Thanks alot. I’ve been waiting for this video and now my understanding of the limitations of recently proposed sodium-ion battery chemistries have improved. This has been very helpful. I’ll be looking closely at the sodium ion battery manufacturing industry for improvements in cost efficiency for the energy storage market over the long term. 😃👍

Note: In the video I said Sodium Ion will be poorly suited for vehicles. I didn't say it wouldn't be used in vehicles. Will we see sodium ion in vehicles? This actually requires its own video because there are half a dozen variables and those variables will evolve through time. That is, which country, which manufacturer, and which year do you want to know about? In the next 5-8 years, not for Tesla in the U.S. and Europe in my view. Also: How do you define vehicle? A golf cart is a vehicle. How will the CO2 profiles vary between the chemistries? How will the chemistry affect BMS systems? How will the energy density of sodium ion evolve over time? For Tesla, Sodium ion is unlikely this decade for vehicles because Tesla's priority is vehicles. Vehicles with LFP will be more efficient and require fewer kWh. So, they'll likely shift the LFP athat would be used for energy storage, use that for vehicles, and use the sodium ion for energy storage (as per Drew's comment about energy storage). This is exactly what's currently being done with Nickel and LFP. LFP is pushing Nickel out of the energy storage space and Nickel is pushing up the ladder to Cybertruck and Semi. So, could Sodium Ion be used for vehicles this decade? Yes Will it? Yes Will you drive one of those vehicles? Probably not, they'll be for low cost beaters in China and India who will take any scraps. This is exactly the way that LFP was used for 10 years before Tesla started using it. So, maybe you'll see Sodium Ion in a Tesla in 2030 if things go sideways. Will that likelihood increase with time? Maybe, maybe not. In the early 2030s there will be new lithium ion cathodes that drive down the cost of lithium ion so low that it could be competitive with sodium ion at much higher energy densities, plus huge volumes of recycled material will start to become available. So, I don't think anyone has the answer here on what chemistry will be dominant in the 2030s. It will likely be a mix of chemistries depending on the use case. Will it better for the environment to use sodium ion than LFP? No, because it'll be less efficient and the materials used for sodium ion will have higher CO2 emissions. As for the hybrid pack thing, I think it's kind of a BS gimmick like pack swapping. It makes more sense to use one chemistry that caters to the use case. I could be wrong, and my view could evolve, but that's my hot take. It generate unecessary complexity.

@w0ttheh3ll

I agree with your take on the hybrid packs. It wouldn't really be one pack from an electrical point of view, more like having two separate batteries with different properties (and different aging behaviour). The power electronics for driving and charging would have to be more complex. Battery management would be difficult. The mechanical engineering of the pack would be a challenge. And, most importantly, the potential benefits are small.

Sodium Ion seems like it's ideal for small cheap commuter EV's - you only really need ~150km range to cover the vast majority of daily commutes / drop kids off / grocery runs, assuming you're charging overnight every night. $50-70/kWh Combined with a high cycle life means these will be winners!

The issue for sodium is by the time it ramps, it will be competing with lifepo4 batteries which will be in the same cost range and take up 2.5 times less volume. The volume needed is huge because a 150 mile range sodium ion battery in a small car wouldn't fit right now at that energy density. Let alone that anyone can easily produce lifepo4 as it won't take any new skills or supply chain. Sodium is likely to be a energy storage only tech which is fine as that is needed.

I imagine one the main factors in the long term viability of any battery chemistry will be its recycability. This will greatly reduce the cost of materials long term and is the only way we can make them sustainable.

Very thorough. Thanks.

Well done Jordan!

beyond excellent video

Loved this video. I didn't know that about volumetric density difference of Sodium ion. I really want to emphasize something you said about how the sodium batteries can't use table salt and that's a big one people miss. Battery grade materials are not the regular materials and take only the most pure and specialy processed forms. This is why nickel is such an issue as many forms of nickel just can't be used. My two cents are that lifepo4 will make sodium less important in the future as by the time sodium is becoming more relevant, the lithium supply will be becoming less constrained and prices will come down leading to competitive LiFePO4 prices with what will be a much more mature and probably better tech.

Good video as always. at time 2:07. "The basic assumption for Na is that it is more abundant than Li". While it is more abundant than Li, there is plenty of Li for battery consumption. Yes, there are costs associated with Li production, and there are costs associated with Na production. But there is sufficient Li for EV batteries so I'm surprised that's the driving force for Na batteries. Maybe the driving force is cost (due to abundance, cost is lower). And I agree it'll probably be used first for energy storage, freeing Li to be used for EVs, except for those markets that want a "low range" around town car as you mentioned.

Could sodium batteries help me ease the drought in the Mountain West? If California got their water from the ocean through desalination, the waste product could be sold to make sodium batteries. Desalination is expensive but if you could sell the ‘waste’ product, it makes the economics better.

Before I watch the video, my previous understanding of the Sodium Ion battery ia that it is much more suited to stationary storage than the Lithium Ion battery. By utiising Sodium for stationary staorage it will allow Lithium to be used for transport where weight and mass becomes a more important issue. Besides which, there will eventually be a far greater requirement for stationary storage batteries than for transport. From this time perspective, the economic numbers will just fall out in the way that Sodium will be the major stationary battery, and Lithium will be best for transport.

I'd be more than ok with a low cost 180 mile EV. Especially if you can charge to 80% in 15 minutes, as CATL is saying. But if Sodium Ion batteries can replace lead acid reliably, then there's a huge market for them in everything from industrial backup batteries through to mobility scooters and golf carts. I mean, if you build out the UK national grid with batteries, it could be 100% renewable energy almost immediately, instead of being around 50% renewable. And energy costs would drop through the floor.

One correction, Li is less abundant than Ni. Ni comprises roughly 90 ppm in the Earths crust, while Li is only 20 ppm. If you have a source to say otherwise I'm interested to see it!

I do think something worth considering is that it will likely be a far easier task environmentally to source sodium than lithium, as it can potentially be extracted from sources such as seawater desalination, taking what would be a waste product and turning it to productive use, and would shorten supply chains which can take the sources in places where people already live.

@TheLimitingFacor Just FYI, on mobile it looks like there is a thin red line along the bottom that KZread uses to indicate that video has already been viewed. My brain didn't even read the title or anything, I just saw the line and didn't read anything else because I assumed I already saw it.

I looked back at the 20:00 mark and if the 226 current and proposed battery factories in China as opposed to 78 in the rest of the world combined, we see who is going to win. The rest of the world is never going to catch up with that advantage. Somewhat scary.

Yeah i think the 'Prussian blue' analogue pathway is the going to be winner in the Sodium ion chemistry battle...

The Ford Mach E base RWD/AWD Trim is now produced with a CATL LFP battery pack, 78 kWh in size (Munro got a pic of the label on the side of the battery), 72 usable. If a sodium Ion battery pack has a roughly 33% higher volumetric energy density than LFP, that means you can theoretically fit a 58.5 kWh sodium battery pack (around 55 usable) in a Ford Mach E, and a 60 kWh sodium pack in the slightly larger Model Y, around 57.5 usable. At the same 160 LFP efficiency level of a Model Y RWD, you can theoretically get 280 WLTP miles of range or 250 EPA Miles in a RWD Model Y with a 60 kWh sodium pack (57.5 usable), or with AWD about 250 WLTP miles or 225 EPA Miles. You're saying that we currently cannot get more than about 180 miles of range using the higher volumetric density of sodium ion. Am I missing anything or does sodium ion actually currently have the capability of 250 EPA Miles?

Off topic but, the elephump in the room is still Tesla's concept of pulling electricity from earth's magnetic core, tested on the Eiffel Tower and Empire State, and crash-tested as the real power source for the Hutchinson field generators that brought the Towers down... Like to challenge someone to expand on that, but don't annoy the elephump 🙂

I think that the more batteries chemistries at potential low cost with similar performance of today LiBS the better! Especially for the huge efforts of decarbonizes grids and electricity productions to increase Renewables. For storage i thinks that this Sodium-Ion are super good, especially at low cost projections of 40-50$/kWh and high cycles life. Enervue with Nickel- H2 cells and 50000 cycles life and potentially lower cost of LFP will be good too.

What is the CATL Qilin battery? Is it truly a rise in efficiency and storage or did they just stack up more battery cells?

The fearless use of heady concepts, like "deus ex machina", in scripts is why I come here. Do you write all your own copy, Jordan?

What is the nova processing method of Li...to get higher efficiency from ore.

Every storage battery for 4-8 hr storage of solar energy using sodium-ion means just that much more lithium available for uses where both gravimetric and volumetric energy density is important because currently there simply isn't enough lithium to support both a fully EV world and the short duration, high cycle storage needs to even out intermittent power sources like wind and solar. So I see LFP for shorter range EVs and sodium-ion for "power walls" to work with residential and small business roof-top solar as well as possibly large battery installations for load leveling and overnight power when intermittent sources like wind and solar get above about 30% of the total grid power. And as a side note, I think relatively low energy density, but relatively high power density along with a long cycle life, like LFP, are the perfect cells for plug in hybrids with a battery pack good for maybe 100 miles that is teamed with an onboard sustainer engine to extend the range to any desired distance by simply refilling the fuel tank for the sustainer. As a power and propulsion engineer, I wouldn't make the engine large enough to meet the total power needs of the vehicle like they are in nearly all of the current PHEVs like the Chevy Volt or Toyota Rav4 Prime. Instead I would size it to produce just enough power to meet the average power needs at a steady highway cruising speed with a little bit of margin. For trips longer than the battery-only range, the sustainer engine would be started at the beginning of the trip and the batteries would be held at around 50% SOC to allow them to operate at peak charge and discharge rate to both provide and absorb power to meet acceleration/hill climbing and regen braking/downhill grade speed control. The advantage over a large stand-along range extender is that the sustainer engine for an average sized car would only need to be 0.5-1.0 liter size class making 25 or so kW of electrical power and so represent less deadweight to get hauled around when the vehicle is running on battery only power. It also means that the sustainer engine could be highly optimized to operate at maximum power at a narrow range of rpms since it would only be driving a generator, not the wheels and so wouldn't need to run at broad range of speeds. This would mean the sustainer would be operating at a thermal efficiency somewhere in the 45%-50% range (www.cnet.com/roadshow/news/nissan-e-power-gasoline-engine-50-percent-thermally-efficient/). Conventional gas engines that are tuned to operate over a broad operating range usually top out at 30% efficiency. But most of the time a large gas engine is operating at the same 25 kW or so, thus at 10%-20% of peak power. At this very low power level the engine is only achieving about 15%-18% thermal efficiency. Thus a sustainer engine optimized to just produce the necessary steady speed cruise power can 3 or more times as efficient. And while the sustainer engine could burn fossil fuels and still dramatically slash total CO2 since most people drive less than 100 miles a day save for a few long distance trips a year and so the large percentage of the total miles driven would be using just the batteries with power coming from the grid. But the fuel used doesn't have to be pumping new CO2 into the atmosphere by using fossil fuels. Instead it could use carbon-neutral manufactured fuel like butanol, a 4 carbon alcohol, made from CO2 captured from the atmosphere, H2 from electrolysis of water, a little additional electric power combined together in the right pressure, temperature and catalysts all driven by electric power coming from wind, solar or other non-CO2 emitting power sources.
