Most suppliers in this industry do b2b sales. Northvolt would be producing battery cells for use in automotive in large volumes. Volvo is one of their customers. I don't think they do retail sales in small quantities. In general, it seems more common in China for companies to do business with each other via e.g. Alibaba. You can actually order non trivial amounts of raw materials via Alibaba. For example if you search for 1080 steel, you can actually order tons of steel from various suppliers.
