BERLIN (Reuters) - Volkswagen and a technology partner have mastered a battery manufacturing process called dry coating which if scaled up could cut the cost of cell production by hundreds of millions of euros a year, its battery chief said on Friday.

The carmaker, which is working with printing press manufacturer Koenig & Bauer AG on the technology, said the two companies are the first to perfect the procedure for both the positive and negative electrode.
