Solid-state batteries charge in a fraction of the time, run cooler, and pack more energy into less space than traditional lithium-ion versions.

Solid-state batteries charge faster, last longer

Evidently they also have a soft green glow.
- That’s the plutonium needed to get to 1.21 gigawatts
- So you save on lighting.
since when are normal batteries not solid-state?
- Since they use liquid electrolytes, which leads to dendrites formation on the cathode and anode of the batteries, which can end up shorting the battery. The point of solid state batteries (if they ever can be made at scale) is to prevent that with (hopefully) better energy density and charge time than our current battery tech
How do they weigh versus a lithium ion?
- Supposedly more energy dense.
- Compared to a single lithium ion? Probably a lot more.
  Seriously though google says solid state batteries weigh 1/3-2/3 of lithium ion batteries for the same capacity depending on the source.
That sounds promising. Good that they link to the research too. Not enough articles do that.
- I'm not gonna hold my breath about this, because "breakthrough in smaller better battery tech" is a recurring headline seen for the better art of 20 years.
  ... But I am convinced that the next major leap forward when it comes to advancement of practical applications of tech that isn't stationary is going to involve a breachthrough in regards to battery capacity and size/weight. So as usual I'm curious where this leads.
  Once we have something practical for the open market, we're going to see a lot more portable applications for tech, and I for one am looking forward to it.
  
  “breakthrough in smaller better battery tech” is a recurring headline seen for the better art of 20 years.
  And the batteries we have today are VASTLY better than what we had 20 years ago. Progress is always slow, but as far as batteries are concerned the progress that's been made has been incredible.
Is this completely solid state or where some components are solid state?
