In fact, the nature of electrical energy is simply the possession of and/or the flow of electrons across a body. A circuit circulates positive and negative ions around, as the flowing positive ions keep the negative ones moving and vice versa.
Now in science, an electrode is a solid electric conductor that carries electric current into non-metallic surface, solids liquids or gasses. Assuming Electrode the Pokemon (Voltorb included) have 2 different segments on their bodies representing the negative ion well that is an annode and a positive ion well that is the cathode, their schtick could be having the power to expell electricity regardless of the strength of conduction to the target.
