The town of Flintbek is not somewhere you would expect to find one of Europe's more credible answers to Chinese battery dominance. It is a quiet commuter settlement south of Kiel, better known for light industry than deep tech.
But tucked inside a climate-controlled production hall there, a company called UniverCell has spent six years learning how to make battery cells the hard way, by controlling every step of the process themselves.
This week the company announced a €30 million Series B, co-led by the DeepTech & Climate Fonds (DTCF), the process technology firm IKA, and industrial measurement group WIKA, with the European Innovation Council Fund also participating.
The capital will go towards expanding production capacity and advancing what the company considers its key competitive asset: a proprietary industrial dry-coating process for electrodes.

The timing is striking. Europe's large-scale battery ambitions have, to put it charitably, had a difficult few years.
Northvolt filed for bankruptcy protection. Porsche shuttered its Cellforce division. The Stellantis-backed Automotive Cell Company paused gigafactory construction.
According to the International Energy Agency, China manufactures more than 80 per cent of the world's batteries, and European pack prices remain roughly 35 per cent above Chinese levels.
Against that backdrop, raising €30 million for a 82-person battery startup in Schleswig-Holstein looks either quixotic or quietly shrewd, depending on what you believe about where Europe can still compete.
Not a commodity play
UniverCell does not make cells for electric vehicles. Co-founders Dr Stefan Permien and Marius Strack, who established the company in 2019, have deliberately positioned it in markets where precision and supply-chain certainty matter more than cost per kilowatt-hour.
Like satellites and space systems, critical care medical devices, and other specialist applications where sourcing batteries from Shenzhen is not always an option.
The factory in Flintbek, which the company describes as a gigafactory, with capacity ready to scale beyond 1.5 gigawatt-hours, produces 21700 cylindrical cells alongside a range of custom electrodes.
All anodes and cathodes are developed and manufactured in-house, a decision that makes the operation more complex and capital-intensive than outsourcing, but which Permien argues pays off in consistency.
“At the heart of every high-performance battery is a production process you truly control,” he said. “Our focus has always been on industrial execution and scalable manufacturing in Europe.”
That in-house logic extends to formation, the electrochemical conditioning step that is, as the company puts it, “the central performance driver of lithium-ion batteries.”
It is unglamorous, painstaking work, and most manufacturers are happy to delegate it. UniverCell has not.
The dry-coating argument
The technology claim at the centre of this round is dry electrode coating, a manufacturing approach that dispenses with the solvent-based slurry process that has defined battery electrode production for decades.
In conventional wet coating, active electrode materials are mixed into a liquid, spread across metal foil, and then baked in long ovens to evaporate the solvent (typically NMP, a chemical that requires careful handling).
The process works, but it is energy-hungry, chemically intensive, and requires substantial factory space.
Dry coating skips the liquid stage entirely, bonding materials in powder form under heat and pressure. The energy savings are meaningful, industry analyses consistently point to reductions of 30 to 40 per cent, and the factory footprint can shrink by up to 60 per cent compared with wet-process lines, according to research UniverCell has cited from its own development programmes.
The resulting electrodes also show improved microstructure, which translates to better energy density, faster charging, and longer cycle life.
Strack was direct about what is at stake: “Dry coating allows us to combine performance, cost efficiency, and sustainability at an industrial scale. This is increasingly critical as regulatory and environmental requirements continue to rise.”
Why these investors, why now
The investor composition is worth unpacking. The DTCF, funded by Germany's Future Fund and the ERP Special Fund, was set up in 2023 specifically to back deep-tech and climate-tech companies with long development cycles, the kind of patient capital that European battery startups have historically struggled to access.
It invests up to €30 million per company, which means UniverCell is at the ceiling of what DTCF can deploy in a single business. The fund has previously backed battery recycling firm Cylib and logistics automation company Fernride.
Dr Elisabeth Schrey, Venture Partner at DTCF, did not shy away from the competitive stakes. “The European battery sector is in a critical situation with pressure from Chinese joint ventures,” she said. “
At the same time, electrification in high-performance applications shows a promising opportunity to create a local champion and secure independent supply chains.”
Svetoslava Georgieva, Chair of the EIC Fund Board, framed the investment in institutional terms: UniverCell, she said, “combines strong technological differentiation with clear industrial relevance in one of Europe's most strategic value chains.”
The narrower bet
What UniverCell is attempting is not a frontal challenge to CATL or BYD. It is a narrower wager: that durable demand exists for premium, custom-made European cells in applications, space, medical, defence-adjacent, where Asian supply chains are structurally less competitive or less trusted. That market exists.
Whether it is large enough to sustain an industrial-scale manufacturer in Northern Germany, with the costs that entails, is the open question that €30 million now gives the company the runway to answer.
Europe has been here before with other technologies, making the same arguments about specialisation and sovereignty and supply-chain resilience, then watching the economics eventually erode the rationale. UniverCell's founders have clearly thought about this.
The company has been deliberately building industrial capabilities, formation, electrode production, cell assembly, that would be difficult to replicate quickly, rather than accumulating IP that a larger player could simply licence around.
Whether that is enough, in batteries, at this moment, remains to be seen. But the architecture of the bet is at least coherent.
