Supercapacitor Market Size, Growth & Industry
By form factor, modules commanded 57.8% share of the supercapacitors market in 2024, and packs are forecast to grow at 17.4%
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 are developed within a small industry relative to other types of energy storage, such as batteries. Lithium-ion batteries have become the dominant storage technology for most grid applications through significant investment in innovation and scale-up of deployment, as well as the corresponding increased power densities at less cost.
Supercapacitor design has also been focused on developing micro-supercapacitors for portable applications in miniature devices . There are two main architectures: sandwich-structure and interdigital-structure micro-supercapacitors.
Automotive, renewable energy, consumer electronics, and industrial sectors are the primary users of supercapacitors, with high-power storage and efficiency as key focus areas. Shifts toward electrification, renewable integration, and compact energy solutions directly affect operational performance and cost savings for end users.
