Solid-state batteries also perform better in stressful environments, as they are less prone to overheating, fire and loss of charge over time, however they typically cannot discharge energy at the same rate as li-ion batteries.

Until now, this has made them unsuitable for powering large electronics, such as electric vehicles, as they require batteries capable of discharging their energy an incredibly fast rate.

This issue was solved by researchers at Nasa’s Solid-state Architecture Batteries for Enhanced Rechargeability and Safety (SABERS) unit, who were able to increase the battery’s discharge rate by a factor of 10 using innovative new materials that have yet to be used in batteries.

There is the bit that will make this infeasible “innovative new material”.

Battery tech is evolving fast. That’s no joke. There are many many billions being invested into new battery projects, and not all the companies doing it are following the same theories.

The issue is a battery factory takes 4-5 years to spin up. You need years worth of research and negotiation with many companies before you can build a building. Once you chose the vendor of equipment you have to build the building to their desired specs. These buildings are massive and complex. Lots of fire safety integrations and stuff like that.

So, your cutting edge battery factory is 2-5 years out of date when you open the doors.

I wonder what kind of discounts they use in planning a business case for a battery factory, given the tech and cost is changing so fast.

So many possibly outcomes. I imagine with that kind of risk they price in a lot of fat. Or push some of that risk to those buying the final product.

Depending on location, supply can be super volatile too. For instance if you source most of your lithium from China, and relations strain, things can get shaky on the market level real fast.

Validation for an automotive cell also takes about 5 years unless it is a mild chemistry tweak of a known good design.

Yup, R&D centers are easier to spin up with small production lines. But that won’t cut it for manufacturing in volume. So in year 2-3 of validation is when the buildings to scale manufacturing break ground so hopefully they will be fully productive at the perfect time.

That’s a serious gant chart. Lol

Aviation going to take a whole lot longer than that too

Yes it will.

A buddy is a Helicopter pilot and told me they replaced his twin batteries with a single battery from Tesla funny enough. The tech transfer is finally happening.

This press release of NASA actually describes what those materials are (selenium-sulfur battery):

it's irrelevant how fast a battery can be discharged. If you want to increase the power you just put multiple batteries in series. You can adjust by grouping them in series groups to increase voltage and parallel larger groups to increase the amperage.

Well hot damn, billions in research and decades of human endeavor was just made moot by pinkfootthegoose suggesting daisy chaining. None of them there scientists ever considered that.

I'm not the guy you responded to, I'm just curious. Why is daisy chaining not the solution?

How many double a batteries do you think it would take to power an airplane?

Wouldn't it be better to use less of a more powerful battery?

eldenrim t1_isyyxjr wrote

I wouldn't know how many, but I'd assume you can fit quite a lot in a plane surely?

Yes, that battery would obviously be better, but it doesn't exist yet, hence the problem with relying on renewables. I'm asking why daisy chaining isn't a valid solution, not why it's not optimal compared to all other possible batteries.
