It's the law of supply and demand. I'm repeating myself, but the Benchmark site reports that the company is building 240 plants at the moment, when it doesn't have the raw materials.
Volkswagen announced a few months ago that it would have to buy 100% of the graphite produced outside China in 2024 for its battery plants. As they don't have the raw materials, they will have to turn to us and others.
There has been a slowdown with respect to lithium during the COVID-19 pandemic. People felt that the raw materials were not available. Tesla and Volkswagen very clearly stated that they would need different batteries for different categories of cars.
As Professor Dahn was saying, there were variations—more nickel, less nickel, more graphite, more lithium—and then there was a big surge in demand. It was also felt that the South American projects were taking a very long time to develop because they mine brines, in a complex process that generates pollution.
Demand for electric vehicles also surged. As demonstrated by data around the world, demand is getting much stronger.
