The EU has made bold commitments to vehicle electrification, aiming for 100% electric vehicle (EV) sales by 2035. Central to this vision is establishing a robust, competitive battery manufacturing industry. But hereโs the problem: many European gigafactories have stumbled, struggling to meet quality standards or collapsing entirely (remember Italvolt and Britishvolt?). Northvolt, once a beacon of hope, is facing challenges, while industry-wide delays and cost overruns put the whole EU progress at risk.
So, whatโs wrong?ย
The Missing Ingredient: Manufacturing Expertise ๐ ๏ธ
The EUโs battery value chain isnโt failing due to a lack of chemistry breakthroughs or innovation in the lab. Itโs manufacturing expertiseโparticularly in scaling productionโthatโs the issue. China, with over 20 years of experience in building and operating gigafactories, has a massive lead. While Europeโs innovators are busy inventing new battery chemistries, they lack the critical know-how to transition from lab-scale innovation to gigawatt-hour-scale production.ย
This gap is whatโs putting the EUโs electrification goals at risk.
The Real Breakdown: Electrode Production vs. Cell Assembly โ๏ธ
Letโs break it down. Battery cell manufacturing involves two main processes: electrode production and cell assembly. Hereโs the kicker: 70-80% of gigafactory capital expenditure (CAPEX) goes into electrode production, which is an electrochemical process requiring advanced machinery and experienced engineers. In contrast, cell assembly is more mechanical, highly automated, and requires less investment.ย
In the traditional gigafactory model, both processes are co-located. But is this really the most efficient or sustainable approach for Europe?
An Alternative Way: The Hub-and-Spoke Model ๐ญ
Hereโs where things get interesting. Instead of replicating the massive, co-located gigafactory model used by Asian manufacturers, the EU could adopt a hub-and-spoke approach. What does that mean?ย
Picture a few specialized electrode foundries spread across Europe, serving multiple, smaller cell manufacturers. These foundries would handle the highly technical, CAPEX-intensive process of electrode production, while cell assembly would be decentralized. The result? More flexibility, lower costs, and a faster path to scaling up production.ย
The Foundry Model: Lessons from Semiconductors ๐ก
Weโve seen this approach work in other industries. In semiconductors, foundries focus on production, while design and innovation come from startups and research institutions. This model allows for faster innovation cycles and more specialization. By applying this approach to battery manufacturing, the EU could become a global leader in electrode production, with startups and research labs driving the design process.
A Proposal: Start Small, Think Big ๐
The proposal? Start by establishing a dedicated electrode foundry somewhere in France, the Netherlands, or another EU battery cluster. This foundry would have a capacity of 1-2 GWh to minimize initial capital outlay while providing a crucial training ground for EU manufacturers. Partnering with experienced players from Asia willing to share their know-how (if you donโt believe that such an animal exists in the wild - drop me a note) could accelerate the learning curve, helping Europe develop the manufacturing skills it so desperately needs.
Why This Matters ๐ง
By centralizing electrode production, the EU could leapfrog its current challenges, reduce dependency on Asian suppliers, and build a sustainable, competitive battery value chain. This model not only accelerates innovation but also fosters collaboration between startups, gigafactories, and research institutes. Itโs a win-win scenario that could secure Europeโs leadership in battery technology.
The EUโs journey to full electrification may be rocky, but with strategic investments like these, it could chart a new course toward a cleaner, more sustainable future.
