This was posted by nicrtson's post#123963 all about one REE element VANADIUM being used in Lithium-Phosphate Batteries. When VANADIUM-Lithium together, the batteries will last 6 times longer. Perfect for electric-vehicles & Space-crafts in the future. So far no other way can beat Vanadium for batteries. Japan knows that. Lets hope RR will show some Vanadium. Thanks for your info Jack, very informative. Have a good weekend.
