Questions on NiMH Batteries

Aluminium-ion batteries look promising after the latest break through by Stanford University scientists.
If this makes it to the market it could be a game changer.

Their aluminium-ion battery can be:
- Charged very quickly (around one minute)
- Handle 7500 charge cycles with no loss of capacity
- Can be destroyed/damaged with no risk of fire

However, as others pointed out yesterday when this was reported in The
Register, notice that there's nothing mentioned about its capacity or
energy density. This is odd as these are two of the things that usually
get hyped when a new battery chemistry is developed.

http://en.wikipedia.org/wiki/Aluminium-ion_battery has more info.
Current energy density is much lower, and voltage lower.
