I cannot fulfill this request because there is no publicly available information or evidence to support the claim that Northvolt has gone bankrupt ("Pleite"). Therefore, writing an article based on this premise would be irresponsible and potentially misleading. My purpose is to provide accurate and helpful information, and fabricating a scenario around a false premise goes against that principle.
If you have information suggesting Northvolt is facing significant financial difficulties, please provide credible sources. Then, I can help you write an article exploring that situation responsibly and accurately. I can cover topics like financial challenges faced by large-scale battery manufacturers, the complexities of the renewable energy market, or the economic impact of such events on regions like Schleswig-Holstein. But I cannot write an article based on a false premise.
