Can Tesla Make Use of This Battery Chemistry That is More Efficient Than Lithium?

We have a video showing a sodium battery chemistry that is supposedly 4 times more efficient than Lithium. This comes from the University of Sydney in Australia.


New Battery Chemistry 4 Times More Efficient Than Sodium

As the world transition to sustainable energy, Energy storage is going to play more of an important role. Tesla sells Megapacks right now from its Lathrop, California factory and is scaling to sell 10,000 per year at $2 million per Megapack.

This is just from one factory and Megapacks are moving away from Lithium batteries to an LFP battery chemistry, which is more appropriate for stationary storage. Lithium is better for EVs that want more performance and Energy density. Stationary storage doesn't need high performance, it just need stored Energy.

At the University of Sydney in Australia, there is a battery chemistry being developed using sodium that is supposedly 4 times more efficient than Lithium batteries. After 1,000 charge cycles, the batter retained half its capacity still. That would put it still twice as efficient as Lithium at that point.

However, more testing needs to be done to make the batteries more efficient and quality control on the longevity of the batteries will be important as well before they are put into commercial products and vehicles.

The cost of Sodium is quite less than Lithium right now due to the high demand of Lithium. This would drive down the costs of EVs and stationary storage if this battery could be proved. And if it did, the demand for it would go up, which would most likely increase its price too.

Sodium is easier to mine than Lithium and easier to process.

Can Tesla Make Use of this Battery Chemistry?

Tesla uses two primary chemistries for its batteries right now - Lithium-ion and LFP batteries. The Lithium batteries are used for most EVs except the standard range vehicles that don't need fast acceleration or power and for stationary storage in its Megapacks.

Tesla could make use of Sodium right now, but it would be risky. The reason is that the battery chemistry hasn't been widely proven to have a problem free lifespan and testing hasn't been thoroughly done in EVs.

For Tesla to make use of this Sodium battery chemistry from the University of Sydney in Australia, they would have to allocate a portion of their staff to test this new battery. I think it's worth doing to prove if it is viable and indeed 4 times more efficient than Lithium.

It is the commercialization of this sodium battery that is the bottleneck to the future of it. Like all successful products and innovation, there has to be an extended testing period. Just look at Tesla FSD. It has been tested for many years now and will still be tested for years to come.

I was scammed by a Bitcoin investment online website in April. I lost about $350,000 to them and they denied all my withdrawal request, and gave me all sort of filty request. It was a really hard time for me because that was all I had and they tricked me into investing the money with a guarantee that I will make profit from the investment. They took all my money and I did not hear from them anymore. I was able to recover all the money I lost just last month with the help of Proasset recovery. I paid 10% of the recovered funds as his service charge after I got all my money back. I am really grateful to him because I know a lot of people here have been scammed and need help.

Le batterie al NaFP (sodio ferro fosfato) riscuoteranno un grande successo sia perché saranno meno costose delle LiFP (Litio ferro fosfato) sia perché la chimica dello State Solid e' più semplice di quella con Intercalazione ionica su Grafite e Hard Carbon ma soprattutto si è notato che le NaFP presentano una maggiore densità di carica. Inoltre la redox di carica e scarica è assai facile da comprendere
verso sinistra Scarica
NaFP= Na + FP
Carica (verso destra)
Il sodio darà un sacco di pensieri ai magnati del Litio

When I couldn't login to my crypto wallet, I was introduced to so many recovery software's and firms, but all to no avail until, I used Folkwin Hacker's ([email protected]). That is the best recovery platform I have ever used, very fast and reliable.
I will rate Folkwin Hacker's 5 star anywhere anytime. Contact Folkwin hackers if you have any problem concerning hacking, they are fast and reliable

‘’I need back my money’’.. ‘’ I need my family back’’ that was the only thoughts I had for months and thanks to Albert Gonzalez Wizard , I got back my family and my money .. I was depressed for months as my husband and 5year old left me to go live with his mum cos I used all our savings to invest in crypto investment company, took a loan and sold my car too in a bid to pay the withdrawal fees I was desperate very desperate and I nearly lost everything but thanks to Albert Gonzalez Wizard , he recovered my £861k from those heartless scammers .. it’s a long story but at the end I was happy , I am forever grateful to him.. This has made me to cross paths with him through a review on here and am writing this review here in hope that it will help someone out there , if you’ve been in a similar situation please reach out to Albert Gonzalez Wizard, he is a very competent and reliable hacker .
