Small correction that was not clear in the video. I said that the discharge/charge curve for Li-Ion, LiPo and LFP (LiFePo4) is about the same. That is not completely true since LFP or LiFePo4 comes with lower voltage levels. But their voltage does also not drop that much. It is pretty flat across the whole discharge region. This is what I was trying to say.

I put together a sodium ion power tool battery. The voltage drops a lot while running (internal resistance). For a car tire pump it's not too bad because it works at a lower temperature, so I can leave it sitting in my car in the winter. It's definitely a lot larger (physically) battery than the li-ion equivalent. I don't plan on making any more power tool batteries out of sodium ion. I'm thinking of making an off-grid solar panel system for my garage specifically to charge an electric car, and as an emergency (extension cord) backup for the house.

Andy @Off-Grid Garage has been doing some significant testing of sodium batteries (not cells so much). The wider voltage range and sinking discharge curve compared to the nearly flat curve of LiFePO4 is rather a problem until/unless off grid electronics is designed for the wider voltage range.

@@cygil1 I specifically mentioned off-grid. I'd like to see a comparison between these commercial sodium ion batteries and the classic nickel-iron batteries. Sodium-ion have a similar wide voltage range disadvantage but if these are not using nickel then cost (at least short term) would favor sodium-ion. (some sodium ion chemistries also use nickel but many do not) Nickel-iron is an old and wonderfully robust and durable chemistry for stationary applications. Nickel isn't cheap and energy density is low. Wide voltage range (similar to sodium-ion) was also an impediment. However the batteries are capable of daily heavy cycling for decades then a flush and cleaning of the anode and cathode and refill with fresh lye (electrolyte) and they are good to go again for decades more. Con-Ed in New York used 100 year old nickel-iron batteries for load management on their D.C. grid until just a few years ago. Some old installations were also used after the D.C. grid was shut down by doing local rectification to power a facility grid, with surges handled by the batteries.

Nice! When calculating the W/$ should really consider also the life of the battery. Natron Energy's bluepack claims 50-100K cycles so if you buy 100Kw lithium for home storage you will need to replace it every 5-10 years while with sodium probably you will never need to replace it.

Create robot to slay your enemies, extract the sodium from their blood, use sodium to forge new batteries, repeat.

The number of charge cycles is very impressive! One big problem that sodium batteries faced was that the larger size of the sodium ion would lead to greater expansion when the ions intercalate (move into the space between carbon layers) into the graphite. This would lead to the graphite breaking and parts of it then being electrically isolated and thus no longer active in the battery. It's very cool that they found a way to avoid this. I just hope that this is not why they have higher internal resistance because that may mean that the resistance cannot be reduced without sacrificing the battery longevity.

My experience with "no-name" cells is generally that they perform the most below-spec in terms of cycle life even if their initial values are otherwise fairly good, and I suspect it's largely because of low quality/purity ingredients used in their manufacturing.

I'm excitedly waiting for these to become more mainstream. I have a small off-grid cabin, and currently have to do a lot of worrying in the winter about my LFP batteries. The wider operating range of sodium, with similar density to LFP, is going to be a lifesaver as I increase the size of my energy storage

Once the price drops, these are going to be amazing for home battery systems.

you are correct with the comparison of LFP and Na-ion. that’s the strategy cell suppliers are marketing for. the first run of these are going to be in large stationary energy storage arrays where you need good cycle life but not high rate charge or discharge.

A fact that was missed here witch is a big plus or pro is its temperature range. Being able to go down to close to freezing and still charge

8:46 There are smart BMS boards that allow you to set the maximum voltage and minimum, cut-off current, and temperature protection, so this is not a problem. For example JK-BMS

These will be great for long term use and large-scale applications where space isn't an issue like a powerwall or electric generator etc.

Lithium took a while to evolve as well. Glad to see battery chemistry competitor.

Ohhhhh that is a very useful technology!!!

Great Scott! ❤👍

Very informative 🤓👍

Oh, that's cool! Good to see newer battery chemistries actually showing up on the market rather than remaining vaporware.

finally i can get myself a good off grid power solution, im ready to wait about a decade to get commercially available sodium ion cells, and i think itd be the best alternative for lead acid battery at kind of similar price.. better than LFP tho

Nice test and conclusion for a new technology :) I think we will have to wait a bit till these become a real alternitive to current batteries, but as long as size and weight is not a concern, I can see these replacing them (in a hypothetical case where they are 10 times cheaper while offering 1/2 or 1/3 of the capacity) I guess it could also be a problem with the lower max constant current, but in what applications do we have a 100% current draw on current battgeries that cant be fixed with just adding more parallel battery cells?

That's very cool Please make an update in some time

Thank you for providing the first review on the Sodium battery. I didn't expect this new type of battery to become commercially available this soon. However, I'm a bit frustrated that you didn't open the battery enclosure to show us its internal materials or test its potential for explosion.

I punched 1 no flames just smoke

Safety and sustainability are my main considerations. I'm excited to see how the chemistry develops!

I've changed to lithium iron phosphate. These cell seem to work and not have safety problems. Although they don't like being charged below 0 Celsius and don't have the density of lithium ion batteries but I can live with that. Thanks for the heads up on the salt batteries.

Thanks for the shout out!! ❤

Great video, thank you.

Yay! Sounds exciting! :D

Can we get some temperature test comparisons? Can this be used on larger scale for energy storage in colder climates?

The sodium ion battery will become the defacto standard I think. There is a place for higher density batteries or higher current output batteries. But for electrical grid battery storage, be it at scale or at home, and for alot of electrical electric vehicles I think this will help and incentivize more environmentally friendly energy usage due to it being economically better priced per Wh
