RE:Are we at the beginning of a multi decade nickel super cycleThe problem is the more expensive the nickel will get, the more intensively they will search to reduce the amount of nickel in ther battery. The two more important thing about electric vehicle is producing them in a ecofriendly way and reducing the price as much as possible to make them attractive.
Apparently it would be extremely hard to do so, but with the future size of that market, I guess they will probably find a way one day...
