Innovation Sodium ION batteries

[izentrop]

CATL unveiled a sodium-ion battery at its "Tech Zone", and it already has many highlights: "Based on a series of innovations via the chemical system, the first generation of sodium-ion batteries from CATL has advantages such as high energy density, fast charging capability, excellent thermal stability, and very good low-temperature performance, among others,” the company’s press release reads.

CATL thus offers a battery capable of being recharged up to 80% in just 15 minutes at room temperature. An efficiency that should widely appeal to allow a certain saving of time in the context of regular use. Thermal stability is also an advantage of this technological innovation since it retains nearly 90% of its energy, even at freezing temperatures of around -20 degrees. Ideal therefore to try to seduce the Nordic countries...

Sodium-ion and sodium manganese would be the same battery

Altech Batteries, a battery technology company in Western Australia, has included "breakthrough" sodium chloride technology in its new 1 MWh Battery GridPack. He said he expects the new systems to be up to 40% cheaper to produce than mainstream lithium-ion alternatives.

The principle of Na-Ion is inspired by Li-Ion

Lithium and Sodium are also from the same chemical family, the alkalines.

However, sodium is heavier, and therefore less mobile. Energy densities are lower than with Lithium.

The advantage of ionic sodium is that its resource is accessible and inexhaustible (eg in sea water).

it's been a long time since we hear about the Na-Ion battery, but so far she proved disappointing in cycling and/or mass energy density.

Is there anything new ? The future will tell.

In 2012, I made a short summary of the main battery electrochemistries

who hasn't aged so badly!
Here is about Li-Ions
Here is concerning Nickel Cadmium
Here is concerning lead

2012? too heavy ? the Chinese electric car released in February, not so bad, right?
They also support the cold better and fix it, we don't care about the weight.

This first Sehol EX10 prototype features a 25 kWh battery (with a density of 120 Wh/kg), and allows the vehicle to enjoy a range of approximately 250 km.

The “standard” version (lithium battery) of the vehicle is offered in two versions, 19,7 kWh and 31,4 kWh, for a range of 200 and 300 km respectively.

our current production cells provide a nominal specific energy (at 4,2 V) of up to 160 Wh/kg in 32 Ah pocket cells. Faradion's next-generation sodium-ion cell design will deliver a nominal specific energy in excess of 190 Wh/kg - this has been verified in prototype pocket cells and we are currently scaling it up to 32 production scale pocket cells.

I was talking about the Sodium atom compared to Lithium, not the automobile.

You know Izy, it's like for the COVID, don't believe the high-sounding press releases...

And 120 Wh/kg is really mediocre, it takes us back to the NiMH generation of 20 years ago...

Maybe in stationary battery, if cheap and highly cycleable. But for cars, the Li-Ion will remain competitive, except on the low end, perhaps.

The current data indicates that this technology has a future, but good if the knowledge of 2012 is enough for you.

[Remundo]

like with COVID, you talk about what you don't know.

You throw out stuff you like, taking it for granted.

you haven't even seen that at 120 Wh/kg, we're less than half of Li-Ion

and you allow yourself to be con-descending with me...

you really are a jerk here.

For me Na-Ion may have a chance to break through if it is not too expensive to produce compared to Lithium and if it confirms a high cyclability. That's all I'm saying based on the few data coming out in 2023 and which should be taken with caution.

heh, it's not new carbon, already used by Sony in 1991

To power high-performance electric vehicles? what is the breakdown voltage?
Are you sure we're talking about the same thing? Aren't you afraid that there is a Penning ionization with high voltage and a carbon anode? I say that...

While it markets the first consumer product powered by sodium-ion battery technology, the CNRS spin-off Tiamat has other major projects. Its president, Hervé Beuffe, tells us more.

You sell a cordless screwdriver at Leroy Merlin. Why is this a key milestone for your Tiamat business?
Hervé Beuffe: This marketing is our very first and it is above all a world first of which we are very proud: no other company in the world has to date marketed a consumer product powered by sodium-ion battery technology, whoever she is. This cordless screwdriver will be on the shelves in some Leroy Merlin stores from October.

This also marks a new structuring stage for our start-up Tiamat, created in 2017 and based in Amiens: from next year, we will have to deliver several tens to several hundred thousand cells each year, to support the adoption of sodium-ion technology by this customer.

(...)

What does this sodium-ion battery technology that you have developed bring?
HB: The batteries that Tiamat designs, develops and produces are based on sodium ions. They free themselves from the lithium and cobalt usually used – resources in tension whose geostrategic dependence weakens sovereignty – and overcome certain limits. Thus, our batteries are more durable – with a lifespan of 10 years compared to 3-4 years for lithium batteries under conditions of continuous use – and 10 times faster to recharge (in just 5 minutes). And this, at a cost equivalent to technologies based on lithium. It is therefore an ecological, economical and reliable alternative.
