#2"CATL has announced a new “condensed” battery with 500 Wh/kg which it says will go into mass production this year"
This is a lot more credible than most of the battery stories, because CATL is already producing a ton of batteries, lending them some credibility.
This is a little under 2x the density of current batteries.

Hopefully not more than 2x the cost...

#4Why does 500wh/kg make electric aircraft possible? 6x less than kerosene. Is that the break even on cost if you can source very cheap electricity?
Seems like it would still annihilate the payload/range.

#5Cool! What didn’t occur to me until I learnt it was that you get a multiplicative benefit with energy density when weight is a major factor (air transport, especially) because you need to spend less energy accelerating mass used by the battery itself.

More than 2x the cost might still be worth it for doubling car ranges and potentially making electric flight possible.

I assume it's a limit motivated more by how far you can go rather than the cost of fueling/charging. Like, above a certain weight/energy store ratio, it's either too heavy to fly or would just have an incredibly limited range.

Seems like marketing hype to me. An 8-hour transatlantic flight requires something like 600MWhr of energy. That's about 75MW, which is in small nuclear reactor territory.
