I compare solid-state battery manufacturing, to extreme ultraviolet lithography.

I remember reading about attempts to commercialise EUV lithography in the early 2000s (in a paper magazine!) The same issues that SSB have now - some lucky examples from tiny yields in the lab, but the devil's own problem to scale it and develop reliable manufacturing.

ASML was able to commercialise it in 2018. I expect the timeline for SSB to be about the same, twenty years or so. I think we will see it but not until the 2030s.

My EQE with its very mediocre battery, claims to get ~300 miles but actually gets about 350 when I drive it.

And that is already pushing the limits of my bladder. I can't imagine ever wanting to drive further than that without stopping.

semi-solid-state cells

Those have been around for a while. There are already prototype full solid state cells. Nobody has a good production process yet.

Is the Solid State Battery claimed by Mercedes-Benz safer than the batteries currently used in EVs? In 2024, a Mercedes electric vehicle caught a major fire in my country (South Korea), which has led to a rise in electric vehicle phobia and even places where parking is completely prohibited.

SSBs will not only revolutionize ground transport, but more importantly air transport and drone tech.

Given it has such high military value and those customers can pay very well, I predict that they will see the first uses of this tech.

Another better battery Bulletin :(

It's always the companies without a solid mass market EV that are promising this.

Another day, another better battery for consumer product promise. I really hope one day we will get rid of stinking non electric cars from the streets.

isnt the prevailing issue with solid state is that they're both expensive to manufacture AND they have a short lifecycle? (ie the lifespan of a solidstate is about a 1/4 of a NMC and even less that of a LFP)
