Calumix is a nanotechnology company in London, Ontario. Our platform coating technology is the result of decades of R&D inside 3M. We leverage our technology in multiple markets, including Li-ion batteries. We produce advanced current collectors for lithium-ion batteries that are a drop-in solution that improves rate performance and calendar life — while simplifying production and minimizing stack height. North American cell makers focused on high-impact applications, where performance and reliability are non-negotiable, should get in touch.
Advanced Aluminum Current Collector: 20nm that can make a world of difference.
Battery Grade Aluminum Current Collectors: No minimum volumes, <650mm width, origin of your preference.
Tailored Toll Coating Services: You provide the substrate, and we’ll do the rest.

Calumix Technologies is excited to be a recipient of a $4,545,000 investment from Natural Resources Canada. This funding will be used to scale our innovative coating platform for battery current collectors, a technology that enables higher energy density and a lower environmental impact. This support is a major milestone in our mission to strengthen Canada's battery industry.
Canada Advances Battery Innovation with Made-in-Canada Technology - Canada.caCalumix Technologies is proud to receive over $65,000 in new funding from the National Research Council of Canada's Industrial Research Assistance Program (NRC IRAP). This contribution supports the development of our "Carbon Coater Data Pipeline," a project to build the digital infrastructure to capture and analyze real-time data from our proprietary coating process and leverage AI tools to enhance our quality control, boost production efficiency, and ensure the highest product consistency. We thank NRC IRAP for their continued partnership in scaling our innovative battery technology.
Grants and ContributionsWe are excited to announce that Calumix has officially moved into a new, larger facility in London, Ontario! This strategic move doubles our operational footprint, providing the critical space needed to support our ongoing scale-up efforts. The expanded headquarters will house advanced manufacturing equipment and enhanced R&D labs, significantly boosting our capacity to produce our proprietary coated current collectors for the battery industry. This expansion is a key milestone in our growth journey, enabling us to meet increasing customer demand and accelerate the future of battery technology. We're energized for this next chapter!
International investors came together to bolster Calumix, and kick off 2025. In what was a challenging year for seed stage VC deals globally, Calumix turned to solo investors to keep scale up ambitions plans on track.
Supported by Next Generation Manufacturing Canada (NGen), Calumix is partnering with Green Graphite Technologies (GGT) in a $3.4M project to strengthen Canada's EV battery supply chain. This collaboration integrates GGT's sustainable, high-purity graphite into our proprietary carbon-coated current collectors. Together, we are scaling two critical, Canadian-made technologies needed to build a cleaner and more affordable North American transportation sector.
2024-09-23-Green-Graphite-Technologies-Secures-816k-Funding-with-NGen.pdfNGen_Annual-Report-25.pdfWe are thrilled to announce that Calumix Technologies has successfully graduated from the prestigious Creative Destruction Lab (CDL-Toronto) program, completing the intensive Matter stream in the summer of 2024. CDL is a renowned, objectives-based program for massively scalable, science-based companies. Our participation provided us with invaluable mentorship from world-class entrepreneurs and scientists, helping us to sharpen our business objectives and accelerate our technological and commercial milestones. This achievement marks a significant validation of our advanced battery coating technology and our mission to power a sustainable future. We are proud to be a CDL graduate of 2023/2024 cohort and are excited to build on the powerful momentum gained through the program.
