About Us

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.

Offerings

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.
