CATL Licensing New Sodium EV Battery Technology

This lays out more than the OP

Yep. Great for large scale storage, not so great for EVs.

 

Scooters are also predominantly driven in warmer weather climates, so the cold rating advantage of the Sodium/Lithium hybrid doesn’t really come into play. When an Arctic sub-zero cold weather pattern hit the US this summer, many news channel’s reported frustration of owners with EVs. This is a definite problem with Lithium/Phosphate. We’re all familiar with ICE lead acid battery degradation in extreme cold.

I think the NA/LI hybrid is very close, and probably even available today for mass production. CATL introduced the NA battery in July 2021. I don’t think it’s a coincidence that they mention this technology in conjunction with their announcement of the licensing partnership agreements. Unlike other Chinese companies, CATL is usually conservative when making these types of claims.

One other item- the article does mention power storage, but it also specifically mentions EVs.

 

This is why all Chinese claims are to be taken with a grain of salt.

Because of dogs? CATL has been remarkably consistent in their claims. Tony Seba is arguably one of the best Corporate CEOs in world business.

 

He's an entrepreneur. And all Chinese claims are suspect.

 

And you're a social media poster. All claims are suspect.

 

As you wish.

 

Lithium Ion batteries continue to drop in price. Hybrid Sodium Ion batteries have the potential to brings the prices down even more.

Battery costs for EVs are dropping faster than expected, as CATL and BYD are producing them for as low as $56/kWh. Over time, this could translate to even cheaper batteries over the coming years and decades.

 

There was also talk of graphite batteries

hmmmm seems there is n issue with supply chain and graphite even fir just Lithium batteries

If it is not on an unsourced blog…….

 

Awwwww! They are cute! It never ceases to amaze me that the same people who line up to accuse China of misinformation will swallow the rubbish from astroturf sites

 

NBC News?

 

Maaate I didn’t say that China or rather some grifter in China was not peddling misinformation but at least the Chinese did not vote in a known liar, grifter and sexual offender as a president

 

Then your comment was an off-topic irrelevance.

 

Well you were first down the rabbit hole of misinformation I just followed

 

The topic was Chinese (lack of) credibility. Your comment was an off-topic irrelevance.

 

Sodium batteries are similar to lithium batteries but have some differences.

The sodium battery is cheaper and more environmentally friendly than lithium ion, but it is also heavier and therefore does not allow the same driving range.
It's also just a little bit more dangerous than lithium, when it comes to fires and trying to put the fires out with water.
(The main reason for this is that sodium has a significantly lower melting point, so in a fire will pour out into a puddle and could even splash, rapidly increasing the surface area exposure to air)

One big advantage of the sodium battery is that there does not really exist enough lithium for everyone in the world to be able to have an electric car running on lithium batteries.

The use for which sodium batteries would be particularly suited is for stationary battery banks to store large amounts of electric power, where weight will not be an issue, sodium would be much more economical than lithium.
(Storage of electric power will probably be necessary to be able to reach 100% renewable energy generation, but it should be kept in mind that any form of storage of large amounts of electric power in batteries is much less economical than generating it on demand)

 

I believe they are called graphene. They are actually Lithium Ion batteries, with graphene used in select battery locations. This technology is still in a difficult research phase. Last I read there were some internal Tesla leaks that talked about some very difficult challenges with mass production.

Here is CATL's description of the Sodium Ion battery in July of 2021. Thermal stability is a property of their sodium Ion batteries.

https://www.catl.com/en/news/665.html

CATL’s first generation of sodium-ion batteries has the advantages of high-energy density, fast-charging capability, excellent thermal stability, great low-temperature performance and high-integration efficiency, among others.

You should also read the link the link in the original article of the thread, because they are now licensing their 2nd Generation Sodium Ion batteries. One of the most exciting newer battery technologies was BYD's Blade battery, because it passed a "nail penetration" test. It has an energy density of 190 KWH/KG. The hybrid sodium ion battery, which CATL describes, has an energy density of 200 KWH/KG, lighter than the Blade battery.

Personally, I don't want to carry a lot of battery weight around. Give me 100-150 mile range, and I'm good for 99.9% of my travel, and my car will be lighter than most ICEs,
