World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

"The fires then are hotter because there’s a lot more fuel inside an electric car battery because the battery cells are densely packed. It also takes a lot more water to put the fire out."
That's terribly wrong. More accurate: "Because of the materials they are made of, electric car batteries burn hotter and are harder to put out." There's not "more fuel", wth?
I think it's trying to say that the gasoline cars have no fuel in them when transported (thus less fire risk) versus the batteries which can still burn when "empty" (which I doubt they are)
If that's what they meant (and I'm not convinced it is) then it was also worded badly. Now I wonder how cars are transported - if gas/diesel ones are indeed at empty and if EVs are unplugged to reduce any overheating/shorting. For the latter, it's how phones and batteries are shipped, not assembled and low/no charge.
You're being extremely captious from a statement that has a large chance of being made by someone who likely learned English as a secondary language...
I just pointed out it was incorrect. It could be someone who doesn't know English well, or a ChatGPT generated article, or maybe translated badly. That doesn't make it fine from a factual perspective.
I will say that 99% of the posts I tend to see from someone who apologizes for their English being a second language are much better than many Americans who post their ramblings. I don't care much about spelling or grammar, if the point gets across. However in a published article with science facts, I do have a bit higher standard, regardless of the writer or (lack of) editor.
Usually new phones have over half battery. You damage lithium ion batteries when you drain them to 0%, so they wouldn’t ship the cars at no charge either.
Maybe they intended to say that the batteries have higher energy density and, therefor, burn hotter and longer than gasoline?
Trying to dumb down "energy density" to "more fuel"?
The main problem with lithium ion battery fires is that the reaction is self-oxidizing, so you can't put it out by just smothering it. You actually need to cool them down enough so that they don't re-ignite. Plus, once they're damaged, even if you do cool them down enough they're much more likely to short and re-ignite themselves again anyway.
Consider the "fire triangle" - fire needs three things: fuel, oxygen, and heat. With, for example, gasoline fires you can take away either oxygen OR heat to extinguish them, but with lithium-ion battery fires you have to take away the heat to extinguish them.
Fun fact: most gasoline car fires are started by electrical issues. Mechanical fuel pumps died out with the carburetor, just about every car made has hot wires going to the gas tank. The conflagration is completely fueled by gasoline though. Diesel is pretty hard to ignite, you can toss a burning match into a pool of diesel and the match will go out. But once ignited it'll burn like a champ.
There is the problem of what happens when you mix lithium batteries and water.
And a worse problem when you mix lithium and salt water
They saw it coming, they ignored the safety warning, ship catches fire, tale as old as time.
That's pure lithium in those videos. Lithium-ion batteries have a very small percentage of lithium in them. If batteries reacted like that they'd be a nuclear bomb when firefighters dowse them with tons of water to minimize the heat - the water doesn't put out the fire nor cause more burning, it serves to allow the reaction to complete without burning everything else. This is actually a common technique for many chemical fires, the water is just removing part of the heat in vaporization.
Long term water exposure is bad for them though, but not directly because it starts a fire. Salt water can short the battery out and increase a fire risk though, so that's true enough.
Both li-ion and lithium polymer batteries still have many kilograms of lithium. A lithium-ion battery pack for a single electric car contains about 8 kilograms (kg) of lithium, according to figures from US Department of Energy science and engineering research centre Argonne National Laboratory. It may be a small percentage of the total battery pack and coolant weight, but it's still a lot of extremely explosive metal.
It's (mostly) not metallic lithium though, the clue is in the "ion" part of li-ion. I assume you refuse to put salt on your food for fear that the sodium in it will catch fire?
Lithium hexafluorophosphate, which is used in lithium ion batteries, is not elemental lithium and will not explode or burn when merely exposed to water.

True as it can be.
