The energy inside both can’t be reused. Both a gas tank and battery can be refilled.
Gas is just easier to transfer between containers. Electricity needs it be moved inside its container.
Isn’t the whole thing about who owns the tank?
Electricity is incredibly easy to move between containers. That’s how electric cars work.
Making charging faster by removing most of the range (because you have way less volume to use if it’s removable) and making a cheap power source obscenely expensive makes no sense.
