No, I think the energy/volume density is higher also.  The pack I got to 
power my DAT player is of about the same volume as 3 of the  4 AA cells it 
normally takes combined.  The three AA NiCad cells would  provide only 3.6v 
at 1100 mAh.  The Li Ion pack provides 7.2v at 1350 mAh.

As I said, i think the reason there are no AA rechargeable Li Ion 
batteries is that the cell voltage is 3.6 volts and is  dictated by the 
chemistry.  Since an AA is nominally supposed to be 1.5v this would be too 
high.
