"Privately owned Tsingshan has become the world’s top nickel producer, thanks to its development of a low-cost process to make the metal.

It already has major investments in Indonesia, including other joint ventures with Huayou.

Volkswagen’s second joint venture will be formed with Huayou in China’s southwestern Guangxi region for the refining of nickel and cobalt sulfate and cathode material production, it said.

“The cooperation aims to achieve significant cost advantages, secure the raw material supply and achieve a transparent and sustainable supply chain,” it said."

So maybe Volkswagen is thinking Tsingshan for the stainless steel and Huayou for the battery materials. That's fine if it's the case, there's more nickel in the stainless steel of an electric car built to last than there is in the battery.
