This is a most excellent place for technology news and articles.
The economics of an undegrading car battery are interesting.
It's looking like these batteries will allow electric cars to be comparable to an ICE car in terms of price and cheaper to run.
So people will buy them as it makes sense. Then run the car until it falls apart then they will have a very large battery effectively for free. Does that get placed in a new car? Converted into home storage? Grid storage? Cheaply recycled?
