To obtain higher capacitance, surface area of aluminum foil for electrolytic capacitor increases through the etching process. During the etching process, a DC or AC current is applied to the aluminum foil. This is done in a chloride solution to assist to dissolve the surface.
Aluminum electrolytic capacitors consist of anode aluminum foil formed with aluminum oxide film on the surface to function as the dielectric. The cathode aluminum foil functions as a collector, and the liquid electrolyte functions as the real cathode. The electrolyte is impregnated onto a separator (spacer) paper between both foils.
Eventually, the capacitance of the cathode foil decreases and the capacitance of the capacitor decreases accordingly, as it is a composition of anode and cathode capacitance. Gas generation caused by this electro-chemical reaction makes the internal pressure of the capacitor increase.
The performance of the device is greatly influenced by the purity, surface finishing and hardness of the aluminum metal. Commercial aluminum foils of the same purity and hardness can have different microstructures and surface roughness, resulting in different cycling performance.
When charged aluminum electrolytic capacitor is discharged by shorting the terminals and left open for a while, the voltage between terminals of the capacitor rises again. This increased voltage is called “regeneration voltage”. The mechanism of this phenomenon is explained as follows.
The results show that commercial aluminum foils with the same purity and degree of hardness but with different thicknesses (from 0.025 to 0.1 mm) exhibit different microstructure and surface roughness, which in turn have an impact on the cyclability.
