green Graphite Technologies (GGT), in collaboration with Rain Carbon Canada Ltd, has successfully completed a project to advance the production of coated spherical purified graphite (CSPG), a critical material used in lithium-ion batteries powering electric vehicles, micromobility solutions, and energy storage systems. The initiative was supported by the Ontario Vehicle Innovation Network (OVIN), which contributed CA$682,000 toward the total project value of CA$2.05 million. The project directly addresses a major gap in North America’s battery materials supply chain, where more than 90% of battery-grade graphite is currently sourced from China.
Automotive manufacturers and battery producers across North America are increasingly seeking locally produced graphite that offers both cost competitiveness and a reduced environmental footprint. However, replicating conventional purification methods used overseas has proven economically and environmentally challenging under North American standards.
GGT’s patented purification technology provides a viable alternative. Designed to lower operating costs while significantly reducing emissions, the process enables sustainable, domestic production of battery-grade graphite. By combining GGT’s innovation with Rain Carbon’s expertise in carbon materials and coating technologies, the collaboration has demonstrated a scalable solution for the EV supply chain.
The project successfully converted three graphite sources—natural flake graphite, recycled graphite from end-of-life batteries, and production scrap from gigafactories—into CSPG at pilot scale. These materials were tested using industry-standard methods to confirm their performance in battery applications. A techno-economic model was also validated, reinforcing the commercial feasibility of the process.
Following these results, GGT is proceeding with the first phase of its demonstration plant in Mississauga, Ontario. The facility is expected to begin operations in early 2026 and will focus on producing CSPG for qualification with battery manufacturers.
Industry leaders emphasized the importance of the milestone. Raed Kadri of OVIN highlighted the project as a reflection of Ontario’s commitment to strengthening its role in the global EV supply chain. Claudia Krywiak of the Ontario Centre of Innovation noted that such initiatives help reduce reliance on imports while accelerating locally developed technologies.
GGT’s leadership also underscored the significance of collaboration in closing supply chain gaps and advancing toward commercialization. The company is targeting the launch of its first commercial graphite plant by 2029.
