I was looking through the Nissan News site and ran across a spec sheet in attached files here:

Doing some quick math, the 24kWh divided by 140 Wh/kg works out to 171 kilograms for the battery or about 377 lbs (I assume that does not include the frame or casing for the pack). However, if you multiply 2.5 kW/kg for power density by 171 kg, it works out to 428kW-- quite a bit "over 90"...
It looks like Nissan's batteries are pretty impressive and are being used fairly conservatively in the LEAF application...
