Yes. Thanks, Mark. Thanks for the question. Yes, I think the first thing is to -- the reason I showed some of the material in this talk is to actually show that most of the use cases in the smartphones, as the batteries get bigger and bigger and more and more capacity, are under 0.2C discharge, which basically means that we have a battery that now we believe under 0.2C average discharge rate, goes over 1,000 cycles. So we essentially -- we feel we have a battery that meets the requirements of the smartphone market. Now as I said, one of the challenges is if you want to test if the battery meets the requirements at the -- how the normally battery is used in the phone, it's going to take a year to at least to run that because if you run at 0.2C, it takes a long time. So customers typically use a higher rate of discharge, like 0.7C, to cut the amount of time it takes to test. This is very similar to people used to use a burn-in test, for example, for chips, high-temperature ovens, try to find the early failures. When you change technology from graphite batteries to silicon anode batteries, silicon anode batteries behave differently when you discharge them very fast, in this 0.7C. So Honor and our other smartphone customers, we've talked to them, they understand that. They realize that this test is a proxy and an accelerated test and not a true test. But, like you said, this is a test they have been using. So we are in discussions with them. We see 3 pathways forward. One is, we're able to convince them that this is not a real-life test and the real-life test is really 0.2C, and we can get a waiver on less cycle life for 0.7C, for example. By the way, this has got nothing to do with energy density. It's purely about cycle life testing. So it's not like they need to take a lower energy density. They just have to take a lower cycle life on 0.7C, which is not a real test, an accelerated test. The second one is we have to find together with them another accelerated test that is more representative, if you will, for silicon anodes. And we have some ideas on what that is, and we are discussing with them on that. The third one is we'll just have to modify our electrochemistry just to pass this test at 0.7C. So we are working on all 3 of those. Ultimately, there is a lot of interest from our customers in wanting to use our batteries because of the higher energy density we provide. And the road map, even higher energy densities because of 100% silicon anode. And those conversations are going well. But ultimately, we need to solve this passing of this test to a way where they and us both are comfortable, that in the real-life use case, when ultimately the battery is put in the phone, it's going to do really well and everyone is happy with the performance.
