Supercapacitor styles and prices

A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Supercapacitors have charge and discharge times comparable to those of ordinary capacitors.

High-reliability, high-power, ultra-high capacitance energy storage devices. 2.7V high-temperature and humidity supercapacitors, featuring a high energy density of over 4Wh/Kg. Feature a high energy density of over 5Wh/Kg and operate at 2.7V nominal DC voltage. Feature a high energy density of over 5Wh/Kg and operate at 3V nominal DC voltage.

Conventional capacitors store energy through the separation of static charges on their electrodes. In comparison, supercapacitors utilize a unique construction consisting of porous electrodes and an electrolyte to form an electric double layer.

See our guide to supercapacitor applications in electric vehicles to learn more about how these components are revolutionizing automotive systems. Other applications where these capacitors are commonly used include medical devices, portable electronic systems, smart grid systems, wearable electronic systems, and renewable energy systems.

The unique design of supercapacitors allows for rapid charge and discharge cycles. While batteries typically offer higher energy density and longer-term storage, supercapacitors excel in delivering quick bursts of energy. Additionally, these capacitors endure numerous charge/discharge cycles and offer high power density.
