The true EV revolution is the sodium ion battery, because it lays the path for a billion "city car" EVs.<p>In terms of the American market:<p>150 wh/kg sodium ion (which should pack at 90% with Cell-to-Pack since it is much safer than Lithium ion NMC chemistry) should be about a 250-300 mile Toyota Corolla type car.<p>200 wh/kg, which CATL is soon to come, should enable 350-400 mile cars.<p>Sodium Ion cells should be about 40% or less the cost of lithium ion NMC, and I'm guessing even less with really big economies of scale. That should equate to a fundamental price advantage of EV vehicles over ICEs in drivetrain cost, hopefully to the tune of $5000 or so.<p>But what I think the Sodium Ion cell enables is a $10,000 city car of a couple hundred miles of range, which is particularly important to China, India, and heck any urbanized area, plus a whole host of mopeds, kei cars, scooters, etc, all being able to economically drop the ICE, especially the two-stroke variants.<p>I hope to see these enter the lawncare markets too, converting what are now premium/luxury products like eGo which are more expensive than combustion tools, to ones that are cheaper than them fundamentally.<p>The entire tool market is still hideously expensive for extra batteries, it is obvious the companies are profit taking.<p>The only thing better would be Sodium-Sulfur which would hopefully double density, but we shall see.
