#72I think the best measure of real-world battery improvement would be a chart of iPhone / Macbook battery densities over time. My guess is that there's been little improvement over the last 10 years.
Maybe not in specs, but what about in specs per dollar? Surely there's been enough computer battery production over the last decade for Wright's Law to have an effect.

#73Lithium ion batteries set the standard because they have an acceptable level of all the key metrics: energy storage by weight; energy storage by volume; discharge rate; charging rate; production costs. Every single one of these big breakthrough announcements touts how great this new tech is- in just one or two particular metrics. The problem is that Li-Ion batteries are just barely acceptable in all of those metrics.…
Different battery designs and chemistries are appropriate for different applications. I don't care about how much a battery weighs if it never moves, for example.

There is already a car which uses two battery technologies in parallel.
This would also allow you to configure or offer cars optimized for the climate they are being used.
I personally also see those news more in 'im 5-10 years' we will have something much better than now.

#75Solid state might share the fate of Betamax. There was a post a while ago about a small scale battery manufacturer named Amprius, which reported 500Wh/kg batteries: https://news.ycombinator.com/item?id=35276709 Thing is, the company is producing 450Wh/kg batteries NOW and they're planning on scaling up their manufacturing capacity to 5GWh: https://www.convertingquarterly.com/ConvertingQuarterly/Indu...

EVs are already very heavy, and when the model 3 switched to LFP it got even heavier. This mass has lots of subtle consequences that aren't always appreciated. Like accelerated tire wear (which Tesla owners notice after they buy) and increased particulate pollution from that, increased road wear, increased danger to pedestrians and cyclists, etc. So, I'm less excited about LFP. There are a number of ideas in the work…
Independent of this, this also gives more and.better options for the energy grid in general.
And economy of scale: if we can produce it, the chance that we can scale it might only be a question of few years.

5 GWh in what time? Gigafactory 1 was at 30 GWh per year in 2019 and they planned to ramp up to 54 GWh, according to Wikipedia. So probably per year? Which would make their production capacity 570 kW. Also according to Wikipedia, a production of 35 GWh per year which is 4 MW was estimated to require 300 MW of energy input.
Energy input can be green.
If not now, at least doable.

This is according to CHATGPT so in terms of density you are probably correct though in terms of reliability speed of recharging there probably are improvements

#78>They explored coating its copper current collector with ultrathin lithium-activated tellurium. The aim was to control the way in which lithium metal spread across or “wetted” the copper. They found this new coating helped lithium metal deposit and dissolve from the copper current collector in a thin uniform layer.
Wikipedia: With an abundance in the Earth's crust comparable to that of platinum (about 1 µg/kg), tellurium is one of the rarest stable solid elements.

#79Earlier quoted context omitted.
I'm not sure about Toyota, because up till now they've been hydrogen evangelists and they don't have a great record on pure battery EVs.
Isn't that a given since the invest in solid-state?
Solid-state isn't going to fix the crazy high consumption of their EVs.

True (within limits), but the largest use of batteries is batteries that move. Utility scale power storage is the only significant use of battery that doesn't move. (there are others, but they are not probably large enough to develop a battery for, and so will be stuck with whatever they can get from the other markets)
