An important characteristic of liquid fuels are that as you extract the energy from them you reduce the total weight. In particular for flight this helps increase overall range and efficiency.
Batteries weigh the same full or depleted. So after you deplete 50% of your battery power you’re still carrying 100% of the weight.
In cars this is less of an issue. But for planes, where you are defying gravity, it can make a large difference.
