Can Europe recharge its battery industry?

Europe’s battery sector is trying to claw back ground lost to Chinese giants by focusing on ultra‑small‑scale innovations, a strategy embodied by Dutch firms LeydenJar and Powall. LeydenJar, led by CEO Christian Rood, uses plasma deposition to produce an ultra‑thin pure‑silicon anode foil that resists the cracking that normally plagues silicon‑based batteries, promising up to a 50 % boost in energy density, faster charging and longer life. After a decade of development, the company plans to launch commercial‑scale production in Eindhoven at the end of 2026, leveraging the city’s semiconductor ecosystem to secure patents and supply‑chain advantages that are harder to obtain in the United States or China. Powall, based in Delft, complements this approach by offering atomic‑layer‑deposition equipment that nanocoats battery‑grade powder particles, slowing degradation and enabling the use of higher‑capacity materials while maintaining durability.

The push for nanotechnology reflects Europe’s broader need to re‑establish a foothold in the global battery value chain as transport and industry shift toward electrification. Earlier high‑profile setbacks, such as the bankruptcies of Sweden’s Northvolt and Norway’s Morrow, have heightened concerns that Europe may miss another pivotal technology transition. By targeting components rather than whole cells, firms like LeydenJar and Powall aim to sidestep the massive capital outlays required for full‑battery factories, instead inserting themselves into a niche where European semiconductor expertise can be repurposed. This approach also aligns with the continent’s strategic goal of diversifying supply chains away from China, offering a “critical step” in battery production that mirrors how ASML supplies essential lithography equipment without manufacturing chips itself.

Analysts see these deep‑tech ventures as potential anchors for a more resilient European battery ecosystem. Alexander Brown of the Mercator Institute for China Studies notes that securing even a single segment of the supply chain would be a significant win for Europe. Both LeydenJar and Powall already maintain commercial ties with Asian customers, indicating that their technologies are already market‑relevant. If their nanocoating and silicon‑anode solutions can be scaled successfully, they could provide European automakers and industrial users with locally sourced, high‑performance battery components, reducing dependence on Chinese imports and strengthening the continent’s position in the intensifying global race for battery supremacy.
