Here is a pretty good discussion (if a bit long winded) of battery life in BEVs. It also explains a lot about why batteries in mobile devices have the lifespan they do.
Lithium-ion Battery Degradation

Can't you give us a little summary? We don't all have infinite free time.

Drive less, charge less, last longer.
Basically he said, if you drive anything other than a Leaf, "Don't worry, be happy!"
The useful info starts around 9 minutes in.

He does discuss that there are mechanisms that degrade a battery based on use and mechanisms that degrade a battery based on age. He talks about the age issue very little, but it would not seem to show up in the data much at all. While there may be some degradation with age, the guy with a 36 year old truck with 250,000 miles on it, is the only person in this group who might actually have a real concern. But if he buys a new ICE truck before they stop being made, he can probably be buried with it still in runnable condition... if he can find gas.
Lol, and well said. Not sure how anybody can expand that into some 25 minute viseo.
- Set Playback Speed to 1.5
- Set time to 8:23 Why do Lithium Ion Batteries Lose Capacity
- 14:15 What Makes Degradation Worse
- Lots of complex variables
- Some battery types are better than others
- Batteries wear out, same as engines and other mechanical parts
- Batteries are getting better
That's actually all a Leaf driver would want to know, because if you watch the video, he talks repeatedly how important operation at elevated temperatures is much worse for the battery than operation at 20°C and below. People focus on operation at cold temperatures since it does impact the capacity and range, but operation at elevated temperatures permanently damages the capacity and range. The Leaf has no temperature control, not even a fan, to minimize impacts on the battery. The result is a measurable reduction in the lifespan of the battery in the Leaf. Ask Ed, he'll tell you his Leaf has very little range left.
If you drive a Leaf, you probably want to keep your head in the sand.

- Batteries are getting better
That's sort of like fusion energy is 20 years away.
Cheers
I don't think anybody misses running "portable" electronics off lead acid batteries.
NIMh was a step up, but the energy density of the lithium stuff is ever better. Cordless power tools that work as good or better than corded ones is reality these days.
Batteries have really come a long way in the past 20 years. Things we have now like RC drones are just not possible with lead acid or nickel cadmium batteries, unless a 3 minute flight time is long enough.
Indeed. I don't think that lead-acid batteries could do this trick:

Fusion has fundamental roadblocks that cannot be overcome. The solution to energy is Thorium Molten Salt.
Battery technology is constantly improving. EV performance is already much better than at the beginning, and new materials are showing good promise. A brief search of google and Youtube gives a plethora of new avenues that are starting to pan out. Examples are:
Carbon Nanotube Electrodes Organosilicon electrolyte batteries lithium sulfur sodium batteries Graphene batteries
The top 10 EV battery manufacturers by market share are all headquartered in Asia:
Rank Company 2021 Market Share Country #1 CATL 32.5% China #2 LG Energy Solution 21.5% Korea #3 Panasonic 14.7% Japan #4 BYD 6.9% China #5 Samsung SDI 5.4% Korea #6 SK Innovation 5.1% Korea #7 CALB 2.7% China #8 AESC 2.0% Japan #9 Guoxuan 2.0% China #10 PEVE 1.3% Japan n/a Other 6.1%
With ICE being phased out and the emphasis on EV, the competition to develop improved battery technology is fierce.
Next-generation battery technologies are already being developed by U.S. companies, including Ionic Materials, QuantumScape, Sila Nanotechnologies, Sion Power, and Sionic Energy.
The results are already apparent. CATL released its first-gen sodium-ion battery in July, 2021. Its single-cell energy density can reach 160Wh/Kg with very fast charge times.
EV batteries are already a huge business, and will only grow. We can expect to see development similar to the vacuum tube, transistor, integrated circuit, internet, etc.
Like most things, advancements in technology are strongly correlated to the amount of money that is involved in the marketing and sales of the items enabled by that technology. With literally trillions of dollars being at stake, you will see enormous advancements in EV batteries over the next five and ten years, and probably onward.
I'm just hoping they will make some available as retrofits.
Isn't every vehicle in france on fire?

It looks like this might be an excellent field to get into, if you understand electronics. Excellent growth prospects, assured future, high demand, especially if you can also program. Another field would be Thorium Molten Salt, but that needs a bit more time to mature.
Of course, skip Fusion.
Nope, none that I can see,

Another thing you won't hear from the Woke crowd are the serious environmental impacts from mining lithium. Well, it is BAD!

Bizarre. Flyguy posts link to nonsense from the woke crowd about serious environmental effects of lithium mining, then tells us that they wouldn't tell us about them.
All kinds of mineral extraction do make some kind of mess, but the mining companies can be persuaded to spend some of the money they make from selling the useful part of what they dig up on tidying up after them. We've been mining stuff since stone age, and we've gotten better at making miners clean up after themselves. Flyguy is an ignorant idiot, so he hasn't noticed.
But so is oil production bad - and a conventional car needs to be provided with fuel for its entire life, not just once.

Alas, us homeowner occasional users are better off with the corded ones for (1) always-ready without prior attention to charging, (2) availability of spares in ten years when this battery is not charging, (3) availability on both new and used market, (4) bench space to park chargers.
I've got two-sub-C NiCd battery items, that probably won't ever get new cells (though it might be worthwhile to rebuild 'em with a Lithium 18650 socket).
Hey SNIPPERMAN, did you actually READ the reference? I truly doubt it, being the moron that you are. You didn't dispute a SINGLE thing in that reference, not the amount of water required or the environmental damage that is being created. Are you a TOTAL IDIOT? I would say so.
