Abstract
The non-polarized geophysical electrode has an electrically conductive metal disk mounted at its bottom opening. A mixture of an adhesive such as epoxy, inorganic binder, or RTV silicone, and fine particles in micron or nano size of graphene, nickel, nanotube, or graphite is applied on the outer bottom surface of the conductive metal disk. A lead wire of the electrode is connected to the inner surface of the conductive metal disk and extends outward through a liquid-tight strain relief mounted at a cap provided at the top of the housing of the electrode.
