Spoiler alert: prices have dropped like a Tesla''s 0-60 mph time. In 2025, we''re seeing jaw-dropping figures like $0.056/Wh for supercapacitor cells [4] and $0.426/Wh for full systems [8]. But
Supercapacitor A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap
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.
Due to large selection of Li-ion chargers on the market, it seems reasonable to use a Li-ion charger to charge a supercapacitor. A Li-ion charge profile is show in Figure 2-6.
Costs of supercapacitors storing 15-seconds of electricity average $10,000/kWh, but just $40/kW in power terms. Economics are in this model.
OverviewBackgroundHistoryDesignStylesTypesMaterialsElectrical parameters
A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit mass or energy per unit volume than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.
