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.
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.
They already are safer than ICE cars.
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.
Teslas crash more than any other brand. 3/3 last years.
No shit dude the company owner is a coked up idiot who thinks 64-bit glued together utes are the pinnacle of style
that’s because they’re the bmw of ev’s. A disproportionate amount of assholes drive them.
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
/s
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.
Or inside your garage. Or a parking deck. Or a repair shop.
Liquid electrolyte turns into a solid insulator when heated. 211Wh/kg very cool
Wtf is an ice car?
Internal combustion engine
i see thanks
yeah no those burn down all the time lol
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.
Trump’s dislike of EVs is causing the US to fall behind technologically in its development.
