Direct current (DC) electrical power from a battery has no phase reversal of the electron flow in the electrical circuit. Electrons always flow from the negative terminal to the positive terminal of the battery in the wires of the circuit.

In alternating current (AC), there is a periodic reversal of the flow of electrons (e.g. current) through the wires of the circuit. 60 Hertz refers to the frequency of that reversal of flow. 60 Hz is equal to 60 cycles per second. So AC current from your wall socket in the United States is reversing directions 60 times each second. The cycling is caused by design of the generators used in the power plants that produce the electricity. The current (polarity) reverses direction 120 times each second. Twice in each cycle on a 60 Hz system. Once to the positive and then once to the negative in one cycle.
