“We got two cells, equivalent cells, same size on test in our lab right now. LFP is at about 26,026 hundred cycles, and it's at 80% state of health. NFPP is almost 3000 cycles same cell, and we're at 95 94.5 percent.”

Chinese sodium-ion prices will undercut LFP by 2030, Mossberg predicts
“From the quotes and what we're hearing from the suppliers, not just cells, but also materials, we see a really low-risk pathway to the crossover point on price with LFP coming somewhere between twenty-twenty-eight and twenty-thirty out of China.”
Waiting 4-5 years cedes sodium-ion economy of scale to China
“So if we wait for, Four or five years to get into this game, we're going to be in a similar place that we are today on LFP, but, ah, today at least, you're not facing such a huge, ah, economy of scale challenge.”
Peak Energy reaches balance-of-system cost parity with LFP today
“We try to depopulate a lot of the subsystems that drive cost, complexity, and energy density loss here. And what that lets us do is actually get to a balance of system cost Despite a serious energy density penalty that is already today pretty much on par with …”
Peak Energy's passive sodium-ion system uses 50x less aux power than LFP
“Just on aux power, we're 50 times, a little bit more than 50 times more efficient. We use 50 times less power than an equivalent LFP system.”
