Ok, you have to pay for sections of this, but a few interesting slides. All li-ion cells use a graphite anode except for the Toshiba (Honda Fit).

Slide 15 talks about the costs, but you see the active anode material section is blocked out.

This cleantech battery business is very secretive as any competitive advantage for a company can mean big bucks! In addition, if Zenyatta's natural graphite proves to be better than synthetic, i'm sure we will see governments and top scientists clamouring to get their hands on the Albany product as well. Could lead to new tech innovation industries for Canada too!

Anyways, i'm still feeling positive about ZEN...must be another down day coming :)
