Aluminum Foil for Supercapacitor/Ultracapacitors
Electrostatic capacitance (a representation of the performance of electrolytic capacitors) is directly proportional to the surface area of the capacitor electrode foil, which requires a high bending strength. In order to increase the surface area by tens upon hundreds of times, aluminum foil for capacitors is treated electrochemically. However, while the greater surface area results in improved capacitance, bending strength tends to decrease.
