Every day it feels like we're getting closer to battery revolution. It really makes you wonder how different the world will be once we have these incredible batteries actually working at consumer level.

[-] Ghostalmedia@lemmy.world 34 points 3 months ago

They’re coming off a pilot production line and have shipped to vehicle manufacturers to see if they want to incorporate these into upcoming models.

Problem will be the price for the first run of this tech. They’re targeting “ultra premium” vehicles until they can scale and optimize manufacturing.

The market will segment away from the current tech anyway. CATL Sodium-ion with comparatively low densities but also extremely low prices per kWh will likely win the low-end market and the market for stationary solutions. This is just due to the much lower resource costs. The high-end will be up for things like this battery by Samsung (or other comparable pilot products). The current technology will likely be in a weird middle spot.

And those cheaper batteries may not be as compromising as people think. In terms of kwh/kg, the sodium-ion batteries coming on the market now are about where lithium poly batteries were about 4 years ago. It takes a few years before new batteries make their way into EVs, which means EVs being purchased right now have batteries with a similar kwh/kg of the new sodium-ion batteries. Those batteries are around 30% cheaper and don't have the same level of fire hazards as some lithium chemistries.

So if EVs on the market today have adequate range for your use, you'll probably be just fine with a future sodium-ion EV.

There won't be many charging stations able to output that kind of wattage tho

Can you imagine not having the constant traffic noise played into your ears like tinnitus, being able to maybe actually breathe the oxygen nature provides. That’s probably gonna be what it will be like. But still, ev are just a stop gap, more privately owned cars isn’t the solution in my humble opinion, it is a start towards it.

[-] Imperor@lemmy.world 16 points 3 months ago

Totally with you, but tire dust is one of the major pollution particles from cars, maybe even the worst AFAIK. That, sadly will not go away but it is still leagues more desireable to have everything on electric than fossil fuel. Can't have perfect stop good enough.

[-] Mihies@programming.dev 4 points 3 months ago

Yep, tire pollution is even worse with EVs due to their weight. But overall it's still much better as you said.

[-] vividspecter@lemm.ee 14 points 3 months ago

It would help if cars went back to a reasonable size and not the absurdly large monstrosities that dominate the market today.

[-] Serinus@lemmy.world 6 points 3 months ago

It's even hard to find an EV sedan. There are like 3 models under $70k. Everyone wants to make SUVs instead.

[-] frezik@midwest.social 2 points 3 months ago

That's the real kicker. Gets especially hard if you don't want a Tesla.

Many of the conservatives who cite heaviness of EVs as a problem didn't say shit as ICE cars got heavier and they bought F150s to go to Walmart.

The tire noise EVs make is about the same as an ICE car at about 50 kph (30 mph) so it doesn't make much difference on busy roads. It does make a huge difference in slow traffic.

The traffic noise will stay the same, from tires, honking and some fake engine noise they'll mandate for pedestrian safety.
Do yourself a favor and spend some time in an area without cars. It's amazing what it does to your mental health.

[-] BastingChemina@slrpnk.net 4 points 3 months ago

About noise, above 30km/h electric cars are as noisy as gas powered one.

It's better but not the panacea either.

[-] vividspecter@lemm.ee 4 points 3 months ago

Solution: 30km/h speed limit in cities, which is a good idea anyway for safety reasons.

[-] BastingChemina@slrpnk.net 2 points 3 months ago

Yes, it's better for safety and health reason.

Plus 30km/h is in the speed range of bikes, so it become much more accessible to bike around in the city and more people start to do it.

[-] Corvid@lemmy.world 2 points 3 months ago

It’s 30mph not kph. City streets should be limited to 20mph anyway.

we’re getting closer to battery revolution

If big oil doesn't buy up the patent and squirrel it away.

[-] P1nkman@lemmy.world 1 points 3 months ago

I waited 4 years for battery technology to get better before bring an EV last year. The "battery revolution", with all the news being generated weekly for years, is still not here. I don't give a fuck about theoretical battery range - give me the actual battery in a car, THEN it's newsworthy. Now it's all just theoretical, which we consumers can do fuck all about.

[-] Serinus@lemmy.world 8 points 3 months ago

And that's the thing. As much as we've gotten used to it over the past hundred years, progress is absolutely not automatic.

If people don't buy the current stuff, it reduces the chance of advancement for that tech. Most things will only get better if people are buying the current versions.

We've had solar power tech for 50 years. Solar initiatives under Carter were actually pretty good. You know who killed it, or I expect we'd have solar on most roofs today.

I recently visited Switzerland, and the amount of rooftop solar there was insane.

(Solar is of course closely linked to battery tech.)

Well, Toyota has promised 2026 for their battery tech and hasn't changed that guidance, so I think there's a decent chance they'll stick to that timeline. I don't know if Samsung is their supplier or if they're competing on the tech, but if it's the latter, I expect we'll see something in the next 2-3 years.

[-] jballs@sh.itjust.works 2 points 3 months ago

I'm still convinced Toyota is just announcing breakthroughs miracles in battery tech Coming Soon™ because they shit the bed so hard on the first round of EVs. Now they're trying to discourage people from buying EVs now while they play catch-up.
