The catch is that this is a tiny lab prototype, where the energy density is projected and I could not find it in the paper that the cycling was in fact tested for 1000 times and even though the starting materials are cheap the article is very light on details about mass manufacturing larger cells. I don't want to take away from the research and think it's super cool and hope it scales well to mass production but it's usually a long road from lab prototype to Tesla level production facilities.

But how long? Longer than 300 miles?

Almost all inventions you hear about in the lab phase like this NEVER make it to production.

But sometimes they do.

Argonne got NMC to market. I wouldn't discount Argonne.

For anyone else curious, NMC is probably https://en.wikipedia.org/wiki/Lithium_nickel_manganese_cobal...

> Lithium nickel manganese cobalt oxides (abbreviated Li-NMC, LNMC, or NMC) are mixed metal oxides of lithium, nickel, manganese and cobalt. They have the general formula LiNixMnyCozO2. ... NMCs are among the most important storage materials for lithium ions in lithium ion batteries. They are used on the positive side, which acts as the cathode during discharge.

If interested in battery technology and Argonne I'd recommend this book: "The Powerhouse: America, China, and the Great Battery War" [0]

To quote Terry Pratchett:

99 out of every 100 ideas they come up with are complete rubbish, but the 100th tends to be an absolute humdinger.

Take a commonly held opinion. Something that all the smart people hold to be true.

Frame it wisely and wittily enough for fast food. Feed it back to those smart people.

That's Terry.

Take someone who's achieved something. Someone widely admired.

Shit on them. Imply there was nothing impressive about what they did and it wasn't worth doing.

That's HN.

As opposed to the miracle of selection elsewhere.

Most of these inventions don't live up to their initial hype, but some do find a niche (for example cell chemistry optimized for large temperature ranges, optimized for certain safety features, longevity over charge density etc.), and ideas from some of them find their way into mainstream batteries after a decade or two.

It basically never happens that a new cell chemistry becomes the market leader in all areas, but all in all, batteries to get better and cheaper at a remarkable rate.

The team established that this shortcoming is not the case for their new battery design by building and operating a test cell for 1000 cycles, demonstrating its stability over repeated charge and discharge.

I read that in the article but in the paper I only found a mention of tests for 200 cycles.
