Aluminum Foil for Electrolytic Capacitor

Aluminum Foil for Electrolytic Capacitor

Aluminum foil for electrolytic capacitor is mainly used as a foil for capacitor electrodes. Electrolytic capacitors are formed by winding a layer of anode, a layer of negative electrode, and a layer of paper impregnated with a saturated electrolyte paste. The anode aluminum foil for electrolytic capacitor of the anode adopts aluminum foil which is etched and then anodized, which can also be referred to as a formed foil. For the negative aluminum foil for electrolytic capacitor, an aluminum foil that is only subjected to the etching process and not anodized is used. At this time, the negative foil formed is the lead foil of the cathode. Therefore, it is customary in the capacitor industry to call the negative foil is cathode foil, or corrosion foil. In fact, the negative electrode foil and electrolyte paste with a dense and non-porous Al2O3 aluminumoxide foil on the surface constitute another capacitor, but because the oxide film is thin, its capacitance CC is much larger than that of the anode foil and the electrolyte paste CA, so an increase in surface area means an increase in electrostatic capacity and better performance of the electrolytic capacitor. Therefore, the aluminum foil for electrolytic capacitor plays a very important role as a negative(cathode) electrode material.
