What Calumix does
Calumix is a private nanotechnology company headquartered in London, Ontario, Canada, that commercializes advanced aluminum current collectors for lithium-ion batteries. The company's core technology is a 20nm nano-coating process applied to battery-grade aluminum current collectors, platform-licensed from decades of R&D conducted inside 3M. The hardware product line is engineered as a drop-in replacement for existing foils, with stated functional gains in rate performance, calendar life, and simplified cell production, and maximum widths under 650mm. Production capacity was doubled in July 2025 via a move to a larger London, Ontario facility housing advanced manufacturing equipment and R&D laboratories.
The business operates a dual revenue model: (1) sale of advanced nano-coated aluminum current collectors (and standard battery-grade collectors with no minimum volume) on a unit-pricing basis, and (2) tailored toll coating services in which customers supply substrates and Calumix applies its proprietary coating. Pricing is contact-based for advanced products and toll services, with no minimum volume constraints on the standard battery-grade line. Go-to-market is direct enterprise field sales targeting North American lithium-ion battery cell manufacturers serving high-impact, reliability-sensitive applications; the company's stated markets served are limited to Canada and North America. Distribution channels include a company website with inquiry/sample request capability and a LinkedIn presence, supported by accelerator and conference participation (Creative Destruction Lab Matter Stream, 2023/2024 cohort).
Calumix has begun extending its materials platform beyond batteries, with an NRC IRAP-funded free chlorine sensor project for pool water applications underway since June 2025. The company has raised a March 2025 seed round (international and solo investors) alongside more than CAD $8.3M in cumulative non-dilutive government funding via NGen (CAD $3.4M, with Green Graphite Technologies), NRC IRAP (chlorine sensor and AI data pipeline), and Natural Resources Canada (CAD $4.545M for production scale-up). Headcount is 1–10 and no commercial customers or revenue are publicly disclosed.

Calumix product offering
Product offeringCore offering
Calumix manufactures advanced nano-coated aluminum current collectors for lithium-ion batteries, leveraging a 20nm platform coating technology originally developed through decades of R&D inside 3M. The company also provides tailored toll coating services where customers supply their own substrates and Calumix applies its proprietary coating. Products serve as drop-in solutions designed to improve rate performance, extend calendar life, simplify production, and minimize stack height for North American battery cell manufacturers.
Product overview
Calumix offers a platform of advanced nano-coated current collectors for lithium-ion batteries, consisting of three main product lines. The Advanced Aluminum Current Collector (20nm coating) serves as the flagship offering, while Battery Grade Aluminum Current Collectors provide standard specifications without minimum volumes. Tailored Toll Coating Services allow customers to bring their own substrates for proprietary coating. All offerings leverage Calumix's platform coating technology derived from decades of 3M R&D.

One partnership is on record.
- Green Graphite Technologies (GGT)coreSupported by Next Generation Manufacturing Canada (NGen), Calumix partners with Green Graphite Technologies in a $3.4M project to strengthen Canada's EV battery supply chain. This collaboration integrates GGT's sustainable, high-purity graphite into Calumix's proprietary carbon-coated current collectors. Together, the companies are scaling two critical Canadian-made technologies needed for a cleaner, more affordable North American transportation sector.

Calumix competitors and assessment
Company assessmentDirect peers
- SGL Carbon: SGL Carbon produces carbon-coated aluminum current collectors for lithium-ion batteries, directly overlapping with Calumix's flagship 20nm nano-coated current-collector product. Both companies target performance improvements in rate capability and calendar life at the current-collector layer.
Emerging players
- Nano One Materials: Nano One is a Canadian battery materials company developing advanced cathode and lithium-iron-phosphate materials, sharing Calumix's strategy of building a domestic, sustainably sourced battery materials supply chain. Both are Canadian-headquartered, government-supported, and target North American gigafactories.
- Talga Resources: Talga is developing graphite anode materials and coating technologies for Li-ion batteries, with a focus on high-performance, sustainable inputs. The carbon-coating aspect of its anode technology overlaps conceptually with Calumix's carbon-coated current collector approach.
- Group14 Technologies: Group14 manufactures silicon-based battery anode materials, sitting one layer upstream of current collectors in the cell architecture. The two companies compete for similar North American cell-maker wallet share in next-generation Li-ion performance improvements.
- Echion Technologies: Echion develops niobium-based anode materials for fast-charging Li-ion batteries, targeting commercial cell makers with a drop-in active material. It is comparable to Calumix in being an anode-layer performance upgrade play selling into established cell manufacturers.
- Novonix: Novonix develops battery materials (synthetic graphite anodes) and battery testing technology for North American and global cell makers. Like Calumix, it is positioning around IRA-supported, domestically produced battery materials, though at the anode active material layer rather than the current collector.
- 6K Energy: 6K Energy uses a proprietary plasma-based production process to make battery cathode and anode active materials, targeting North American gigafactories. It is comparable to Calumix as a next-generation battery materials producer competing on process technology and domestic supply.
Broad incumbents
- Resonac (formerly Showa Denko): Resonac is a major Japanese chemicals and materials supplier that produces aluminum current collectors and other battery components at scale for global cell makers. It is the most likely large incumbent competitor to Calumix in coated aluminum current collectors.
- UACJ: UACJ is a major Japanese aluminum manufacturer that supplies battery-grade aluminum foil used as current collectors in Li-ion cells. As a high-volume incumbent in the same physical product category, UACJ represents the cost-competitive incumbent Calumix must displace to scale.
- Sila Nanotechnologies: Sila is a more advanced, well-capitalized battery materials company selling silicon-anode technology into consumer and automotive Li-ion cells. It is comparable to Calumix as a nanomaterials-based battery materials startup selling drop-in performance upgrades to incumbent cell makers.
