Wondered why carbon coating on nano silicon powderThe powder that was produced by Apollon solar in December for testing prior to HPQ doing it's own samples for delivery had a carbon coating. That was the first I heard of such combination, and I always wondered why. Well, if you look up GRAPHENE as an alternative to graphite for anode material in li-on batteries, you will see the potential there for HPQ formulation. I would call it the majic powder,.. no less!!!!
