>> Lets say it’s lithium ion. 720kJ/kg (lead acid is only 100kJ/kg). Gas as you say is 3400kJ/l, 4700kJ/kg. 100 years of development in battery technology, and the smart guys who picked gasoline a century ago still have the most advance electric technology beat by a factor of 6. <<
Ridiculous comparison. You don’t consume ANY Lithium* in a Lithium battery.
(*Well, eventually the battery loses its rechargability, which is one of the cautionary issues about electrical cars and their amazingly expensive batteries. But this is at an infinitessimal consumption rate, if you can even call it consumption.)
Of course you don't. Performance and range are defined by energy density. That's the comparison.
How much weight do you have to carry around to provide the "92kWH."
In fact, batteries are worse than combustible fuels because the "lithium" is not consumed.
But you bring up another good point against batteries...!
As you burn gasoline, the weight of the car goes down, allowing effective increases in effective mileage. As you discharge a battery, battery still weighs the same. Effective energy density of a battery goes toward zero as it runs down, whereas energy density of gasoline or diesel remains constant.
