    So Syrah knocks one more rumor on the head – the suggestion that the graphite from Balama could not make spherical graphite, and therefore not be used for batteries, because it is not pure enough.

    The interesting point in this announcement is that the spherical graphite product actually appears to be significantly better quality than demanded by the users. Battery storage capacity is roughly proportional to surface area of the flake graphite spheres, so the smaller they are, the better. And because surface area is proportional to the square of the diameter, halving the diameter produces four times the surface area.

    Current automotive battery producers utilise mainly spherical graphite with 90% of the spheres less than 15 microns diameter. The Balama product has 90% of the spheres less than 6.6 microns, which gives more than five times the surface area required for automotive batteries.

    Consumer product batteries require graphite sphere diameters with 90% less than 10 microns. So the Balama product provide a surface area which is more than twice as good as called for by that application.

    The details are nice to know, but they are not the primary issue. What this latest announcement drives home is that Syrah looks like it is planning to aggressively address most, if not all, the major graphite markets. Given that they have a very large resource, and that their operating costs appear to be a fraction of any others which have yet been announced, this sounds a warning bell for companies in the mid to upper production cost range.
