A notebook battery pack will typically have 6, 9, or 12 Li-ion cells, depending on cell size and pack configuration. Very typical configurations would be 3 series x 3 parallel or 4 series x 3 parallel 18650 cylindrical cells.

A high runner model of notebook might run half a million to a million pieces, unless you are one of the top vendors, then maybe a few million. I don't know the size of the total market, but I think something like 20-30M notebooks per year worldwide sounds reasonable. I just don't think your derivation makes sense. Isn't the number of notebooks sold last year available somewhere? It would make a good conservative estimate for next year.
