The weight matters too. EVs are notoriously heavy. You have to haul around the batteries whether they are full or not.
"However, due to their high production costs, these batteries’ initial application will be limited to the “super premium” EV segment."
This is a regular argument against EVs but its a weak argument in the real world application in the USA at least.
The most popular EV by sales in the USA is the Tesla Model Y with a curb weight of about 4200 lbs.
The most popular vehicle in the USA is (and has been for quite awhile) the Ford F150 Pickup which a curb weight of 4400lbs.
Yes, many of those F150 trucks are used in commercial or heavy duty applications legitimately, However, many are not. The F150 outsold the Tesla model Y by more than 50%. Why is the argument of curb weight only leveled against EVs, the recent addition to the roads, and not giant pickup trucks and SUVs that regularly weigh much more?
.
Personally I like small, lightweight cars because they're fun to drive and somewhat efficient. Obviously the f150 doesn't light my fire in that regard, but the model Y isn't exactly a nimble little thing either. Between weight and annoying tech (screens and driver assist mostly), I'm honestly not interested in modern cars at all
"initial" could very well be the key word here. Same goes with any new technology, including the relatively outdated Chevy Bolt design (which was pretty expensive at launch and is now a dime a dozen)
Solid state batteries are more energy dense, meaning that if all you want is 300 miles of range on a charge (perfectly fine with it's faster charging), then you can have less battery for the same range. Now how much lighter I'm not sure, but it's in the right direction!
