This is an interesting discussion with Patil and Ann Sastry.

Patil says compared to '11 Volt, the next gen battery is
- 40% more dense
- half the price
This gives us about $250/kWh for the new cells - since he says packing is 30% of the pack cost - a total cost of $350/kWh. Patil had said a few years back that the '11 Volt cells were $500/kWh.
The new battery would be about 210 Wh/kg ('11 was 150 Wh/kg).
GM would need about $20k of battery (assuming 55kWh) to build their 200 mile BEV (which now needs a new name since their Bolt was suspended since it is taken).
If we assume similar pricing and density for Leaf 2, can the battery fit in Leaf ? A 50kWh battery will be about 25% larger than the current 24kWh battery.
