When I first read the battery results, I must admit I glazed over and took their word that they were good results. But I thought I'd try and find out what the surface area figure actually means. I'm don't specialise in electrochem, but I have a tech background. I don't know if this has been discussed much, so I'll throw it in the ring.
The surface area (BET) figure of 4.09 m2/g really does look very good. Bearing in mind that low BET is good, this is a graph that appears in a number of lithium ion battery technology texts.

This shows that there's a linear relationship between specific charge loss and specific surface area for different synthetic and natural graphite materials. The thing that jumps out is that 4.09 m2/g is way down compared to other materials, implying that charge loss should also be very low. Nice to see the number in context with others.
Those in the industry would know exactly what the numbers suggest.
