They already are safer than ICE cars.

    honestly the only major safety issues with EVs is tesla specific and their ultra retarded door handle system. Yes lets take a simple mechanical system that has worked great for 200 years and make it an electric button, then hide the real mechanical release in a spot that you can't find when panicked and choking to death on smoke. Great job, so futuristic.

    Bigger issue overall is fire departments dragging their feet on not having the correct gear/training to handle self sustaining lithium fires. Gasoline is easy to suppress and dilute, lithium not so much, since it's difficult to get water directly to the cells to cool them below autoignition point.

    The chevy bolt had a battery fire problem with early models that was pretty bad but they replaced all the batteries in the car and it was fine. We got ours replaced for free which essentially made it new given the batteries are the first major component that needs to be replaced.

    No but I heard about an electric car burning once, and none of my ice cars have ever combusted, so CLEARLY, electrics are deathtraps

    Safer than an explosion-powered car carrying a big tank of gasoline? A bold claim! /s

    Wait, how? Aren't they essentially the same except heavier?

    one sets itself on fire over and over thousand of times a minute, using the explosive force to spin wheels.

    The other doesn't.

    They are dissimilar in this regard.

    I'm not sure I agree, but much of that is coming from their heinous "not ready for real world use" like "autopilot" and "FSD".

    I just don't want to be anywhere near one when a battery's breached. That's when it goes from relatively safe to RUN FOR YOUR LIVES.

    AFAIK sodium chemistry batteries are the worst for mobile applications as they're much less energy dense meaning you'll have a heavier pack that needs to be charged more frequently, though it is cheaper for manufacturers to produce. I recall that these work best for grid power storage where size and weight aren't an issue.

    The packs CATL makes now are 175Whr/kg which is very close to LFP. They're already EV-worthy.

    That's great but emerging technologies are shooting for double or triple that amount, so why switch to something thats just barely reaching the equivalent potential of what's already old news?

    Because it's safer, cheaper and works in cold weather.

    What EVs don't work in cold weather? Cheaper for the manufacturer for sure, and potentially safer though its not as if EV fires are some major epidemic.

    At a significant loss, yes. When it was really cold here that was about 30-40%

    I can live with that, 100miles of range is more than I use day to day, so is 60miles. Winter road trips could be a pain, but that's maybe once a year

    Yeah I'd be happy with a safer battery with a bit less range if it also means it's more consistent in said range between seasons. It's good to know you'll make it to X next city/charger/etc regardless of temperatures

    I imagine vastly lower cost would be one reason. 450km range chargeable in 11 minutes would be enough for a significant proportion of people and likely desirable if the cost is low enough. I don't think it's likely that lithium would match the price/perf ratio of sodium so I think we're likely to see a lot more sodium in applications that don't require the absolute best energy density. So in a way, sodium might be the front runner, ahead of advanced lithium, in terms of what's going to be adopted. 😅

    E: Also we're talking sodium batteries in production. If and when double-triple density lithium or another shows up, it might change the calculus depending on price, safety, etc.

    Not the worst, they are still much better than traditional lead-batteries, but worse than lithium. Cheap, low-range EVs are an option however.

    Other than that, you're right. They are much more useful for grid storage, where energy density is way less important than cost.

    EVs are not the primary application for sodium ion batteries, I dont know why this post is trying to focus on that. The really exciting application is cheap grid-scale energy storage, making renewables even cheaper than they already are.

    Liquid electrolyte turns into a solid insulator when heated. 211Wh/kg very cool

    We've seen articles like this one for at least a decade, and real change has never arrived. Either it's completely poppycock like usual, or prohibitively expensive and borderline UN-craftable outside of a billion dollar lab.

    Don't get too excited.

    Trump's dislike of EVs is causing the US to fall behind technologically in its development.

    Yes my wife has had 2 cars that had a fire. But they could be fixed, mostly new cables.
    Problem with an EV catching fire is that it is hotter more intense and cannot be put out with a fire extinguisher. Even real firefighters can't generally put it out. Pouring water on it makes it worse.

    Yeah, yeah. I have heard of new super batteries for well over a decade now. Nothing ever seems to come of it.

    Not this time. They are already being used. They are not super batterie though and won't to replace Lithium batteries any time soon, but they have their niches.

    The main advantage over Lithium batteries is that sodium is an abundant ressource.
