Definition: The term "electroionic" is a scientific term that refers to an ionizing agent or agent that acts on atoms, molecules, or ions. It can be used in various fields of science and technology such as chemistry, physics, and biology. In the context of electrochemistry, electroionic agents are substances that are capable of ionization by positive charges (ions) released from a cathode. These agents are often found in solutions or mixtures where they act on the ions present within them
