Positive and negative poles of energy storage lithium battery
When the two poles are connected by a wire, electrons flow from the negative pole toward the positive pole. This flow is called an electric current. In a direct current (DC) circuit, one pole is always negative and the other pole is always positive with the electrons only flowing in one direction.
