Might be a good idea to mention that conventional current is defined as the flow of positive charge, which is why the actual direction of electron (negative) flow opposes conventional current.
If I were to buy an EV I would rather buy one using lead-acid batteries. Even if these only had a range of 60 miles and took 12 hours to charge this would not be a problem for me as 99% of my journeys are less than this both ways. If I wanted to go further than this I would take the train and not have to worry about finding a charging station which would charge me up to 2.5x the normal price for electricity. Lead-acid batteries can be safely and economically recycled, there is no danger of these being banned from car parks or ferries due to fire risk and I would be able to sleep in my bed without having to worry about my car/garage/house catching fire whilst the batteries were charging.
