Rain Industries Subsidiary Completes Graphite Production Project

Rain Industries Limited, via its wholly owned subsidiary Rain Carbon Canada Inc., has successfully completed a project with Green Graphite Technologies Inc. to advance the production of coated spherical purified graphite. This material is critical in manufacturing lithium-ion batteries for electric vehicles, micromobility, energy storage systems, and other devices. The project was 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.

The financial terms of the project highlight a significant investment in addressing the domestic supply gap for battery-grade graphite. Currently, over 90% of such graphite is sourced from China. The project aims to provide a secured domestic supply with a lower carbon footprint, aligning with North American automobile OEMs and battery cell manufacturers’ needs. The collaboration leverages Green Graphite Technologies’ patented purification technology, which offers a cost-competitive and sustainable solution for producing battery-grade graphite.

Operationally, the project involved transforming three sources of graphite—natural flake graphite, graphite from end-of-life batteries, and graphite from gigafactory production scrap—into coated spherical purified graphite (CSPG). This material, also known as anode active materials, was tested using industry-standard methods to assess its performance and suitability for use in EV batteries. The project also validated the technoeconomic analysis model of the process, ensuring its feasibility and efficiency.

The timeline for the project includes the completion of the first phase of a demonstration plant in Mississauga, Ontario. This plant is expected to be operational early next month, with the goal of producing CSPG and other high-purity graphite products for qualification with battery cell manufacturers. The successful results from this project have enabled Green Graphite Technologies to move forward with this phase, marking a significant milestone in their operational timeline.

The project involved key entities such as Green Graphite Technologies Inc., which provided cutting-edge graphite purification technology, and Rain Carbon Canada Ltd., which contributed its expertise in carbon precursors, carbon material processing, and coating. This collaboration created a synergy that drives innovation and sustainability in the EV sector, addressing critical supply chain gaps.

In the market context, this project is significant as it addresses the reliance on imported battery-grade graphite, particularly from China. By developing a domestic supply chain, the project supports North American manufacturers in reducing their carbon footprint and meeting environmental standards. The Ontario Vehicle Innovation Network’s support underscores the importance of this initiative in reinforcing Ontario’s position as a leader in advanced automotive technology and smart mobility solutions.

Green Graphite Technologies Inc. is focused on commercializing its patented purification technology to produce battery-grade graphite from mined and recycled sources. The company aims to address the urgent need to onshore supply for North American lithium-ion battery manufacturers, offering a cost-effective and sustainable solution.
