An Electric Double Layer Capacitor (EDLC), also known as a supercapacitor or ultracapacitor, is an advanced electrochemical energy storage device. It stores and releases energy based on the electrostatic charge separation at the interface between electrodes and electrolyte.
Unlike traditional batteries, EDLCs do not rely on chemical reactions, allowing for extremely rapid charging and discharging cycles and superior longevity.
Our Electric Double Layer Capacitors are versatile and used extensively across multiple high-demand sectors:
| Surge Voltage | 2.85V |
| Standard Charging Current | 80A |
