Actually that's not strictly true - a class of batteries called fuel cells
could (actually already can) utilize the oxygen in air.
A fuel cell is about as much of a battery as a Honda Generator.
A fuel cell is an electrical generating device. You put fuel and an
oxidizer in and you get power and water out. They store no energy.
