So there wasn't really a lot of headroom for improvement on nickel metal hydride.

So the Department of Energy's work in that space was mostly done, but the, you know, the DOE had funded lithium batteries in the nineties, alongside of lithium nickel metal hydride.

That was obvious, a lot of work to do, but there was a lot of headroom for improvement.

And even after that, because lithium ion batteries sort of represents a family of chemistries, not a single chemistry.

And so, so that made it very attractive, uh, to pursue, uh, not only the potential, um, advances in battery technology, but, but also reducing the cost of potential to reduce the cost and have, um, um, you know, role, role to role production of, of batteries.

I was going to say, this was probably around the time that you made your transition from Oak Ridge National Lab to the Department of Energy to the Vehicle Technologies Office.

So, you know, we were finishing up nickel metal hydride work and, and then starting up.

So there were multiple pathways to pursue, you know, different combinations of cathodes, like I mentioned, some based on nickel, cobalt, manganese, iron, different flavors of electrolyte, okay, and electrolyte salts.
