E+H digital electrodes are components in electronic or electrical devices and equipment, used as the two ends for inputting or outputting current in a conductive medium (solid, gas, vacuum, or electrolyte solution). The electrode that inputs current is called the anode or positive electrode, and the electrode that outputs current is called the cathode or negative electrode. Electrodes come in various types, such as cathodes, anodes, welding electrodes, and electric furnace electrodes.

In a battery, an electrode generally refers to the position where a redox reaction occurs with the electrolyte solution. Electrodes are positive and negative; generally, the positive electrode is the cathode, gaining electrons and undergoing a reduction reaction, while the negative electrode is the anode, losing electrons and undergoing an oxidation reaction. Electrodes can be metallic or non-metallic; as long as they can exchange electrons with the electrolyte solution, they become electrodes.

The concept of E+H digital electrodes was proposed by M. Faraday in 1834 after conducting systematic electrolysis experiments. Originally, it only referred to the metal rod inserted into the electrolyte that constitutes the battery. A battery is composed of a series of interconnected phases. One end of the electrode is an electronic conductor—a metal (including graphite) or a semiconductor—and the other end must be an ionic conductor—an electrolyte (specifically referring to the electrolyte solution, also known as "electrolyte" or "electrolyte"). A simple electrode should include two phases and one phase interface, i.e., [metal|electrolyte]. Electrodes defined above are also called "half-cells."

E+H digital electrodes are complex. Some are named according to the metal part of the electrode, such as copper electrodes and platinum electrodes; some are named according to the characteristic substances in the redox pair of electrode activity, such as calomel electrodes and hydrogen electrodes; some are named according to the shape of the metal part of the electrode, such as dropping mercury electrodes and rotating electrodes; and some are named according to the function of the electrode. These names, such as reference electrode and sodium ion selective electrode (see ion selective electrode), are all conventional.

E+H digital electrodes are usually marked with a "+" symbol on the battery, which is the positive terminal, and a "-" symbol on the other end, which is the negative terminal. Also, only the positive terminal has a "+" symbol on the battery; the negative terminal does not. Color can also represent positive and negative electrodes: red represents the positive electrode, and black represents the negative electrode.

E+H digital electrodes: Any metal in contact with the electrolyte will generate a potential, which is the most important characteristic property of an electrode.

If there is a rapid electron exchange between a single redox pair at the electrode interface, i.e., a single electrode reaction with a large exchange current (see overpotential transition), this electrode can quickly establish electrochemical equilibrium and is called a reversible electrode. The potential energy of a reversible electrode remains stable for a long period, has greater resistance to interference, and can be measured accurately. It is an essential component of reversible batteries and a core component of potentiometric measurement devices, with significant practical value. Reversible electrodes include the following types:

① Metal electrodes, such as copper electrodes (Figure 2), characterized by the ability of redox pairs to transition across the phase interface.

② Redox electrodes, such as Pt|Fe, Fe electrode (Figure 3), Pt|Mn, MnO, H electrode, etc. Its redox pair cannot migrate across the electrode phase interface. The platinum (Pt) in the electrode only indicates that the electrode metal is inert; it merely provides a site for electron exchange. In practical applications, any inert metal can be used.

③ Gas electrode: This is a redox electrode where one component of the redox pair is a gas (Figure 4), such as the hydrogen electrode (Pt|H2|H) and the chlorine electrode (Pt|Cl2|Cl). To accelerate the reaching of equilibrium, platinum metal needs to be plated with platinum black to increase the surface area and act as an electrocatalyst.
