Despite previous setbacks and intense competition, particularly from China, European deep tech startups like LeydenJar and Powall are developing nanoscale battery technologies. These innovations aim to improve battery efficiency, lifespan, and charging speed, positioning Europe to secure a high-value niche in the global battery supply chain.
Imagine your phone battery could last much longer and charge super fast! Scientists in Europe are trying to make tiny, tiny parts of batteries, smaller than a speck of dust, using clever tricks from making computer chips. This makes batteries stronger and better, so Europe can help make the best batteries in the world, just like they help make the best chip-making machines.
Analysis
LeydenJar
Dutch tech firm LeydenJar is at the forefront of European efforts to innovate in battery technology, focusing on an almost unimaginably small scale. The company utilizes a technique called plasma deposition to create a lighter, more efficient anode, a crucial component in all batteries. This method allows for the creation of an ultra-thin pure silicon foil, which, unlike conventional silicon, resists cracking despite the material's natural expansion and contraction during battery operation and recharging.
This breakthrough addresses a significant bottleneck in battery performance, enabling a substantial increase in battery life, charging speed, and energy density, reportedly up to 50%. Christian Rood, LeydenJar's chief executive, highlights the invention's stability where pure silicon anodes would typically fail. While commercial-scale production is slated for late 2026, the decade-long development journey underscores the extensive time and investment characteristic of Deep Tech innovations.
Powall
Another Dutch startup, Powall, is contributing to Europe's battery ambitions by developing commercial-scale equipment for nanocoating battery raw materials. Operating at a similarly tiny scale, Powall applies coatings measured in nanometres to individual powder granules, which are themselves micrometre-sized. This technique, known as atomic layer deposition, also originates from the semiconductor industry, showcasing a cross-sectoral transfer of expertise.
Roderik Colen, Powall's CEO, explains that these nanocoatings offer multiple opportunities to enhance battery performance. They can significantly slow down the degrading or aging process that batteries experience after numerous charge cycles. Furthermore, the protective coating enables the commercial viability of exciting new materials that might offer higher capacity or faster charging but typically suffer from poor durability, thus providing a crucial enabling technology for next-generation batteries.
ASML
The European strategy in battery technology, as articulated by industry leaders and analysts, draws a direct parallel to the success of Dutch tech giant ASML in the semiconductor sector. Christian Rood of LeydenJar explicitly states his company's ambition to secure a unique position in the battery supply chain, akin to ASML's role in chip production. ASML does not produce chips itself but focuses on a critical, highly advanced step in their manufacturing, granting it a pivotal "seat at the table" in the global semiconductor industry.
Alexander Brown, a senior analyst at Merics, supports this approach, noting that having a highly advanced, high-margin part of the supply chain based in Europe is "fantastic." This strategy aims to fortify Europe's position in the global battery contest by specializing in cutting-edge components and intellectual property, rather than attempting to compete directly in full battery production against dominant players like China. The ecosystem in Eindhoven, home to ASML, provides a competitive advantage for such crossover innovations.
Key points
- Europe is attempting to gain ground in the battery industry by focusing on nanotechnology.
- Dutch firms LeydenJar and Powall are developing advanced battery components at a nanoscale.
- LeydenJar uses plasma deposition to create pure silicon anodes, significantly increasing battery life and energy density.
- Powall develops nanocoatings to improve the durability and enable new materials for batteries.
- The European strategy draws parallels to the semiconductor industry's success, aiming for a critical niche in the supply chain, similar to ASML's role.
Europe's strategic focus on deep tech and nanotechnology in battery components could establish a high-margin, critical niche in the global supply chain, mirroring ASML's success in semiconductors. This approach fosters innovation, reduces reliance on foreign producers for essential technology, and could lead to a more resilient and advanced European battery industry.
Despite promising innovations, the brutal competition, especially from China, and the inherently long development cycles for deep tech pose significant risks. Europe's past high-profile failures in battery production, such as Northvolt and Morrow, highlight the immense challenge of scaling these advanced technologies commercially against established global players.
