Electric Double Layer Capacitors

Electric double-layer capacitors (EDLCs), also called supercapacitors or ultracapacitors, are ultra-capacity energy storage devices designed to provide a significant amount of power in various applications. They feature exceptionally high capacitance values and store energy through the electrostatic separation of charge. An electric double layer capacitor is known for its high-efficiency energy storage and release, as well as quick charging and discharging capabilities. These supercapacitors can deliver quick bursts of energy, making them suitable candidates for applications requiring high power output over short durations.

Advantages of Using Electric Double Layer Capacitors:

Using EDLCs offers numerous benefits to users in terms of:

  • Rapid Charging/Discharging: EDLCs can charge and discharge in seconds.
  • High Power Density: They provide a significant amount of power per unit volume or mass.
  • Durability: Less prone to degradation over time, offering a longer usable life.
  • Maintenance-Free: Require minimal maintenance compared to batteries.
  • Temperature Stability: Perform well under varied temperatures.

Popular Types of EDLCs:

EDLCs can be categorised primarily based on their electrode materials and construction, including: 

  • Symmetrical EDLCs: Use two identical electrodes, typically made of carbon-based materials.
  • Asymmetrical EDLCs: Use two different electrode materials, enhancing energy density by combining battery-type and capacitor-type electrodes.

Typical Applications of EDLCs:

Electric double layer capacitors are integral to advancing technology where high efficiency, longevity, and reliability are crucial. They continue to evolve, finding new applications in both industrial and consumer electronic systems, including: 

  • Energy Harvesting
  • Power Backup
  • Automotive
  • Consumer Electronics
  • Renewable Energy Systems.
