They say in the title "All Standard Range Teslas", but only the Model 3 has a standard range version and they're still like 2-3 years away from their compact/25K car.
Does anyone know if 20 years from now these batteries start to burn down homes will Tesla be required to fix the problem similar to how traditional auto companies fix bad air bags or whatever issue that could kill people even decades later?
The linked article's title is "Tesla made $1.6 billion in Q3, is switching to LFP batteries globally" and it's a little more appropriate as it split about 50-50 between discussing earnings and discussing battery technology. I say this because there’s another article from the New York Times about Tesla‘s earnings on HN's front page and this one from Ars is more technical, more straightforwardly written, and much less…
What is the situation these days with infringement of major IP by Chinese companies? If they've had a battery chemistry to themselves for a while it sounds like they're having their cake and eating. I have first hand knowledge where at the small and medium scale, Chinese manufacturers will happily knock off major brands and steal technology to make products, and as a non-Chinese IP owner you have very little recourse…
Completely agree. I had a thermodynamics teacher in college say “in the history of transportation we’ve never switched to something powered by lower energy density [than the previous mode of transportation]" in other words “energy density wins the day".* That was running through my head when I read they were switching to technology with lower energy density but, to your point and to the article's point, it’s really a…
Exactly how many data points did he have in this thesis? Running, horse, bike, car, train (coal, electric, diesel), plane? There's lots of places which have flip flopped, e.g. Italy going from train -> Alitalia -> high speed rail
Wouldn't it be more like running, horse, better horse because of improved diet, better horse because of improved medicine, bike, better bike because of gears, better bike because of better gears, car, better car because of better fuel, better car because of better fuel, better car because of better fuel, better car because of better fuel, better car because of better fuel, better car because of better fuel...
Article notes worse cold weather range with LFP vs NCA. What's the approximate range hit at 0C for each type? -17C?
when I read the article this was what stood out to me, as well. Last winter it got _really_ cold where I live. Does that mean that if I got a Tesla with an LFP battery it would be drastically less useful in the winter? Seems problematic.
The battery can be heated, so you can reduce the cold weather range problems by preconditioning the battery before a drive. Naturally this uses some power, so Tesla recommends keeping the car plugged in when it's cold so it can keep everything nice and warm.

Tesla opened all their patents… so not sure what you are referring to?
Would be interesting to know whats going on in the industry with LFP. Pre-built lead acid replacement LFP battery prices have been dropping almost daily and are down to high end AGM prices [1] and quality has been going up [2], these batteries were twice the price a year ago. Will be replacing the lead acid in my RV soon with LFP's, it really a no brainer. 1. https://www.amazon.com/dp/B08FMTRYPT 2. https://www.youtub…
Basically people figured out how to make them energy dense:
What will the Gigafactory be doing? Does this mean Tesla's battery-supply advantage is gone?
No, they'll be gobbling up any reasonably priced cell they can get their hands on for the foreseeable future. There was a part of Battery Day where they explain their approach to battery chemistry, here is the slide: https://cdn.motor1.com/images/mgl/JvxPA/s1/2020-tesla-shareh...

The Y had standard range for about a month and it seems to have sold well, but since they have a 6 month wait on long range, why bother right now?
