Nah, see the battery density graph

Yah, I see your battery density graph and the batteries in question would blow a hole in that chart:

Samsung’s oxide solid-state battery technology boasts an energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries.

That's without even getting into the charging rates, which are impossible because you can't even deliver power to the car at that rate, even if it could take it.

suddenly there are trillions of dollars on the line for anyone that can make big strides in battery technology.

What makes you think that's "sudden"?

Yah, I see your battery density graph and the batteries in question would blow a hole in that chart, and several charts above it.

I'm not sure if we are looking at the same chart. The chart goes up to 500 Wh/kg, the same as this new Samsung battery as per the original article. It's may well be the same battery that gives the chart that value, but notice the years prior it gets higher and higher up to that value.

It might be 10 years away from being the mainstream battery but the battery technology that was 10 years away 9 years ago is almost here.

What makes you think that’s “sudden”?

I was meaning how EVs created a consumer market for huge batteries where prior to that the biggest battery in your house might have been a power tool. But you're right, there was a premium market for emerging battery tech and it increases along a scale like anything else.

Yes, that was my point, thank you.

Michael Thackeray filed a patent under Argonne National Laboratory for the leading EV battery chemistry worldwide today, Lithium Nickel-Manganese-Cobalt Oxide (NMC), sometime around 2007-2008.

The first cars with that specific technology started coming out in the US market in 2013/2014 IIRC, with EVs coming out before then basing their battery chemistry on NCA (Tesla) or LMO (Nissan Leaf & Chevy Volt).

That's a 5-7 year timeframe from laboratory to mass production.

If you consider new technologies today like Samsung's battery in this article, and make the not so unrealistic leap that we're better at battery production today than in 2013/2014, it's very possible that we see this technology hit the market in 5 years or less.

Technology always improves. It's CAPEX that hinders it, and I'm willing to bet that there are financial interests out there to keep the main battery chemistry NMC and secure steady profits.
