Solid-state batteries enter pilot production, costs expected to drastically drop

I wish the article would give more information on the comparative advantages and disadvantages of these “semi-solid state” batteries. It handwaves at improved energy density but doesn’t get specific. I’d be curious to know how this fits into the picture of gradually improving LI batteries.

It's not much of an article. This one was much better, with more specifics: https://news.ycombinator.com/item?id=41979906

The non-solid have evolved so much during the last year that now the solid ones are not even better in density. However, I assume the solid state batteries can evolve further since this will just be the first generation.

Normally the promised benefits of solid state batteries were these: - More density - More safety - More cycles - Better in high and low temperatures - Probably cheaper in the long term

At the moment LFP batteries are caching up with a lot of these improvements and the sodium-ion also are starting to improve, reduce price and offer advantages in extreme temperatures. Their density is not good but I think for homes and large storage facilities they can also be a winner if they become very cheap.

Where is QuantumScape?
