Supercapacitor Technical Guide
Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors. They deliver rapid, reliable bursts of power for
The capex costs of supercapacitors are contrasted with the costs of lithium ion batteries and the costs of flywheels in the chart below. A typical supercapacitor stores about 15 seconds of energy, for a capex cost of $10,000/kWh, but just $40/kW of power.
Supercapacitors below 100 F are widely used in devices needing rapid energy discharge with minimal maintenance. The 100–1,000 F range offers an optimal balance of energy density, power output, and design flexibility, making it suitable for diverse industrial applications.
A typical supercapacitor stores about 15 seconds of energy, for a capex cost of $10,000/kWh, but just $40/kW of power. This is down to very high power density (10-25 kW/kg, 10-25x higher than a lithium ion battery), albeit quite low energy density (2-10 Wh/kg, which is 95-99% below a lithium ion battery).
Furthermore, supercapacitors are being explored for energy storage in stationary applications, such as uninterruptible power supplies (UPS) and industrial automation, where their fast response times and long service life are critical .
