Search "using microcrystalline graphite in battery anodes" and read some of the material and I think it will answer some of your questions, especially with respect to differences in carbon content etc

The combination with Silicon is an interesting one i think, as Silicon has the ability to significantly increase the energy density, with micorcrystalline graphite providing the stability at a potentially very competitive processing cost. Certainly will be interesting to see what the response is from ANZAPLAN.

There is actually a significant Silica resource near ITM's tenements, just north of Whyalla. So maybe SA should be setting themselves up as a major supplier of advanced battery anode materials. Who knows what could happen if we actually promoted it.

Anyway some very interesting time ahead.
