Once Norway's Vianode launches production in North America, the deal will run through 2033. The new plant could be in the U.S. or Canada.

The deal, with Norway’s Vianode, is for delivery of a material critical for electric-vehicle batteries, the companies said Wednesday.

General Motors has signed a multi-year, multi-billion dollar agreement for Norway's Vianode to provide the U.S. automaker with synthetic graphite anode materials for its electric vehicle batteries, the companies said on Wednesday.

The "multibillion"-dollar deal, according to a news release, covers supply of synthetic anode graphite toward 2033.
