DETROIT (AP) — General Motors is forming a joint venture with Posco Chemical of South Korea to build a North American battery materials plant as it brings more steps in the electric vehicle supply chain under its umbrella.

The Detroit automaker said Wednesday that details of the venture are still being worked out, including investment amounts and the plant location. GM said the factory will supply materials to make cathodes, the energy center of a battery that amounts to 40% of the cost.
