How can a successful and sustainable development of a battery industry in Europe succeed? What role do regional value-added structures play in this process and which industries are suitable partners for battery cell manufacturing? The team of the scientific accompanying research of the European technology and innovation support program for battery cell production (Important Project of Common European Interest, IPCEI) got to the bottom of these and other questions on behalf of the German Federal Ministry of Economics and Climate Protection. The study is a practical guide for companies that want to be successful in the battery industry in the long term and are looking for suitable locations or suitable cooperation partners. In addition, the publication provides deep insights into the importance of cluster initiatives for regional value creation.
