This is like the 100th battery breakthrough article I’ve seen in the past 5 years. Is it safe to get excited this time?

No.

It's tech, we rarely have revolutions, we usually have evolution.

All those breakthroughs will help battery tech getting better, one step at a time.

Which is exciting in its own way. But more of a "I'm really happy to see progress" and not "the world will be forever changed after this comes out" kinda way. I'm excited that we are getting more and more knowledge about the subject and am hopeful for great things in the future.

There's not a ton of data in the NASA article, but it's made out to be a new architecture with unprecedented chemistry. Correct me if I'm wrong, but if it's as wildly successful as they predict would it not be revolutionary?

I've been reading about battery tech breakthroughs since 2008 or so. It's normal that such things take 5 to 10 years to become commercially available and only a fraction manages to get there at all.

Most people aren't aware however how much battery tech developed in a disruptive way. For the past 2 decades, battery prices per kw/h halfed roughly ever 4.5 years. This is due to all these advances that people think never arrive in products because there are so many news on it.

You can see the historic price development graph here: https://ourworldindata.org/battery-price-decline

And btw, for photovoltaic and wind energy, the price development looks fairly similar.

sorry, but price is - at least for me - not THE relevant factor, but energy density is.
Look at this brand new electric vehicle - it only costs 37000€ instead of 38000€ but you still only get 200km range out of it.
yeah.

Daily, few ppl need more than 100km if they can charge at home

This is the one thing keeping me from getting an electric vehicle. There is exactly a 0% chance my apartment will put in a charger so I'm stuck for now

The worst part is they just need a couple dedicated normal outlets in the parking section. Most people would be fine charging their car off a tradional 13A outlet. 1.5-2 kWh would result in 6-8 kWh over night. And at an avr of 0.2kwh per km we get between 6-8km/h so over night that should be 30-50km which is much more than the average city travel.

I know plenty of people who have an electric car in nyc. Apartments don’t have them there. They charge when they go grocery shopping or travel. I do realize that we don’t drive as much as most people though so that might not be realistic for everyone.

Suicicoo t1_irwq4eh wrote

yeah, but i don't drive daily, i do most of the stuff in 20km radius with the bike or the cargobike (or with my 50ccm moped)
The distances i use my car for are usually between 400-1100km...

For situations like Urs it would never really be green or economical to go electric. If you can use ur personal transport vehicle or public transport the majority of the time it would be more polluting to get an electric car than it would be to just continue as your were and rent gas when you need distance. Untill we hit some massive breakthrough in battery tek I really see electric as the way to offset our daily travels and then maybe a hybrid solution for long distance

Hard to say, this particular application is pretty early in the R&D phase, but that said, solid state batteries in general are really picking up steam lately, we’ll be seeing a lot more of that tech coming to market over the next decade hopefully. I’m cautiously optimistic

fiendishrabbit t1_irvij69 wrote

It's exciting if you want battery-powered short&mid-range aviation. Otherwise...eh. Depends entirely on how much the battery costs.

Increasing solidstate battery output is one of the things the industry has struggled with over the last 30 years though.

The pipistrel airplane is available today. It’d be nice to increase its range.

No. Batteries have a quite expansive list of relevant factors. If there was a breakthrough that doesn't have a major negative downside on any of those factors we'd be reading it in the respectable science magazines, not on MSN.

Looks like the only downside here is the scarcity of selenium.

It’s on NASAs website too and it’s pretty significant. I’m an EV engineer and I’m excited.

random_shitter t1_irww26c wrote

Are you excited about the battery development or did you have a cupcake?

1

cocaine-cupcakes t1_irwx6lo wrote

Lol actually the battery development. Too early for Pam’s cupcakes. What I like about this is that it’s being used on a functioning prototype vehicle, not a bench test in a lab. I’m sure it’s outrageously expensive still and the cycle count is probably lower than ideal but private sector engineers should be able to improve those factors over time.

brwntrout t1_irwae2j wrote

i'm excited because it's NASA, not some private engineering firm making spectacular claims for publicity.

brainimpacter t1_irwwjvh wrote

I hate to be skeptical but I wouldn't be too optimistic, Exaggerated claims are made all the time by government funded researchers to get budget increases from the engineering and Science illiterates in charge of making the funding decisions.

Solid state batteries are the future and they will make gasoline engines obsolete…….once we can scale them up to be used in vehicles. Not just a gamechanger an Earthchanger.

The OLED screens that are starting to appear in consumer products were first developed 15(?)ish years ago. It takes a long time to go from "developed technology" to finished product. There are also possible unknown issues that may keep this tech from scaling up to useful production. On the other hand, when you see lots of promising developments in a field in a short period of time you can be pretty sure that some of them are going to work out. So you can't bet for sure on this tech, but it's a good bet that something in development now will work out.

LotusCSGO t1_irw83bd wrote

No. The news that will cause people to actually get excited is when large scale manufacturing is figured out for any of these tiny and lab created proof of concepts.

We've had "better" battery technology for years. We just can't make any of it at any kind of scale.

Could you please provide examples of drastically improved batteries that are unfeasible for general use? Genuinely curious.
