Currently, around 80 % of global battery production capacity is in Asia, with China alone accounting for 69 %, the US for about 15 % and the EU for under 4 %. This situation is unsustainable in the longer term: importing batteries from China significantly increases the carbon footprint of electric vehicles. Moreover, since batteries account for about 40 % of the cost of an electric car, the EU risks jeopardising a large proportion of the value-added part of the production chain and the technological knowledge that can be obtained from it. Developing an EU battery industry offers a solution to this situation and should also help to counter some of the inevitable job losses due to the shift from the traditional combustion engine. Remarkable economic opportunities are possible: the EU market potential could be as high as €250 billion annually from 2025 onwards. Accordingly, EU car manufacturers are progressively widening their range of electric vehicles. The accelerating transition to clean energy means that the demand for batteries is likely to skyrocket. Another inevitable trend is that electric vehicles will have an increasing share in the car market in the coming decades (see Figure 3). Cars based on an electric battery will progressively account for the majority of new cars, with plug-in hybrids phased out as technology based on pure electrics becomes cheaper. However, battery cell manufacturing is an investment-intensive industry at present, necessitating massive volumes and highly automated manufacturing processes.
