Skeleton Technologies has officially inaugurated its SuperBattery factory in Varkaus, Finland, following a 50 million-euro investment in the facility.
This new site is Europe’s first to manufacture high-power batteries specifically for AI data centers, and the first globally to industrialize backup power systems for mission-critical computing and emerging sectors such as nuclear fusion.
By bringing advanced battery production to Finland, Skeleton aims to strengthen European energy resilience and technological sovereignty. Localizing manufacturing supports the expansion of AI infrastructure, enhances mobility solutions, stabilizes electrical grids, and reduces dependence on international supply chains.
“AI, mobility, and the grid of the future all require extreme power, reliability, and sustainability,” said Taavi Madiberk, CEO and co-founder of Skeleton Technologies. “Our Varkaus factory is a cornerstone for sovereign European AI infrastructure. Elon Musk has said batteries are key for training AI models and he is right. We need to push the performance globally while ensuring that the digital revolution is powered responsibly and independently.”
The factory occupies a site originally owned by European Batteries Oy, which pioneered lithium iron phosphate batteries in Europe. Skeleton’s investment revives this historic center of battery innovation, reenergizing the local battery ecosystem and bolstering Eastern Finland’s economy.
“I have been following Skeleton Technologies since its creation in 2009. Their technical expertise is outstanding, and the opening of the new Varkaus factory represents a major boost for Finland’s innovative battery value chain. It is also very positive news for the economy of Eastern Finland,” says Lassi Noponen, Director General of Business Finland.
Skeleton’s SuperBattery cells leverage NBXCELER™ niobium oxides supplied by CBMM, enhancing safety, performance, and cycle life. These niobium-based materials enable faster charging, greater durability, and higher reliability for demanding AI and industrial applications.
“Niobium plays a key role in shaping a more sustainable future,” said Ricardo Lima, CEO of CBMM. “Our partnership with Skeleton demonstrates how Niobium can make AI infrastructure safer, longer lasting, and more efficient.”
The new factory currently employs over 65 people in Finland and is expected to expand to more than 200 employees by the end of 2029. It will deliver one gigawatt of battery power capacity for AI data centers, grid stabilization, mobility, and defense applications.
