10kWh supercapacitor price

How much does a supercapacitor cost per kWh?

While lithium-ion batteries dominate headlines, supercapacitor cost per kWh has emerged as a critical metric for industries demanding rapid charge-discharge cycles and extreme durability. In 2023, the average supercapacitor energy storage system ranged between $3,000-$5,000 per kWh – significantly higher than traditional batteries.

How much does a supercapacitor energy storage system cost?

In 2023, the average supercapacitor energy storage system ranged between $3,000-$5,000 per kWh – significantly higher than traditional batteries. But why does this gap exist, and when will it close? Unlike batteries that rely on chemical reactions, supercapacitors store energy electrostatically.

How much power does a supercapacitor produce?

2 capacitance of 2000 F/g. 2 supercapacitor anchored on a graphene foam electrode delivered specific capacitance of 502.78 F/g and areal capacitance of 1.11 F/cm 2) leading to a specific energy of 39.28 Wh/kg and specific power of 128.01 kW/kg over 8,000 cycles with constant performance.

Does a supercapacitor earn a 10% IRR?

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). Hence a supercapacitor system earns a 10% IRR if it charges a 6c/kWh spread and charges/discharges around 30,000 times per year.
