Thanks so much, guys. You know, could you talk a little bit about how you're tracking performance of the material and cells, you know, as you move forward with these arrangements and what that can do for your cost profile?
Sure. Good to hear from you, Colin. Yeah, as I think you know quite well, we're still in the early stages of cell design. Our customers are continuing to evolve their cell designs, their chemistries, their binders, their solvents. And so a lot of the work that has been done is around improving our performance in their chemistries, number one. Number two, we focus very heavily on quality, so a lot-to-lot consistency and the tightness of certain specifications that are really, really important to our customers. things like particle size, et cetera. Each customer seems to have their own requirement there. So we're focused very heavily on controlling that and delivering to their expectations. Long-term cost, we believe we have a structural advantage with our wet process. We've done a lot of work through the joint venture partnership work with potential partners in Korea that have dry processes. and we've been able to actually benchmark our long-term roadmap against an equivalent capacity output for a drive process. And again, we believe quite strongly that we have a structural advantage there. So that would be my comments on the performance as well as long-term cost roadmap. We intend to be the cost leader as we go through our commercialization phase and on up into ramp.

Excellent. That's super helpful. And then I guess the second question is really around, you know, customer development in the U.S. and potential for manufacturing domestically as we see an increased level of regionalization around the battery space. And obviously, you guys have multiple options and multiple opportunities, you know, internationally as well. But just curious about the development of domestic customers and what they're looking for from a production perspective.
Yeah, six months ago, we started getting signals from the humanoid robotic companies. And since then, it's picked up quite considerably there. There's a number of U.S. players that are expressing interest in all solid-state batteries because of the advantages in energy density, safety, and charge rate. So I would say some of those discussions are advancing with some of the leaders in the space right now domestically. We still do not see any domestic manufacturing of cells. at that scale. But that could change with the coming quarters. But we definitely have seen an uptick in humanoids since we last reported. We also have gotten a small amount of interest from defense and aerospace markets in the past quarter.
That's helpful. Thanks so much, guys.

This concludes our question and answer session. I would like to turn the conference back over to John Van Scoter for any closing remarks.
Thank you for joining the call today and for your interest in solid power. We look forward to updating you again next quarter.
