 Spheridizing. To work in batteries, graphite particles need to be rounded, kind of potato-shaped. You can think of this as problem number one for getting a battery industry off the ground in the U.S. The potato problem. Chinese companies already know how to reshape graphite. But when Westwater Resources first tried it, their particles were too flat. The feedback months later through our battery partners would be, make it more of a sphere. So we'd go back to them again, and they would do it again.
