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.
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.
Despite higher upfront costs ($3,000–$5,000 per kWh for super-capacitors vs. $150–$200 per kWh for lithium batteries), total cost of ownership is becoming a decisive factor. A 2024 analysis by IDTechEx found that hybrid battery-super-capacitor systems in EVs lowered replacement costs by 60% over 10 years.
Ultra-capacitor costs have decreased 18% since 2020, reaching $0.15 per Farad for industrial-grade units. This price trajectory aligns with the 29% CAGR forecast for renewable-focused ultra-capacitor applications between 2024-2030.
