| "Sodium-ion is exciting because..." Well it is exciting, but not for the reasons you think. More like a Michael Bay movie exciting...there is nothing practical about this design. Most of the cost will be safety systems designed to prevent the battery from being exciting and even then a crash will likely set them off. Pure Na-ion probably isn't viable and certainly isn't viable in a car. Maybe mixing in some Na into the Li-ion to stretch the small amount of Lithium but even then you are significantly increasing the volatility of the battery. This isn't a practical step, its an act of desperation from people who don't want to admit that large scale electrification is a dumb idea. We electrified everything that made sense to electrify a half century ago. |

People say the same thing about Li-ion batteries yet they have proven to be significantly less likely to catch fire compared to ICE vehicles [1]. > people who don't want to admit that large scale electrification is a dumb idea. We electrified everything that made sense to electrify a half century ago. I'm very curious to hear why you think this. If nothing else, the 'situation' with the Strait of Hormuz would seem to have shown the importance of energy independence achieved through large scale electrification. Individually, I couldn't go back to an ICE car or even garden tools, they're worse in every way. 1. https://www.mynrma.com.au/open-road/advice-and-how-to/unders... |

Isn't the nasty thing about lithium fires not how likely they are, but how difficult they are to put out, as well as how hot they burn? | | |
| ▲ | brudgers 6 hours ago | parent | next [-] | | Yep. Let it burn is currently the high bit of fire fighting protocol for EV fires used by local fire services. | | |
| ▲ | fluoridation 5 hours ago | parent [-] | | It's only a matter of time before an EV catches fire after crashing into a building and a bunch of people die because the fire couldn't be put out. | | |

| ▲ | Toutouxc an hour ago | parent [-] | | I went in and played a few videos. I'm not sure if anything in there is "sobering" to me (as an EV owner), all the incidents that he shows make sense and the physics are easy to understand. He seems to be pretty knowledgeable about battery and EV architecture and the stated facts and numbers seem solid, but it also sounds like he takes great care not to scare away his flock of EV-hating idiots. |

| ▲ | jeremysalwen 9 hours ago | parent | next [-] | | Just because you state your opinion confidently, does not mean you are correct. For example, as of 2024, there are 30 billion kilograms of proven reserves of lithium, more than enough to replace every single one of the 1.5 billion ICE cars in the world with an electric car. Please focus more on getting the facts right, and less on speculating about the character of other commenters in an overemotional manner. | |

Furthermore, the lithium part of a Li-ion battery isn't the flammable part, the electrolyte is. > If you want to replace FF there is exactly one solution, that's nuclear. You're proposing to... replace vehicular internal combustion engines with nuclear reactors? > Stop acting like you care about this issue. You have never cared enough to learn about it, so until you do, stop spreading misinformation about how physics works. It's wild for you, in particular, to take such a weirdly aggressive stance here. Zero basis in reality, just virtue signaling. | |
| ▲ | November_Echo 7 hours ago | parent | prev | next [-] | | > Just like you (at the moment) are acting like you don't care if people die in fires. There is nothing in my comment that could possibly be interpreted as meaning I don't care about people dying in fires. > If you want to replace FF there is exactly one solution, that's nuclear. We're talking about batteries, so I'm not sure how this is relevant unless you want reactors in cars? > Stop acting like you care about this issue. You have never cared enough to learn about it, so until you do, stop spreading misinformation about how physics works. I made a single, sourced, claim in my comment and didn't mention physics once? > Too bad there isn't enough Li for everyone to have one. Could this be why companies are looking at alternatives? Either way, this claim really should be provided with a source. | |

| ▲ | JuniperMesos an hour ago | parent [-] | | I ride an electric scooter to work. An older friend of mine saw this, and reminisced about how he rode a gasoline-powered scooter to work 20 years ago in the early 2000s, and how he had to deal with the fact that it was loud and smelled of gasoline. I'm sure it was possible to buy some kind of electric scooter then, maybe even one that would've worked for his commuting needs. But I'm not surprised that lithium ion battery tech got significantly better over those 20 years, such that when I bought my scooter last year it didn't even occur to me to look and see if there was something gas-powered I could've bought. |
