Why do cables and batteries have a positive and a negative side?

Electrons flow out one side (the negative one) and come back in from the other (the positive one). Current is not associated with electron accumulation, but with electron flow. The point of the battery is pushing electrons from the positive to the negative terminal: this pushing requires energy, that is chemically kept in the battery, used to push the electrons that then release it
