St George combined supercapacitor price

How much does a supercapacitor cost?

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.

How much energy does a supercapacitor store?

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).

Where can I buy supercapacitors & ultracapacitor?

Why are supercapacitors important?

Supercapacitors can also regulate voltage, and buffer against voltage drops very rapidly, with response times in the nanosecond range, which makes them particularly useful for buffering the kinds of transients of AI data-centers. What are the costs of supercapacitors?
