New battery technology to replace lead-acid and lithium

[Hella_Wini22]

LEt me guess - yet another Na-Ion cell ?

Take your ticket and stand in line. 🤣

Na-Ions have been hyped during last years as a robust and cheap alternative to Li-Ions, but then... problems have creeped up.

Just like with perovskite solarpanels and so many other things.

But now, just like with perovskite panels, those problems seem to be slowly getting resolved.

And just like with panels, first cells are to come out in a few years.

And just like with panels, those things are probably going to be far off initial bombastic claims.

I think Toyota's recent announcements are more interesting here. That's a level-headed company (despite the crazy hydrogen experiment). When they say their new battery technology giving 1500 km range will be in 2026 models it's probably best to believe them.

Toyota have been making as many grandiose claims about the next generation of batteries as anyone else. Why should we think the latest claim is any better than previous ones?

Toyota are extremely conservative especially about anything that could harm their reputation as making the most reliable cars in the world. For example they introduced their first mass-market pure EV only in 2022, ten years after experimenting with a very limited release Tesla-powered RAV4 (a friend in California has one), and 25 years after introducing the hybrid Prius.

If they say (as they have) that these batteries are in their 2026 models then they have for sure been doing real-world tests with prototypes for years already.

Or it is just smoke and mirrors to keep shareholders happy. IIRC Toyota announced to have solid state batteries in their BEVs by 2023. Well, that didn't happen. And it doesn't need to happen. Keep in mind that unlike many other car manufacturers, Toyota doesn't have to sell BEVs at all (except in China) to meet CO2 emission quotas AND be profitable. Their hybrids are doing just fine. Their Bxyz yadda yadda isn't very special as a BEV. Toyota can simply wait for their long term hydrogen strategy to play out. Note how the EU market for BEVs seems to have reached a point of saturation causing serious trouble for all car makers. Except Toyota.

The fuzzy promises with three different batteries of varying chemistries doesn't inspire confidence.

Lots of companies promising production of metal anode battery EVs in the same timeframe. Stellantis/Factorial, Nissan, Chery.

Hopefully some of them will work and cause the current 500 km range EVs (model Y or so) to drop waaaaay down in resale value by the time I'm thinking about replacing my current turbo Outback in another 100,000 km or so -- currently on only 149,000 of which I've done 62,000 in 4 1/2 years, so that's in around 7-8 years at the current rate.

You just need to sign the NDA and then you can attend one of the presentations and hear about it and ask questions.

Can you send us an unsigned copy of the NDA so we can read it first before making any decisions?

The NDA presumably names the parties involved so I guess you aren't allowed to read it until after you agree... /s

Of course, how else would you sign it. I sent you a PM. It's not some long elaborate contract, it's just a simple agreement.

Sounds scammy, or someone has had their account compromised? No posts since August then this? Also the IP address doesn't match the location and comes back as a high risk for fraud. Hmm...

If this wasn't an established account it would have been instantly deleted as spam.
I've emailed the OP for confirmation.

OP has confirmed the post is legit, not a compromised account.

It might even be a legit business made to look like a scam

I mean, it happens. In 99% of the cases, if it walks like a duck and quacks like a duck, ... But that leaves the 1%. If the OP is serious then this kind of "yo dawg guys on the internets, I have a secret technology which makes you a billionaire, you just need to..." is a pretty crappy way of dealing with the business.

As with every new battery, they are literally a dime a dozen. I could have a full time Youtube channel devoted to news of new battery tech. Almost all of them amount to nothing. 99.9% chance of losing your money on any battery company investment.

But Daveeee how are we going to get excited for cell phones that charge in 3 minutes or EVs that charge in 15 minutes if we discount every no detail "ground breaking" battery startup.
