A 3x capacity increase is huuuge but a >10x cost increase is prohibitive except for applications like aircraft.
Earlier quoted context omitted.
Given that presumably Tesla's goal is to take battery costs down by 56% in 3 years from (108 - 140 $/kwh) to (50 - 70$/kwh) and widely held consensus is that 100$/kwh is the price point at which EVs are no brainer on upfront costs with ICE cars, i feel that there is a long way to go. However, i think any successful real world demo starting with niche applications will help. We need all the battery tech to succeed.
Electric airplanes need significantly better energy density.
airbus is already jumping on it
IF this is true, it would be a massive breakthrough. Truly monumental. Hence, I am skeptical. But otherwise, this would be a massive thing. a 2x capacity per weight advantage of batteries? Without an increase in space? That comes down to doubling the range of EVs, and making electric planes and rockets a lot more viable. A 3x capacity per space advantage means roughly a 3x improvement in your phone and laptop battery…
What exactly is an "electric rocket"?
https://en.wikipedia.org/wiki/Electron_(rocket) Is the big player in the field afaik.

Presumably a rocket with a power source separated from its exhaust, and that flings its exhaust material out with an electrically-powered device. So basically think of a 'reverse railgun'.

>Or, more likely, a slight improvement in your phone and much thinner phones. On laptops, we might see the return of more ports. // Please, no. I don't understand the utility of making something so expensive be so fragile and hard to hold. My phone is 5mm thick, that's already too thin for me. Does anyone want thinner phones or is it just a marketing thing?

Medical devices, wireless headsets, phones, drones, various pro-grade cameras and gear - there are many devices where expensive batteries would still be economical. For some apllications, you need fixed amount of power, perhaps you could have 3 times less batties, at 3x the price. That frees up space and reduces weight.
Reasons I'm suspicious: * article leads with "in production" but it sounds like they are still at the design phase. production of prototypes maybe? * they are doing a lot of "talking" and "partnering" but not so much selling mentioned. * they are "known for" their similar work in the ultra-capacitor market but the linked page's top comment is "still waiting for a product". * PR about raising funding and starting soon…
Nope, I don't think so; battery breakthroughs are reported (probably) several times a month, but what eventually becomes available to the consumer is more evolutionary than revolutionary; we've NEVER experienced a 2x jump in battery capacity for example, it's always been incremental.
That said, I may need to take that back; this page (https://cleantechnica.com/2020/02/19/bloombergnef-lithium-io...) seems to indicate that li-ion battery capacity seems to have doubled or tripled since 2010, while prices dropped by 87%.

Not counting turbopumps for chemical engines there is also an electric propulsion when in space.
