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.
- Blogsites are treated in the same manner as social media sites. Medium, Blogger, Substack, etc. are not valid news links regardless of who is posting them. Yes, legitimate news sites use Blogging platforms, they also use Twitter, Facebook, and YouTube and we don't allow those links either.
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 OCTOBER 19 2025
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.

EU drops 2035 combustion engine ban as global EV shift faces reset (www.reuters.com)

The European Commission unveiled a plan on Tuesday to drop the EU's effective ban on new combustion-engine cars from 2035 after pressure from the region's auto sector, marking the bloc's biggest retreat from its green policies in recent years.

The move, which still needs approval from EU governments and the European Parliament, would allow continued sales of some non-electric vehicles. Carmakers in regional industrial powerhouse Germany and in Italy had sought easing of the rules.

The EU executive appears to have bowed to calls from carmakers to keep selling plug-in hybrids and range extenders that burn fuel as they struggle to compete against Tesla, opens new tab and Chinese electric vehicle makers.

I am interested in that battery research though, because charge-cycle wise, only lithium iron phosphate subsection of EV battery chemistry would last even near that long. Lithium ion only lasts 500 cycles before degrading to 70% and LiPo is only 1000. My ID4 could do 420 km on a charge, assuming a LiPo composition, that is 420k kilometers, which is a quarter of what you say

Battery cells degrade very different depending on how they are used. The cycles you mention are the typical values for charging up to 100% and then emptying them completely. This isn't how EVs are usually driven. Cells that are only charged to about 80% most of the time live longer. And with large arrays of cells as in an EV battery, the charging electronics also don't just charge and discharge all cells evenly but can optimize for lifetime. Many EVs also don't charge all cells to full when the car says it's at 100% to increase the lifetime (that's why you sometimes see a "net capacity" mentioned, it's the amount of energy the battery management actually allows compared to what the cells could do).

There are also studies that show that typical usage patterns with small charges all the time (from recuperating) and having long rest times (when the car is parked somewhere) results in a much longer lifetime than simulations with constant use had given, e.g. here: https://news.stanford.edu/stories/2024/12/existing-ev-batteries-may-last-up-to-40-longer-than-expected

Battery chemistry is of course also something there is new developments in, for example CATL is starting production of sodium ion batteries, but AFAIK these are more about cost per capacity than lifetime.
