Hydrothermal Graphite Deposit Ammenable for Commercial Graphene Applications

I have pasted in the slide that Maureen is referencing from the Japanese presentation. I still am not sure what point you are making exactly. This slide to me looks designed to interest battery manufacturers in the Albany graphite. IMHO it shows, maximum density (a good thing), a mean particle size of 18 (pretty much exactly what battery manufacturers use 15-20), an aspect ratio of about 2:1 (which I believe is a positive indicator of the type of crystall structure, again a good thing), highly crystaline hexagonal structure (again a good thing) and lastly a BET of 8 (again this is a typical number for synthetic used in batteries). So I don't see anything bad about this slide. It looks like they were showing that ZEN can provide graphite to meet the specs of battery manufacturers, which normally comes from synthetic production. Maybe I am missing something, but what?
