A single battery factory rising along France’s northern coast now carries the weight of Europe’s entire solid-state ambitions, yet it arrives years behind schedule and certified to Chinese standards. That gap underscores how thoroughly Beijing has seized control of the next generation of electric vehicle power.
The timing matters because China’s Ministry of Industry and Information Technology, working with six other government bodies, unveiled a five-year roadmap on 28 September targeting 2030 for initial large-scale application of all-solid-state batteries. The plan spans 2026 to 2030 and also pushes lithium cells capable of 15,000 charge cycles. Officials conceded persistent weaknesses in innovation alongside troubling supply-demand imbalances.
Meanwhile, the industry’s biggest player sounds far less optimistic. Robin Zeng, chairman of CATL, rated all-solid-state technology at four out of nine in June, with nine representing production-ready status. He dismissed the prospect of equipping a million vehicles before 2030 as highly improbable. CATL plans limited output starting in 2027.
South Korean manufacturer LG Energy Solution expects solid-state cells to reach smartphones a full decade before electric vehicles. Its North America chief points to large-format cells as the core manufacturing hurdle.
ProLogium already produces 6,000 packs annually in Taiwan, roughly half a gigawatt hour, achieving 381 Wh/kg under TUV Rheinland testing. That figure runs about 30 percent hotter than cells found in most current EVs. The company secured French subsidies in 2023, obtained permits the following year, and broke ground in February near the Gravelines nuclear station.
The Dunkirk facility starts at 0.8 GWh in 2028, expanding to 12 GWh by 2032. Volkswagen’s PowerCo and Mercedes are separately collaborating with Factorial on proprietary cells.
Chinese and Korean suppliers control 90 percent of Europe’s battery market. Northvolt collapsed after raising $15 billion, leaving Dunkirk as the largest new European cell project since that failure. ProLogium’s cells carry certification against GB/T 43568-2026, the all-solid-state specification Beijing introduced in July.
China captured 70 percent of global electric car output under its previous five-year plan. The new roadmap promises only initial large-scale application, not mass production, and even that remains a target rather than a guarantee.
