A wave consists of electromagnetic energy in a reversing field. Also known as alternating current, it flows basck and forth through a conducting medium.
For example: The power coming from a wall outlet is AC. It is continously alternating positive and negative at a certain rate per second (60 in the USA). Radio waves are the same thing, but reverse at a faster rate.
However, energy from a battery is a force- (Electromotive force) and is DC (direct current). A force is potential difference and flows only in one direction. It is not a wave at all.
