Volkswagen and Swedish green battery specialist Northvolt have formed a European battery consortium that they hope will accelerate research in a key technology for electric vehicles.

The German carmaker said the European Battery Union (EBU), which includes several other regional partners, will focus on the entire battery value stream, from raw materials to cell technology to recycling.

“The prime objective is to accumulate much broader know-how on battery cell production,” VW said in a press release.

European automakers are worried that, as EV sales take off, their dependence on Asian battery cell producers will increase to the point where their profitability will suffer.

The joint research activities are to start at the beginning of 2020.
