Kilo Watt hours of course, normally on batteries amp hours are used because of discharge voltage curves but on EVs the traction battery is always measured in kilo Watt hours as the battery management controller takes care of any voltage changes.to keep power delivery constant.

Lithium, Australia is the biggest supplier is a low density metal, it is the cobalt that is in short supply and nickel is very dirty to refine, but other chemistries are being investigated. Sodium ion, Zinc air and Aluminium air which is quiet good but not rechargeable would be an anode change and liquid removal to recharge. So I think hybrids and short range electrics will creep in then in 10 to 20 years electric full range aircraft will start appearing. So as with mobile phones it will take time to be main stream.
