Electric Double Layer Capacitors (EDLC)

Electric double layer capacitors (EDLCs), sometimes called supercapacitors, are energy storage devices which exist between the traditional electrochemical batteries and capacitors. They combine the advantages of both technologies to offer much higher energy storage capacity than capacitors, while also having higher power density than electrochemical batteries. For this reason, they are increasingly being used in applications which require rapid, high-power charging or discharging, such as in electric vehicles, power tools and portable electronic devices.The PAS311HR-VG1 is an EDLC which offers superior cycle life, energy storage capacity and quick charge/discharge times. It is designed for a wide range of applications requiring high-power output and fast-charging capabilities, including hybrid electric vehicles, renewable energy storage, UPS, and portable electronics.

PAS311HR-VG1 Application Field

The PAS311HR-VG1 is suitable for a wide range of high-power applications which require quick charge and discharge capabilities, including:

• Electric vehicles
• UPS systems
• Electric power tools
• Portable electronics
• Renewable energy storage
• Consumer electronics
• High-speed data communication systems

The PAS311HR-VG1 is an ideal choice for applications which require longer-lasting and higher-performance energy storage solutions. Its superior cycle life and energy storage capacity provide increased system stability and reliability, while its charge/discharge times make it suitable for applications which require rapid charging and discharging.

PAS311HR-VG1 Working Principle

The PAS311HR-VG1 is an electric double layer capacitor which utilizes the re-usable electrical energy stored in the energy layer of two closely spaced flat plates. This electric double layer is formed when electrical charges of opposite polarity are deposited onto the plates. The charges are stored as an electrostatic field between the two plates, in a process known as “electrochemical pseudocapacitance”.The two plates of an EDLC are usually made up of activated carbon and a polymeric or metallic electrolyte. This combination of materials produces equilibrium between the electrostatic field and the electrolyte ions in the solution, which can be used as a source of stored energy.The cycle life of the PAS311HR-VG1 EDLC is much higher than that of a traditional capacitor, making it a superior choice for applications which demand high-power output and repeated charge and discharge. It also offers superior safety when compared to a traditional capacitor.

Conclusion

The PAS311HR-VG1 EDLC offers superior cycle life, energy storage capacity and quick charge/discharge times for a wide range of applications requiring high-power output and fast-charging capabilities, including hybrid electric vehicles, renewable energy storage, UPS, and portable electronics. This makes it an ideal choice for applications which require longer-lasting and higher-performance energy storage solutions.
