Maybe this could have a positive effect on electric MG range?

Miraculous breakthroughs are always just a couple years away. I know
it's true, cause they've been saying that for 20 years now.

Unless you consider NiMH to lithium a miraculous breakthrough I don't think solid state sounds like it's going to be a miracle. It does sound like it will be a significant improvement though.

Lithium batteries have been steadily improving year after year. The miraculous breakthroughs happen one small step at a time.

I call that a dramatic improvement in cost/benefit ratio. I'd noticed batteries, and items
like power tools that have a lot of battery in them, seem much cheaper now, it's even
better than I thought.

I think *any* move away from NiMH (including a move back to NiCd) is a
major improvement.

That's a nice graph. For one thing, both axes start from zero as they
should. And this is for LFP batteries, the "good" lithium... I hope
we'll see them used for motorglider propulsion soon. That graph ends in
"2019E" (eh?), I seem to have noticed a large drop in LFP prices since then.

The graph seems to show a levelling off of LFP price/kWh and a noticeable slowing in the improvement in energy density.

Shhhh. If the facts don't fit the narrative, you're supposed to ignore
the facts. That's how it works these days.

I got a real kick out of the interview with the CEO. In that video, he
had a chart of the Quantumscape stock price behind him, showing it going
to the moon.

Pulling up the one year chart, it started at $10, peaked at $132 in
December, and it's down to $27 now, and headed lower. The Gamestop of
the battery world.

The company is not in business to develop batteries, they're fleecing
naive investors. it's a classical pump-and-dump scheme, fueled by the
ever popular SPAC reverse acquisition. Very creative of them. All
sorts of wild claims, with no actual results to show for them. For a
more sober view of the company, read this:

Except, VW has tested Quantumscape cells and says they met VW's targets...

We will see. But only after many moons.

Lithium solid state batteries are still in the development stage, but there is a lot of interest in them by companies with substantial resources (i.e. car companies). I would not wait on them before deciding on which eglider to buy, however. Here is one assessment of the situation:
