Supercapacitors, also called ultracapacitors or double-layered capacitors, are not your standard capacitors. They hold significantly larger amounts of electrical charge, bridging the gap between standard electrolytic capacitors and rechargeable batteries. What sets these capacitors apart is their unique combination of high power density, short charging times, and long cycle life. These electrochemical capacitors come in varied mounting configurations, each with different voltage ratings, making them an indispensable component in various applications requiring efficient charging and discharging cycles.
Materials and Construction of a Supercapacitor
Supercapacitors are built to last. They comprise two porous electrodes immersed in an electrolyte solution, separated by an ion-permeable membrane. The electrodes, typically crafted from activated carbon or other high-surface-area materials, are designed for efficient charge storage, ensuring the reliability and durability of the supercapacitor.
