It’s early, but is this good? “Ni cathode retains 80% capacity after 300 cycles”
I think not.
Nickel is far more recyclable than lithium is. You can recycle it with nearly no loss of quality.

So after a year, they are 20% gone.
After 2 years, I guess, probably about 50% gone.
If that is so great, what about all the current batteries?
Do EV users need to replace them every other year???
300 cycles is less than a year’s use.
The more you drive, the less you can drive.
