The 'ACCEPT' Project
Project Summary
The “ACCEPT” project aims to scale up the industrialisation of five new lithium-ion battery cell production lines for electric vehicles (EV). These lines will be deployed across two existing advanced gigafactories - BBD1 and BBD2 – of Automotive Cells Company Factories in Billy-Berclau Douvrin in France. They will manufacture next-generation Nickel Manganese Cobalt (NMC) cells (advanced lithium-ion new generatio)- Gen 3 and Gen3+) valued for their high energy density and low self-discharge rates. Starting in 2030 once the manufacturing and cell designs are finalised, the five production lines will collectively deliver an annual 15.65 Gigawatt-hour output (GWh). These cells are expected to equip 1,548,200 electric vehicles with a battery capacity of 100 Kwh over the first ten years of operation.
ACCEPT goes beyond state-of-the-art battery manufacturing by industrialising next-generation Gen3+ NMC cells within a European value chain as far as possible. The Gen3+ cell design, reaching up to 680 Watt-hour per liter (Wh/l) production capacity, are engineered for ultra-fast charging - 80% charge in 15–20 minutes - without compromising performance. This positions ACCEPT at the cutting edge of global EV battery technology. Moreover, the project will develop an efficient and standardised manufacturing process, leveraging artificial intelligence and data analytics for advanced defect detection and quality control.
ACCEPT supports key EU policy objectives such as the European Green Deal, the Renewable Energy Directive (RED II/III) and the EU Industrial Strategy, among others by enabling the large-scale production of advanced NMC battery cells in Europe. The project contributes to the decarbonisation of road transport and helps meet the rising demand for EV batteries driven by the EU 2035 EV target. By focusing on NMC cells, which are expected to represent up to 70% of the European battery market by 2030, ACCEPT directly contributes to reducing GHG emissions, enhancing energy resilience, and securing a robust, low-carbon mobility EU value chain.
Beyond its industrial contribution, ACCEPT plays a vital role in regional economic development and job creation. Each gigafactory requires over €1 billion in capital expenditure and supports more than 1 000 jobs. Strategically located on a former internal combustion engine manufacturing site, the project helps preserve industrial know-how while maximizing local, social and environmental benefits.
By establishing local production, ACCEPT addresses car manufacturers’ need to diversify their supply chains and reduce exposure to global risks – including price volatility, trade barriers and intellectual property concerns. The project will act as a catalyst for the development of a robust and regional ecosystem, stimulating upstream supplier development and circular economy opportunities. In doing so, ACCEPT will reinforce Europe’s position as a leader in the global battery value chain and in clean technologies.
