Well all those graphs show is that the cost of batteries has gone down and that as a result electric cars contain more batteries and therefore more range. It doesn’t actually show that the individual battery capacity has increased.

It doesn’t really dispute it, though. Lithium-ion has seen a lot of improvement, yes, because it’s already a giant industry; other battery chemistries have a hard time breaking through because they require entirely different processes to manufacture.
I’m still rooting for it, but it’s not really the same thing.

This too is false, great progress has been made on for instance solid state batteries.
tb_@lemmy.world 3 weeks ago
Some progress is being made, but it hasn’t seen large-scale adoption yet. Which is the point, as I read it.
Buffalox@lemmy.world 3 weeks ago
It takes time to scale up production, CATL is supposed to deliver in small scale production next year.
That means the factories for it are already about to be built.

The “progress” is typical industry bullshit. See the absolute bullshit around the Donut SS battery.
Remember when Musk invented a battery with 30% better capacity? It was a 30% bigger battery.

It takes time to scale production and even more time to adopt a new technology.

You can’t buy anything with solid state batteries yet, and when you can, they will cost a fortune.

Uhh you know you can buy an external mag safe battery bank with a solid state battery for like 45 bucks on amazon as well as the big generator ones as well?
I agree that cost isn’t amazing. You are essentially getting about half the capacity per dollar spent to a standard battery device but also these are in fact more stable for temp swings and damage. Soo… consumer available and not a fortune just need to have justification for it.
