Looking forward to similar discoveries in the sodium ion batteries.
These numbers are cool, and we may never see them that high with sodium, but we really need to get them to the level when we could use them in things like powerbanks and electric vehicles, and not just grid-scale storage.
Of course it is. It’s not rare and can be recycled.
Lithium is relatively rare, and very environmentally damaging to mine. Recycling is absolutely a must, but, as with any recycling, the recovery is not 100%.
Sodium is obviously hugely abundant and we already have relatively eco-friendly salt mining for many centuries.

What are non-solid state batteries up to, in Wh/kg? Because my car with an 82 kWh battery would need about 215+ kg to reach the same charge with a solid state battery.

About 350 it seems. There is a typical value section

That’s pretty great, for the solid state battery then. Looked it up and it seems like the battery weighs about 500 kg in my car. Very significant change down to only 215–216 kg.

260 Wh/kg in a good modern battery.
scams or definition issues. There was a bunch of stuff of what made it solid state percentage wise and if only one part needed to be it. Granted I do think it should not have liquid components if its going to be called solid state.
