So solid state battery tech is very likely on-schedule for mass production over the next 4 years. There really isn't much time left for the haters to post stories attempting to factually dismantle and dismiss EVs before EVs pass the 51% adoption curve in 2030.

Even as things currently stand, some folks just have a bone to pick with EVs. Even if future models have an 800mi range, can charge to 100% in 5 minutes, and have useful lifetimes as long or longer than ICE counterparts, some will figure out some reason to get angry about them.

It's fine, those folks can just get angrier and angrier as the market makes their ICE cars more and more difficult and expensive to own.

> Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density This is damn impressive. I suppose all the makers of military drones are lining up at the factory already. I mean, electric bikes are fine, but who has the most burning need to increase range and payload?..

i don't see them mentioning of price and C-rating. Suppose their C-rating is sufficient. Current widely available cheap batteries are almost 300Wh/kg. So, on a 3 kg drone with up to 3 kg payload (say RPG-7 single shaped charge warhead) with say 30 min flight time the new battery will give you 10 min additional flight time. At what price? If the price results in having only one 40 min drone instead of 2 30 min drones,…

I agree, but I suppose most batteries in circulation at the front lines are not fresh, and likely have 75%-90% of the original capacity after intense discharge-charge cycles multiple times a day. If his battery does not deteriorate as quickly, it may be worth the price, for non-kamikaze-type drones. Not a shaped charge and ramming into armor, but a mortar round dropped from 300-500m, undetected. There is a ton of videos on YouTube with footage from such bomber drones.

10 extra minutes may mean extra 5 kilometers of range, or of a patrol / recon route.

For me current battery tech is already good enough for passenger ev they cant even use the full charging speed capacity or the charge discharge cycles. Solid state batteries might be useful for heavy duty trucking or aeroplanes/drones

Cost, volume, and weight are still significant constraints. Existing batteries obviously can make for some good cars, but they could be better. It doesn’t have to be more range or faster charging, it could be the same range and charging speed but 25% lighter and cheaper.

There's no mention of the underlying cell chemistry on the landing page or under the "battery" tab, and only three people listed under the "About Us" of which the only one who sounds remotely technical is Ville Piippo, so I punched him into Google Scholar and found this:

https://aaltodoc.aalto.fi/items/a9608639-3897-4878-979b-0d95...

If this guy has developed a revolutionary new battery cell then he has really learned a lot in ten years.

So we have no chemistry and no researchers but this startup claims to have blown everyone else out of the water. We'll see, I guess.

Samsung originally scheduled production next year, but apparently it will be this year, ahead of schedule, and apparently winning the race.

They're behind, Toyota announced in 2017 that they would begin solid state battery production in 2022: https://www.greencarreports.com/news/1111717_2022-toyota-ele...

I would take solid state battery announcements with a large grain of salt.

I'm still waiting for the EV that's a car instead of some kind of techbro reimagining of personal transportation with a 27" tv glued to the dash. So far the plug-in hybrid market is figuring that out first -- the Mazda CX90 is a real car. The VW ID3 gets close, but it still feels like someone tried to design a B-movie space ship.

There's a great market out there willing to buy B-movie space ships, but if EVs are going to be the default (and I think they are) they're going to have to get over the toys and start shipping cars.

I’ll take the under on that.

I guess we'll see what happens in ~5 years

Some models of the motorcycle are available right now and can charge to 80% in 10 minutes and go ~350 miles. Unless it is a scam, and you will not get your motorcycle... However, this seems legitimate.

The models with the new battery are preorder only, and with a price tag of $35k.

The tech needs to go to another company that can produce something more people are able and willing to buy, and that's going to take a few years before it has a meaningful impact on the market.

It’s range anxiety and it’s real. And it’s not entirely unjustified. Where I live in the Midwest I have literally never seen a public charging station. I know they exist because I can search for them on maps app and I see dots, but it speaks to their general small numbers that I’ve never seen one in person that I can remember.

Now, prior to this, I lived in California for many years from 2011 until 2019, and I saw tons of EV charging stations there. I left with the impression of “wow, charging stations are everywhere”, and that was 7 years ago.

But now in my Midwest metro area, I can honestly say there are zero that I can think of within a 10 mile radius of my house. Not one. (They’re out there somewhere, but they gotta be tucked away because I never notice them enough to remember them.)

It’s no small wonder that all my friends from California drive electric cars, and all my friends from this area (near my childhood home, so I know lots of people) think EV owners are crazy. [0]

If EV charging stations were visibly everywhere and charged in 5 minutes I could say without a doubt that every one of them would be swayed. So I don’t think they’re being irrational at all.

- [0] It is common to go on long road trips here, since the weather sucks, and people really don’t want to rent a car to do it. Plus a ton of people tow shit. Half my friends have campers and the other half have boats.

That is true even if you take LFP for China, Global South & lower range urban vehicles and LMFP or High nickel Lithium ion batteries into consideration in a place where rational thinking persists.

Solid state if it works at scale at right price might give the killer blow as the no of excuses will shrink even further
