One might love that idea so much we fail to notice that no answer to a problem was revealed by this expensive work.

The heat stress cracks did not even form in the expected pattern.

The sodium ion cathode material that to me seemed most exciting was the "Prussian white" (lithiated ferrocyanide)- basically the sodium ion equivalent of iron phosphate for lithium ion batteries. That material contains nothing that isn't positively earth abundant. Rather than trying to force Na ion into taking part of Li ion's mobile device and EV market by using NMC cathodes, producing giant volumes of very low cost per kWh low energy density Na ion batteries for use in grid storage seems to me to be the best bet, and you aren't going to get the cost very low if you keep using NMC cathode material, irrespective of how stable you make it against cycling-related cracking!

They are on their gen two Lithium Fe Po cells including new short blade cells and gen two Na ion cells that are matching earlier Li Fe phospate. Now they are playing with Li Sulpher cells. What CATL has said is they are ditching all NMC batterys for Automotive and propulsion and storage use. Just wont be sustainable for the cost and volume required. 🤔 Ever had the feeling that certain people were being paid a large amount of money to convince joe public that they should keep sticking their heads into the scientific tar pit .🤡 🤨.....😂 Now if someone can produce an Al based cell fossil fuels really are dead ... "Aluminum contains a great deal of potential energy. By volume, it contains twice that of diesel fuel and forty times what a lithium-ion battery can store. With the discovery of their novel process, Kombargi, Ellis, and Godart have managed to unlock the abundant metal’s potential for practical use."

[@teardowndan5364]

Cooking materials at 1/5th the speed takes ~5X as long, which means you need 5X as much oven space to achieve the same throughput. Not the most dramatic thing to scale up and that cost is likely offset by the simpler preparation. This sounds a lot like hardening vs annealing. If you rapidly quench a hot metal, its crystalline structure gets frozen in place faster than they can re-shape themselves to relieve stress and you get something harder than if you let the same metal slowly cool down. Similarly, the hardened metal is more brittle than the annealed version.

As an engineer this is a pattern I see often. The US engineering community has been weakened with cracks running through it caused by decades of outsourcing production, a form of “capital flight”. Excellence is still possible but roadblocks develop when organizations have no access to additional research resources or experimental data from iterative development. Both capital and time intensive. This is ok in the cooperative environment globalization promised, but is now a big problem with political bad actors seizing this experience, or intellectual capital. We in the US and Europe are in a pickle if we do not mobilize our material research resources quickly and seed industry with the data they need to create whole new generations of processes. NASA did this before. We need something like NASA for electronics and micro-scale systems.

_"caused by decades of outsourcing production"_ which is being caused by a technical flaw in our currencies that drives companies to provide perpetual profit, even in plateauing (what we had) and shrinking (what happens now) economic environments, which are mostly coupled to population dynamics (thus normal developments). Engineers could fix that, but social sciences doesn't seem to have them nor their knowledge (control engineering).

[@TomMcinerney-g9b]

Thank you for informed comment.

[@TomMcinerney-g9b]

@NoAlbatross - A couple points: (1) After the '79 increase in US energy costs, American production became much less competitive. (2) After election of Reagan, the coincidental expansion of Leveraged Buyouts transferred control of corporate assets from traditional management (with Some loyalty to company) to accountants with short term, extractive goals (versus investment). (3) For owners of companies, offshoring production yields lower costs, and often increased profits. (4) In 2009, I spoke to an elder acquaintance for first time in 45 years. He'd retired as a managing director at Morgan Stanley. He said, "We [in Wall Street community] are supposed to invest in Productive Assets in USA ... We are Not doing that". During Obama admin was initiative to invest in battery R,D&D. One company spun off from the initiative (Ann Sastry batteries) was sold to British firm Dyson; another, '1,2,3 Battery' was sold to a Chinese outfit. See trend? (5) China offers land to companies nearly free. US protects real estate interests at expense of manufacturers. (6) Every economic downturn since 1980 has been met with policymakers decreasing funding for education. The average vocabulary of American high school students between 1970 and 2000 decreased by half. Until recently, Chinese students began learning English language from age 2 years. (7) Senator Mitch McConnell torpedoed the US economy in effort to prevent a second term of office of Obama. In marked contrast, JFK, as a Senator, wrote book, "Profiles in Courage" about legislators who voted for National interests, rather than parochial interests. (8) The politics of USA, especially after the Citizens United decision, are now Controlled (rather than advised) by lobbyists and other moneyed interests. When EE (algorithm expert) Frances Haugen testified before US Congress that Facebook transitioned from a nurturing community to a source of anxiety and insecurity upon the incorporation of algorithms which maximized participation, that were devised by AI, lobbyists prevented the legislators from changing the new algorithms. (9) The US invaded/occupied Iraq based on false premises. When, upon invading Afghanistan, the Taliban offered to turn over Osama Bin Laden, the US military declined the offer. The invasions of Iraq, Libya, Afghanistan, and Syria were planned before 9-11, and continue.

my argument was simplified and shortened by AI The evolution of battery technology parallels the history of home wiring, where the need to balance cost, performance, and safety has driven significant changes. Just as the industry initially moved from copper to aluminum wiring for cost savings-only to return to copper due to safety concerns-battery development has followed a similar path. Modern batteries, such as Lithium Iron Phosphate (LFP) and Sodium-Ion, are gaining popularity as safer, more sustainable alternatives to traditional chemistries like lithium-ion cobalt variants. These newer options prioritize long-term reliability, safety, and reduced environmental impact, reflecting a shift in focus from maximizing energy density to achieving a more balanced, sustainable, and practical solution for diverse applications.
