I was surprised you didnt explain "hard carbon" which is essentially industrial charcoal. Charcoal is light weight and "hard" because it forms open crystal lattices. Those 3-D lattices can handle the larger sodium ions. Graphite is dense and "soft" because it forms in sheets of 2-D lattices which are densely stacked together, but the sheets are not connected to each other so a lump of graphite is like a stack of paper: heavy and flexible and the sheets can be separated. Those sheets are called graphene. Whereas hard carbon is more like wood: lighter and rigid and full of holes.

@@YounesLayachi Coal is one of the precursers to graphite. It is formed from a slurry of wet anerobic plant matter, from swamp to bog to peat to coal. Different grades of coal have different amounts of impurities (including sulfer and water) but it doesnt really have any structure other than carbon rings in a jumble. Charcoal is plant matter (or organic byproducts) that have been forced to carbonize with heat in an anerobic environment. That heat has removed many impurities and water, but left behind cellular structures. So they are similar in that they begin as organic matter and are approaching a pure carbon state through an oxygen-free process. But they are different in structure, weight, cost, and impurities. As a product of natural processes, coal is unpredictable and can only be mined in certain places. It is 100% a "fossil" resource. Charcoal on the other hand can be produced at the industrial scale, anywhere in the world, for relatively cheap. Charcoal within batteries could even potentially be a viewed as carbon sequestration technology for dealing with organic industrial or agricultural waste.

It bears remembering that as far back as world War One, 'Iron/Saline' batteries were fitted to military vehicles. In those days they were heavier than Lead/Acid batteries, but kept their charge much longer, and were far safer in a battle environment.

The equivalent sodium-ion electrolyte is more stable *because* sodium, being more reactive, clings to its electrolyte more tightly and makes it more difficult to break down, so the sodium-ion electrolyte must get a lot hotter before it will catch on fire.

Essentially you can maximize the efficiency of solar, wind and hydro power if you have batteries, and you can significantly reduce reliance on gas, coal and oil power plants. On top of that, static storage could make fast chargers for cars available in places where it wouldn't be possible otherwise. Like, if you have a village that doesn't have a large enough connection to the grid to support 350KW chargers without blowing the power out, you can add batteries. You trickle charge those batteries during the night, and then when you need a surge of power to charge a car, that surge comes from cheap batteries. That way you don't need to dig up the roads and fit bigger cables into the village. And on top of that, as Simon and David pointed out, you have backup power to consider. I used to work in a massive data center. We pulled so much power from the national grid that when it snowed, it would heat up the pavement into the building so much that the snow would melt in that spot. We had generators the size of houses in the basement for backup, and then batteries on every floor to provide power when the grid went down - just to give us time to start up the generators.

This is untrue, and I believe you believe this because you are uneducated about this specifically. The reason that consumer vehicles and EVs are able to go as fast as they are is because running an engine, or an electric motor, at 100% for extended periods of time is not only extremely inefficient, but also very damaging to the engine/motor. Therefore, in order to improve the reliability, and also the longevity of the engine/motor, it's "ideal operation range" is usually anywhere from only 20-40% of it's 100% capability. This means that, as a consequence, yes, the engine/motor is usually only doing 40-60 MPH of the 160+ MPH it's capable of, therefore only 20-30% of what it's capable of, and that's perfect because that means it's very easy in terms of mechanical load for it to handle. This is simple psychics, and a consequence of creating efficient, reliable, and long-lasting engines and EV motors. If cars were created as you say, with an engine/motor running at 100% capability being only going 60-80 MPH, vehicles would break VERY often.

I am sure a person making Li on battery (Mr. Notgoodenough) would know that you can replace lithium with sodium, its pretty basic chemistry. However, for some reason he went for rare and more expansive lithium, it could be due to higher reactivity of sodium which makes it a huge fire hazard, but in reality it makes no difference. Defective battery would be a fire hazard regardless and that difference doesn't really play a huge role.

This is so important... not for the EV market per say - although cheap cars with a limited autonomy can be made with these, but especially for home use. At my house, I have the capacity to produce around 15 megawatts of energy/year from solar, and need about 6 megawatts of energy/year to be completely energetically independent. Problem is that 66% of the consumption is done during the winter months, when the solar energy production is at it's lowest at ~15% of the yearly production. Now imagine installing 200kw of battery storage at the price of what today costs for around 30kw of storage. That would help equalize my dependence on the grid during wintertime. Imagine also having terawatts of storage connected to the grid itself, in order to equalize production curves from regenerable sources. Imagine electricity stations for EV's, with gigawatts of storage on site ready to fast charge car batteries, connected to fields of solar to keep them topped out.

If we start to use industrial desalination for our water supply, one challenge is properly returning the high salinity water back to the sea responsibly. If we need salt to decompose into sodium then the ejecta from desalination process would benefit from the energy used to supply water by consuming high value (high density) brine from the process.

Some information about this company left out in the video. 1) This company has been acquired by Indian conglomerate Reliance industries. So whatever scaling up and manufacturing they are planning will happen in India in the future. 2) Faradion batteries use Nickel, an element which is more scarce than Lithium. CATL Na-ion batteries on the other hand use no nickel. Perhaps that explains why Faradion is able to achieve higher energy density than CATL?

the volume expansion problem is mainly to do with graphite - the spaces in graphite are not quite large enough to accommodate sodium ions, which are fatter than lithium ions; squeezing sodium into graphite causes the spaces to get "wedged" apart over time.

Never underestimate the power of patent law as a weapon for profitability in companies with big legal clout with well funded lawyers in maintaining stale technology and killing innovation. These patents can also be sold which also continues their invidious clamp on progress even when the initiating company loses interest.

One interesting phenomenon I've noticed for batteries is that portable general-purpose batteries are far more expensive per-kWh than electric car batteries, in spite of being much slower in charge/discharge times. For instance, a 1 kWh battery costs around $1000, and has charge/discharge speeds of only a few kW. Yet, an entire car with a 66 kWh battery and a 150kW maximum discharge rate sells for only around $30,000. This discrepancy is insane, and seems to suggest that automakers have the world's lithium market cornered, leaving everyone else to pay vastly higher prices for what scraps are left. Some of it could also be government incentives that apply on to cars, but not to other battery uses. Hopefully, the availability of alternatives such as sodium will help fix this. It seems utterly ridiculous to be in a world where electric cars are quasi-affordable, yet food trucks have no choice but to run off gasoline generators because the relatively tiny battery that would replace it is cost-prohibitive.
