Reply to comment by giggidy88 in NASA has invented a new type of high-performance battery that researchers claim could be used to power fully electric airplanes. by phife_is_a_dawg

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So, your cutting edge battery factory is 2-5 years out of date when you open the doors.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