Air powered car

Electric cars seem like the future but the batteries available just don’t cut it. Lithium is fine for a cell phone or laptop which has been optimized for low power use. No matter what you do a car requires enormous energy to move a 3000lb vehicle hundreds of miles with frequent stops and starts. This means that you need a lot of very expensive lithium batteries and lithium is somewhat rare.
I’ve been thinking of what alternate method could store the power necessary and air pressure seems the most likely. Tata motors has experimented with 4500psi air to drive the pistons of a regular small car. To me this hold the best promise but of course there are a lot of problems to overcome, expanding gasses get cold and this is a significant problem. There’s also the problem of inefficiency in the multiple power transitions from electricity to compressed air to driving the car. If a car could be powered by the compressed air that is compressed by the electricity generated by a solar panels you could have a solar powered car.
