Rain Carbon Canada, a subsidiary of Rain Industries Limited, has successfully completed a project with Green Graphite Technologies to advance the production of coated spherical purified graphite. This critical material is essential for lithium-ion batteries used in electric vehicles and energy storage. Supported by a CA$682,000 investment from the Ontario Vehicle Innovation Network, the project aims to address the global supply gap for battery-grade graphite and reduce reliance on imports.
Boosting Domestic Graphite Supply
In a significant move to strengthen the North American battery supply chain, Rain Carbon Canada has finalized a collaborative research project focused on creating high-purity graphite. Currently, over 90% of the global supply of battery-grade graphite originates from China. By developing a domestic production method, the collaboration aims to provide a sustainable, cost-effective alternative for automobile OEMs and battery manufacturers facing critical supply gaps.
Innovation in Material Processing
The collaboration successfully combined Green Graphite Technologies’ proprietary purification process with Rain Carbon’s expertise in carbon precursors and material processing. The project demonstrated the ability to transform three distinct graphite sources—natural flake graphite, end-of-life battery graphite, and gigafactory production scrap—into coated spherical purified graphite (CSPG). Testing confirmed this material is suitable for high-performance electric vehicle applications.
Future Outlook and Plant Launch
The success of this pilot initiative paves the way for the construction of a demonstration plant in Mississauga, Ontario, which is expected to become operational in early Q2 2026. Following this phase, the technology is intended to scale, with plans for a fully commercial CSPG plant by 2029. This transition is expected to lower operating costs by 55% compared to traditional methods while reducing the carbon footprint of anode materials by 82%.
