That feels like a very high bar. A really good 500Wh/kg battery would already be completely revolutionary. That’s when you start to unlock practical short range electric flights for instance. It’d probably be enough for all forms of land transportation as well (except very small niches, like if you need to cross a huge desert off-road)

If you get to 1kwh/kg I don’t think you even need good durability and low price to have a revolutionary battery. At that energy density it could make economic sense to do medium range battery electric planes, even if you need to replace the battery every year. The operational costs related to using jet fuel (both fuel costs and engine maintenance) are huge. So the airplane industry can work with batteries that are more expensive and that requires more maintenance than what the EV market would accept.

I’m sure there’s a bunch of other niches for such a battery.

It's definitely a high bar. I set it that way because there have been a handful of battery announcements claiming they can get to that number over the past 5 years. I want it and I want it now. Haha
