BERLIN : 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.In traditional battery manufacturing, materials for the cathode - or positive electrode - and anode - negative electrode - are applied to a carrier foil via a chemical paste mixture that needs to dry, requiring high amounts of energy.
Volkswagen said it has produced several hundred cells with its method on a pilot line and should be ready for industrial production by 2027. Together with scaled-up production and cheaper raw materials, the carmaker hopes the procedure will help bring down cell costs by around 50 per cent, Schmall said.
Its cell plants under construction in Germany, Spain and Canada will still have drying lines but can be retrofitted to remove them at a later date, PowerCo Chief Operating Officer Sebastian Wolf added, freeing up around 15 per cent of factory floor space.
