What is the approximate error of a nitrogen physisorption, BET based specific surface area analysis for nano-structured materials with 50-150m2/g?

For the measurement, we weighed sufficient material to reach specific surface area of min 10m2, furthermore we used a high precision scale (d=0.1mg)

How can one distinguish a conversion-type from an alloying type material for the storage of Li or Na ions?

In my opinion this information can only be revealed by following the galvanostatic cycling curve of the material, and trying to see if the material reacts as a whole (alloy) or as different...
