Working Principle
An aluminum electrolytic capacitor consists of two electrodes separated by an electrolyte and an aluminum oxide film. The positive electrode, or anode, is the aluminum foil and the negative electrode is the aluminum oxide film. The electrolyte, usually a solution of water and acid, surrounds the anode and provides the path for current flow. When the capacitor is connected to a source of electricity, ions from the electrolyte react with the aluminum oxide film. This reaction generates a positive charge at the anode, which attracts negative ions from the electrolyte to form an electrical double layer.
The voltage drop on this layer becomes equal to the applied voltage and charge builds up on the capacitor plates, leading to electrical energy storage. This basic principle is fundamentally the same among all types of aluminum electrolytic capacitor. The capacitance of an electrolytic capacitor is directly dependent on its size and material composition, and there are various additional design considerations that can be implemented to further enhance the performance.
