A substantial quartz crystal to harvest solar energy transfer through to the arc generator would ignite the fuse inside a vacuum chamber, which, in turn, can be released as propulsion as and when required.

A small quibble: The overall electrical generation system must get greener for any battery technology to provide appreciable benefit. Without that, we are just replacing carbon rich primary movers (ICE) with secondary storage for carbon rich primary generation(Coal, Oil, NG, Wood, Biomass), involving additional losses and increasing the carbon footprint for making, maintaining and recycling the secondary storage. In addition, we are concentrating the locations of emission, exacerbating the effects in certain locales.

Thanks for another awesome & informative video topic. I'm looking forward to your new "where are they now" series. Electrification is certainly a critical component of climate restoration efforts, but it's also vitally important that they are enviro-friendly & socially responsible (climate is a symptom of a much wider ecological & biodiversity crises). Different batteries are best suited for different applications and, at the end of the series, it would be great if we could catergorise them into the areas where they are most suited, for example - thermal storage (for industries that use heat or for district heating applications etc) - batteries for the home or small business - batteries for a car, light industrial vehicle, heavy industrial vehicle, light aircraft etc - community battery storage (microgrids) or medium-sized businesses - grid-scale batteries or for large-scale businesses or heavy industries A company in the US (and I'm sure elsewhere too) uses second life EV batteries as grid-scale batteries. This type of "modular" design may also be useful (and cheaper) for micro grids. I am particularly interested in LMBs - Ambri. Their modular design may mean they are suitable for micro-grds and grid-scale batteries? Since the vast majority of people will live in cities by 2050, most climate solutions must come from cities. Energy generation & storage tech - in my opinion - should be located as close to consumers as possible.

@clairecelestin8437 3 місяці тому

If you're referring to the United States, ironically a significant reason why the size of vehicles increased so much was due to the supposedly environmentalist Corporate Average Fuel Economy regulations. These penalize auto makers based on how fuel (in)efficient their new vehicles are. However, CAFE defines different categories of vehicles, and sets different fuel economy expectations for each category. Rather than continue to make small vehicles and make those vehicles more fuel efficient, it's easier for auto makers to simply build vehicles at a larger size so that they're put in a more lenient weight class, thereby avoiding the penalty, without having to solve the harder engineering problems. They then run massive advertising campaigns to the consumers, convincing consumers that light trucks and SUV's are safer, more attractive, etc. Before the law was imposed, the industry in the US would make about 80% cars, 20% light trucks. Now it's like 35% cars, 65% light trucks, and we've ended up burning way more fuel and doing way more damage to the environment than if the law had simply not existed.

@daveduncan2748 3 місяці тому

The biggest problem with Sodium ion (Na+) batteries is that the voltage is a little low over most of the voltage graph for a typical 12V replacement battery. Putting four Na cells in series creates a nominal 12V battery but the voltage is already well under 12V at 50% state of charge (SOC). The energy density isn't great when compared to LiFePO4 (Lithium-iron, or LFP) batteries, let alone NMC Li-ion batteries like those used in most EVs. The cost for Na+ is still higher than those chemistries for now. Presumably, that will drop as production is developed and refined, but bulk Na+ battery availability could free up the constraints on lithium, and might also just drop the prices of LFP and NMC batteries at the same time, keeping them cheaper, and still better, than Na batteries.

@PeterSedesse 3 місяці тому

what you wrote is just another way of saying the density is lower than lithium ion, which is true. I think he mentioned in the video, for most people the goal of sodium isn't in EVs, it is for stationary batteries, that then reduces the demand of lithium so lithium is cheaper for EVs.

@daveduncan2748 3 місяці тому

@@PeterSedesse Nope. The main point is that the voltage vs. SOC curve is too steep in Na+ batteries. This is VERY bad for stationary batteries where the single largest load is usually the inverter. Inverters typically include a low voltage cutoff, and that would mean getting less than half of the theoretical SOC out of the battery, and the rest having a voltage too low to run the inverter. EVs, with their more complex voltage management systems are often better equipped for a voltage curve like that of Na+. But then you might as well go with LFP, which is lighter, cheaper, and already proven.

@michaelharrison1093 3 місяці тому

In the applications where they will be used this makes no real difference. A number of these cells will be stacked in series to create a 400V battery. Hence you might end up using a few more Na ion cells compared to a Li ion battery.

@ozimandia 3 місяці тому

Thanks for the explanation @daveduncan2748, that may represent a challenge for the residential side of things, as the 12V batteries are almost in disuse, most solar for residential are made of 24V ones, anyway, we can use it in home use, but the fact that they can't sustain the voltage when the battery is 50% or less is a challenge. There must be ways to normalize the current, wish us luck! I going to research a bit more about the voltage variation and the stability of residential system using 12V batteries, just in case we, as a society, need to change to a more sustainable batteries for the closer future. And by the way do you know of any use of this technology in the residential sector? I know they are pretty new but, no harm in ask.

YES! Chunkier but cheaper sodium for grid packs, Lithium for EV's. At 22 million tons of lithium reserves and 8kg lithium per EV, that's TWICE the lithium we need.

Thanks for keeping us up to date on this! I looked up "Prussian Blue", mentioned in the Northvolt segment and was surprised to find they literally meant the pigment. I assume Prussian White is a chemical variation. None of this stuff seems really environmentally friendly though. As well as developing these technologies, we probably all ought to plan on reducing our material and energy consumption.

@allangibson8494 3 місяці тому

Prussian Blue is NaFe(Fe(CN)6). Prussian White is Na2Fe(Fe(CN)6). Nickel, Cobalt and Copper substituted variants are also being trialled for better cycle life and storage capacity.

@robblincoln2152 3 місяці тому

It’s always better for the environment to consume less, but comparing sodium chemistries to practically anything else out there, it toxicity is negligible. I think we would be well off putting national policies (primarily tax and federal purchasing policies) into place that favored Sodium batteries DESPITE their lower density BECAUSE of their much much lower toxicity. Don’t know about you, but I don’t need the ridiculously high range which might require the densities afforded by the best lithium chemistries.

@DVul 3 місяці тому

Thank you for the interesting videos, always learn something from your simplified explanations, cheap with low degradation = long service life, sounds perfect for grid based systems, or a cheap (and likely very heavy) ev? as it would likely limit the capacity to 30-40kwh based on size of battery, which is actually a good size to have for city dwellers especially if the degradation is low which means it should last 15yrs before range is an issue, unlike lithium which will typically lose 35% of it's new capacity in 10 years vs. the 5% stated for Na batteries

@rockyallen5092 3 місяці тому

If I understood it correctly, I think you drew the wrong conclusion from that lifecycle carbon emissions report. My takeaway is the the carbon emissions from all of the battery types is similar and such a small part of the lifetime benefit anyway that it is largely irrelevant. The sustainability IS therefore dominated by material availability and other environmental impacts like extraction and disposal which could be much better for Sodium. Similarly, you may be over-pessimistic about their adoption in cars. Some car manufacturers already choose lower performance batteries because of their environmental and safety benefits and their reduced use of scarce minerals. I see no reason why they should not adopt sodium for the same reasons, especially if it's energy density is as you say "similar" and they can make their supply chain shorter and more reliable.

@user72974 3 місяці тому

I also wonder if they may be useful in vehicles that we want to be electrically-powered, where the vehicles will have chances to recharge frequently (so that the low energy density is not a problem). For example, electric buses where every stop has some sort of charging infrastructure. Or where they charge while they lay over at transit hubs.

@nevadaxtube 3 місяці тому

I may be wrong, but I truly believe that battery technology that is being researched and developed now, will change the world in a relatively few years from now. I believe it might be a quantum leap similar in magnitude to the shift from kerosene lanterns and candles to electricity. In spite of the opposition from the fossil fuel industry and their political cronies, the market will demand change.

@JeremiahTownsend 3 місяці тому

Also agree. I started getting into battery technology for home backup use in 2015 and sealed lead acid (SLA) batteries were still the standard due to costs and availability. Then Li-ion prices dropped and became the standard and now is being replaced by LiFo battery technology as the preferred solution for home and EVs. The tech seems to change for the better every five years.

I feel like a lot of people are waiting for that to happen. Hence the downturn of EV sales. That, with people waiting for the NACS changeover, and all the early adopters already have their EVs. People want sodium ion and solid state technology to get into regular production. For vehicles, sodium ion would be best for smaller economy EVs and phevs. Also, it would be very ideal for battery storage for the home as a back up generator. Larger and high performance EVs will be other battery technology. Hopefully that all gets going in the next 2 years which would tie into the NACS changeover, and EV sales will then be huge by 2026.

@jimgraham6722 3 місяці тому

Thanks, Na will definitely be part of the mix but I dont think there is really any risk of lithium shortages, in particular once recycling is fully established. And lets not forget the vast majority of rechargable batteries made today are lead acid. The developers of that technology haven't been standing still. Improved configurations and incorporation of carbon and calcium into that formulation have led to considerable advances in performance and cost.

@alanhat5252 3 місяці тому

The developers of lead-acid batteries have *_almost_* been standing still since well before marketing & lobbying saw off the far superior NiFe chemistry. Various alloys of the lead framework have been in use since plate warping was discovered to be an issue, calcium & manganese being in use from the early days, the all-singing all-dancing spiral cell of 50 years ago was simply a reversion to the original 1859 design though AGM that came with it was new to this chemistry having been adopted from electrolytic capacitors, carbon in the paste has been in use since WWII. The only thing that's genuinely new is graphene but that's simply used like any other carbon additive, it's just a little more effective. Obviously marketing will tell you a completely different story but even that isn't new, it was marketing that saw off NiFe in the early 1900s for domestic use & industrial use in the 1970s.

sodium ion batteries are rolling out way earlier than i thought. About 4 years early. 90% recyclable. No need for nickel or cobolt. Much cheaper and easier access to sodium over lithium. Then charge cycles and battery density ramping up. Li Ion factories easy to convert to Na ION. Reliance in India planning multiple GigaFactories. CATL in china going full speed ahead. Natron is USA have interesting heavy duty batteries for grid storage, or shipping. Low power density. But tens of thousands of duty cycles. Lastly zero chance of thermal runaway. And batteries can be zeroed. So no fire risk from short-circuits if transported.
