    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.

      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.

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

        The difference is in what happens if they do catch fire though. ICE fires can be extinguished. Li battery fires are “wait until it burns out”.

        It makes a big difference if your car is on a boat.

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

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

          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.
