We're going to see less of it. The prevalent cathode is the nickel-cobalt manganese cathode. Where at one time, going back five years, about a third of the material was cobalt, now we're down to a point where we're somewhere closer to 10%. Tesla would be down to 5%. You might see that go to 3% or 4%. It's hard to take it out, because nickel gives you range and gives you energy density, but you need the cobalt to preserve the battery integrity to keep it from overheating and catching fire and also to preserve that battery so that you get your 10-year life.
With the people I'm talking to, when you hear executives talk about a cobalt-free battery, they're not cobalt-free. They're low cobalt. It just sounds good to say no cobalt.
