Toyota claims breakthrough with their solid state battery — full charge in 10 minutes with over 1,000 km of range by 2028

Well, if this is really true (Toyota is no new or small start-up) it is certainly going to tick all the major boxes remaining for EV batteries as far as economic requirements go.

Ease of manufacture, range, charge time, and safety were some of the biggest factors holding many back from adopting EVs.

Yes, price is also quite a big factor, but if this is produced at scale, or even is slightly smaller sizes, the price factor can be overcome. I’d be quite OK with having a 500 km range battery that could charge in 5 or 6 minutes.

One issue not mentioned, though, is whether there is any improvement in the rare metals environmental impact. That will probably still factor lower than the other considerations, though, mainly because EVs already have an overall lower impact than ICE vehicles.

New Flow Battery Using Simple Sugar Has Year Long Charge Duration For Grid Storage: A Healthier Use For Sugar

Diagram showing how the parts of a flow battery work
The discovery could lead to new low-cost, long duration energy storage systems that can write fossil energy out of the picture by capturing wind and solar power for weeks, months, or even whole seasons.

To provide full day, utility scale energy storage as more wind and solar power enter the grid, a flow battery fits the bill.

I really love that there is so much research, and the associated results flowing back, around all sorts of different approaches to batteries. Without a doubt, grid storage is now the big thing needed for variable power generation technology. Being storage, it can also be located where it is required for use.

EU: Samsung and other brands may be forced to bring back phones with removable backs so that we can easily replace batteries

Bild/Foto
Gone are the days when we could easily take off the smartphone’s battery and replace it with a new one. You didn’t need a heat gun or a specialised tool to pop open the back of your phone, and you could easily do that with your fingernails. It seems like we could get the good old days back, thanks to a law passed by the European Union.

According to a new report, the European Parliament has changed a previous law that will force all gadgets, including smartphones, to have easily replaceable batteries. The MEP’s vote count ratio for this change stood at 587 to 9. The term ‘easily’ means that users should be able to replace the batteries without requiring special tools.

This means OEMs, from Apple to Google to Samsung, all have to make drastic changes to their smartphone designs (by 2027) to adhere to the new change that asks them to mount easily replaceable batteries on their devices.

Yes, my experience (a Nexus 6P) has been that it is usually the battery that wears out first, causing a perfectly good phone to become largely useless unless you want to risk the almighty pain of heat guns and levers to pry the phone apart. I did a battery change once, and it is just not something I really want to do again.

I know manufacturers are going to say it is about size (well I’ll gladly have a slightly thicker phone) or water resistance (I’m sure designers can come up with something again that includes rubber rings etc). I do get the feeling that manufacturers deliberately went the route of sealed phones so that we get pressed into buying new phones every two or three years. Now we have longer software updates, but batteries die after three years or so.

It is not just about the environment, but I’ve also seen that so many disposable products actually become far more expensive for users (for example cartridge razor blades).

The Sodium-Ion Battery Is Coming To Production EV Cars This Year, Such As The Chery iCAR

Diagram showing the layer components of a sodium battery
Sodium is also abundant, but unlike lithium, is readily available. Sodium — one of the primary components of table salt — is chemically similar to lithium, and thanks to the explosion in lithium carbonate prices, many companies are researching ways to use it to replace lithium in the batteries for electric vehicles. Sodium is an attractive alternative to lithium because it costs only 2 to 3% as much as lithium. Imagine what that price difference could mean to the price of new electric vehicles!

Despite being chemically similar, sodium-ion batteries today have considerably lower energy density than lithium batteries. Things are moving quickly in battery development. The sodium-ion batteries available today will likely improve just as quickly.

On the other hand, sodium batteries are much less affected by low temperatures and appear to be able to handle more charge/discharge cycles than lithium-ion batteries. The latest sodium batteries do not require scarce materials like cobalt and nickel. Both CATL and BYD say they are about to introduce EV battery packs that have a mix of lithium-ion and sodium-ion cells.

So as is usual with battery technology, there is not yet any read drop-in better replacement for Lithium batteries, especially for EVs. But what is also quite usual, is that money is being pumped into research to radically improve these various alternative chemistries. And what is also certain is, that even if these batteries are still not compact enough for EVs, they will have a place so long with grid storage and similar use cases.

This Register article summarizes the situation better than anything I've seen yet. Goes over all the major alternatives to lithium ion and the magnesium, lithium-sulphur, sodium ion, solid state, etc. etc. We got lithium-ion thru a confluence of economics (Sony's idle thin-film factories converted to battery film manufacture) and chemistry.Battery boffins therefore think that lithium-ion has at least a decade of dominance ahead of it.​

"The battery industry is all about cost," says Sam Jaffe of Cairn ERA, a battery research outfit. "And cost is a function of scale: you need big factories and mature supply chains. That's not something you can build overnight. It took lithium-ion 15 years before it went from a highly specialised product to more of a mass-market product. That will be true of any upcoming battery technology: it takes decades."

For solar, the dominant powerhouse is the much safer, longer lasting, deeper cycling, and CHEAPER lithium iron phosphate..

NanoGraf Technologies claims it has developed the highest energy-density cylindrical 18650 Lithium-ion cell in the world, with an energy-density of 810 Wh/L (4.0Ah capacity).

"Ampere hours (Ah) is the amount of energy charge in a battery that enables 1 ampere of current to flow for one hour."

"In 2021, NanoGraf announced it had developed the world's longest-running 3.8Ah 18650 cylindrical lithium-ion cell, at 800Wh/L, so this latest version reflects an improvement."

The battery is something called a silicon-anode cell. "A silicon anode battery is a type of lithium-ion battery where the anode is replaced by silicon nanotubes or silicon coating."

They never say what Wh/L stands for. Watt-hours per liter? Ok, so, you all know your metric units, right? Watts are a unit of power, watt-hours are a unit of energy, liters are a unit of volume, so watt-hours per liter is energy per unit volume, or energy density. So it makes sense.

Who uses this type of battery? Tesla? Brrrrrp! I tracked down the original press release (from May of this year) and it says NanoGraf Technologies sells this battery to the military.

Pourquoi la #voiture #électrique n'est pas la solution miracle pour se déplacer sans polluer
https://www.francetvinfo.fr/meteo/climat/pourquoi-la-voiture-electrique-n-est-pas-la-solution-miracle-pour-se-deplacer-sans-polluer_5425306.html

Tout cela est du #capitalisme, créer un nouveaux marchés. Et on est bien loin de quelque chose d'écologique.
En même temps, #Macron le met en avant, donc on sait que ce n'est pas pour l' #Écologie.

Autant dire de suite que de multiplier les vélos électriques ne fera rien de plus que de rajouter de la pression sur les #Électricité #ressources en #métaux rares, #Cobalt, #Nickel, #Manganèse, #Lithium... Les #batteries donc...

Un #VAE actuel, c'est le #Solex de mon grand-père... Ben du temps de mon grand-père, on faisait encore la différence entre un #vélomoteur comme le Solex et un #vélo... Bizarrement aujourd'hui, on n'en est plus capable... Bizarre, vous avez dit bizarre ? ....

Pourquoi la voiture électrique n'est pas la solution miracle pour se déplacer sans polluer

A l'occasion du Mondial de l'automobile qui se tient à Paris, Emmanuel Macron et le gouvernement veulent promouvoir cette filière, pourtant pas si vertueuse.
