Chinese firms dominate battery production. Europe has made significant investments in the battery industry in recent years, but some companies, including Sweden's Northvolt and Norway's Morrow, have filed for bankruptcy, raising concerns about the continent's ability to keep pace with technological advancements. As transport and industry shift from fossil fuels to electricity, the demand for batteries is expected to grow. However, the lengthy process of bringing new products to market and intense competition, particularly from China, pose substantial risks.
Some investors and researchers are exploring innovations at the nanoscale. Christian Rood, CEO of Dutch tech firm LeydenJar, highlights the potential of using plasma deposition to create a lighter, more efficient anode for batteries. This method allows for the production of ultra-thin pure silicon foil, which resists cracking and enhances battery life, charging speed, and energy density by up to 50%.
LeydenJar plans to begin commercial-scale production by the end of 2026, following a decade of development. Rood emphasizes the importance of collaboration between semiconductor technology and battery production, noting that this synergy can provide a competitive advantage in the market.
Similarly, Powall, a start-up in Delft, is working on commercial-scale equipment for nanocoating battery materials. CEO Roderik Colen explains that their technology can slow down battery degradation and enhance performance through precise coatings applied at the nanoscale.
Both LeydenJar and Powall are not manufacturing entire batteries but are instead focused on improving specific components. Rood believes that their innovations can strengthen Europe's position in the global battery supply chain, similar to how ASML has established itself in the semiconductor industry.
Alexander Brown, a senior analyst at the Mercator Institute for China Studies, acknowledges the benefits of having advanced technological components of the supply chain in Europe. However, he warns that China is actively working to develop local alternatives and reduce its reliance on foreign technologies.
Rood notes that while there is funding available in Europe, the risk appetite differs from that in Asia and the US, making it challenging for companies to secure financing. He mentions the need for diverse funding sources, including government grants and investments from the European Investment Bank.
Colen asserts that Europe has the potential to be an innovation leader in battery technology, provided there is a willingness to embrace risk. He suggests that Europe's strategy may not lie in constructing large battery factories but rather in making small, impactful innovations in the industry.
