A lithium battery is normally good for about 1000 charges at normal rates. I wonder how much of their lifespan gets cut with these superchargers. 750 charges maybe.

Most manufacturers are moving to better battery chemistries, the new main stay LiFePo handles it better, and other designs such as solid state batteries are even better.

LFP can easily do 3000.

Not at that charging rate, no matter how modern you chemistry is.

Sure, but say it cuts your charging cycles by 1/2, which reduces the life of your battery say from 1 million miles to 500,000 miles.

The car will fall apart well before then.

Lucid uses LFP's with a 900v arch and fast charger, with a 150k mile 10 or 8 year battery warranty including free replacement at 70% capacity. Must not be too worried. Tesla's LFP's routinely last 300k miles with a slightly slower charger than Lucids.

Uh no. The Lucid Air uses an NMC811 battery pack comprised of Samsung 50G 21700s, and charges at a peak speed of 300kW.

The 900V figure is the max charging voltage.

That's why maximum charge speed is achieved on 800v based systems.

Won't matter if you sell your fucked battery for scrap to offset the cost of a new one. Lithium going to be very expensive soon.

750 charges times 200 miles is 150,000 miles. That sounds reasonable. And you'll probably still have 80% capacity at that point.

At a 1,000 chargers twice a week that means 10 years of battery life ?

Yes about 10 years if you only need to charge it twice a week. I think it depends on where you live, a guy on YouTube lives in the mountains of Idaho and especially in winter his driving range gets cut to less than 100 miles in his Tesla. Some batteries are not as good when it's freezing outside. Also, where he lives the speed limit is 80 mph and the estimated ranges are for cars driving like 55mph. They can be a great short range commuter car in a flat and moderate climate, otherwise I think a hybrid makes a better solution.
