if i can afford one, i’ll buy a car with it. but if i can’t, i’ll keep using my 04 nissan.

It’s unlikely you will see a car powered by those in near future if ever as they have relatively low density. But you’ll definitely see those as home battery and such where size/density doesn’t matter that much. And I bet it’s less inflammable as well.

In China NMC isn’t really used any more as a battery chemistry, almost all cars have LFP batteries. Sodium-ion has a slightly higher energy density than LFP. So basically almost all cars except the really expensive ones with a ridiculous range should switch over to sodium-ion pretty soon.

It’s still roughly half of the NMC. I wonder what’s the charging speed.

Per the edit, range will probably be fine. Na batts are already reaching the energy density of Li batts in EVs right now. It just takes a while for a new battery on an assembly line to get into actual car models. We’re not really waiting on any breakthroughs anymore.

honestly, I’m fine with a lower range. when i go into the office , it’s 15 km away from my house. i can charge up at home, drive to work, come back and charge it up for the next day, so as a daily driver it might be fine. The problem comes when I want to go on a road trip, which is my preferred method of going medium to long distance. I avoid flying like the plague, and trains are really expensive for some reason.

If I recall well, it isn’t a good fit for cars as it energy density per weight isn’t as good. But for residential batteries, that’s huge (if true).
felbane@lemmy.world 3 days ago
This isn’t true any more, and it’s mentioned in the article. Sodium is at least equivalent to - and on pace to surpass - the energy density of Lithium. It’s already being used in passenger cars in the Far East.

Even with an energy density disparity the lower potential for fires and lower effective operating temps it’s a huge upgrade for automotive applications. It’ll definitely replace all 12v batteries.
Dremor@lemmy.world 2 days ago
12v batteries probaby, but EV I’d doubt it considering how much range was a major hurdle to overcome. More weight, less range with the same capacity, meaning you need to add even more capacity, which reduces the space available for everything else.
My vision would be Li-ion will still be the king for medium to high-end EV, but for low-end EV, or those for whom range isn’t as much of a problem than for other (short range commuters) that would indeed be a game changer.
In my case, a 300-400 km range sodium-ion battery car, with a decent fast charge (less that an hour from to 80 percent) would be ideal. I use trains for anything further than that, and my car is mainly used for short range duties (less than 40km a day), once or twice a month. For anything closer than 20km I got my trusty cargo bike (which I use extensively, 2700km last year).

We got solid state to come challenge the car market in a few years. Supposedly both safer and bigger capacity. Just remains to be seen when it actually arrives in the average car. It’s a tech that hasn’t quite managed to get out of laboratories.
