electrolitic

Electrolytic is an adjective relating to electrolytes or to electrolysis. It is used to describe processes, devices, or phenomena that involve the movement of ions in solution under an applied electric field, or components that incorporate electrolytes as part of their function. The term derives from electro- meaning electricity and -lyte from electrolyte or dissolve.

In electrochemistry, an electrolytic cell uses external electrical energy to drive a non-spontaneous redox reaction. Electrical power forces ions to move toward oppositely charged electrodes, producing chemical changes at the electrode surfaces. Common applications include electroplating, electrorefining of metals, and water splitting to produce hydrogen and oxygen.

Electrolytes are substances that conduct electricity when dissolved in water or melted, consisting of ions that migrate under the influence of an electric field. They can be acids, bases, or salts. When used in devices, electrolytes must be compatible with the electrodes and the intended operating conditions. Safety considerations include chemical corrosion, caustic or acidic properties, and potential hazards from hydrogen or oxygen generation in some processes.

In electronics, electrolytic capacitors are a type of polarized capacitor that use an electrolyte as part of the conductive path and a metal oxide dielectric formed by anodization. They offer high capacitance in a compact size but require correct polarity, and they can exhibit higher leakage current and aging-related changes compared with other capacitor types. Common variants include aluminum and tantalum electrolytics, available in liquid or solid electrolyte forms.
