UP Catalyst, a European deep-tech company based in Maardu, Estonia, has achieved a significant milestone in independent testing of its carbon nanotubes (CNTs) derived from CO₂.
The results confirm that these sustainable carbon nanotubes outperform fossil-based benchmarks, offering a viable alternative for next-generation batteries and advanced applications.
An external laboratory verified that UP Catalyst’s CNTs deliver 65% lower power resistivity compared to commercial reference materials. Further testing by a European battery cell manufacturer showed that this enhanced conductivity translates into improved capacity retention under fast-charging conditions. Cells incorporating UP Catalyst’s multi-walled CNTs retained equal or greater capacity at 1C compared to the 0.1C baseline (10-hour charge) and demonstrated up to 10% higher retention under 2C conditions.
This means that batteries using UP Catalyst’s carbon nanotubes can charge in 30 minutes while maintaining high energy storage – supporting both fast-charging and high-performance use cases.
“These results prove that our CO₂-based CNTs are not only sustainable but also deliver outstanding electrochemical performance in real-world testing scenarios,” says Dr Sebastian Pohlmann, CTO of UP Catalyst. “Achieving both lower resistivity and higher fast-charge capability is critical for enabling high-performance lithium-ion batteries.”
With validation from independent partners, UP Catalyst is now expanding testing with industry stakeholders.
“The confirmation from independent testing partners validates our technology, and we now invite more formulators, OEMs and battery cell manufacturers to test our CNTs in their own applications,” says Florian Wunsch, CCO of UP Catalyst.
