European Nanotech Startups Seek Micro-Scale Breakthroughs in Battery Race
Following high-profile bankruptcies of Sweden's Northvolt and Norway's Morrow, European investors and researchers are pivoting toward nanotechnology to secure a position in the competitive global battery market. Dominance by Chinese manufacturers and lengthy product development cycles have highlighted the financial risks of building massive battery cell gigafactories across the continent.

Semiconductor Crossover in Eindhoven and Delft
Startups in the Netherlands are adapting precision methods from the semiconductor chip industry to solve critical material bottlenecks. LeydenJar, based in Eindhoven near chip machinery giant ASML, utilizes plasma deposition to produce ultra-thin pure silicon foil anodes. While silicon offers high capacity, it traditionally cracks when expanding during charge cycles; LeydenJar's layered structure prevents structural degradation. Sources: feeds.bbci.co.uk.
LeydenJar's pure silicon foil anode technology increases battery energy density by up to 50% while improving charging speed. — according to feeds.bbci.co.uk, as reported by feeds.bbci.co.uk.
According to feeds.bbci.co.uk, Christian Rood, Chief executive of LeydenJar said: “If you can make this work, it touches so many industries [but] it's a risky business”.
LeydenJar plans to begin commercial-scale production by the end of 2026 after ten years of deep tech development. Similarly, Delft-based startup Powall uses atomic layer deposition—a gas-reaction chemical process derived from chipmaking—to coat microscopic powder granules, slowing down battery degradation caused by repeated cycling.

According to feeds.bbci.co.uk, Roderik Colen, CEO of Powall said: “Your battery works less well than before after using it thousands of times – that degrading or aging can be slowed down when you're using a nanocoating”.
Rather than constructing complete battery cells, both LeydenJar and Powall focus on critical high-margin supply chain components and maintain commercial ties with Asian manufacturing partners. Analysts at the Mercator Institute for China Studies note that securing specialized advanced tech segments offers Europe a viable high-margin foothold in global supply chains.
