electric circuits
As this is a stationary circuit, as many electrons are flowing out from the cathode into the wire as are flowing back into the anode. Thus at the battery cathode, electrons flow into the wire replacing those that are moved away by the electron current flow in the wire. At the anode, electrons coming from the wire enter the battery.
Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

A battery is an electric component that provides a constant electric potential difference (a fixed voltage) across its terminals.
rf
Radio waves are produced when the electric field rapidly changes: there has to be an alternating current. An electric field spreads out into space. When you change an electric field, the distant parts of it do not change instantly. The change is limited by the speed of light. If you fluctuate the electric field, you therefore create a wave.
