From your article (with bold added by me):

To me, the next generation is something like solid-state batteries with the solid anode, but they’re a long way off. Other things, like sodium-ion batteries, are still on the lab scale and you need to get from lab to research to pilot testing, to cathode testing to battery testing. We’re looking at least 10 more years for that.

Good idea for yourself...Don't invest in anything you really have no idea about...Cobalt is here for many more years and I will have made my money and sold out long before 10 years from now...
