Electrochemistry is characterized as a part of general chemistry that relates to charged ions or macromolecules or particles or solids or liquid drops. Charged ions are found in various other sciences such as physics and biochemistry and geochemistry. However, one finds that electrical charges behave differently when these are situated at or near interfaces. It is thus observed that the ionic atmosphere is many times greater in dilute electrolyte solutions than in concentrated systems. In the case of a battery, one has a positive and a negative electrode as placed in an electrolyte. Electrostatic repulsion is probably a more common mechanism for the stabilization of emulsions and van der Waalsforces than any other force. Many non-aqueous dispersants stabilize dispersions by electrostatic charges. Battery electrochemistry characteristics are mainly based on the principles of electrical double layer on the electrode.
