Supercapacitors

The performance of supercapacitors is dominated by design and materials choice. Carbon-based materials for electrodes have dominated in the supercapacitors market for electric double-layer supercapacitors (EDLCs), due to low cost, cycling durability and conductivity, and IDTechEx expects this will continue to be the case in the coming decade.

Join Daniel Parr, Technology Analyst at IDTechEx, on Thursday 25th September 2025 for this deep dive webinar into emerging application spaces for supercapacitors. Choose your preferred time zone - the webinar runs three times during the day.

This new IDTechEx report provides insights into the global supercapacitor market, discussing three broad technology groups and segmented into seven market sectors.

A short (8min) presentation on how "New Materials Make Supercapacitors Better than Batteries", sharing some of the research from the new IDTechEx report, "Supercapacitor Materials and Formats 2020-2040".

The new IDTechEx report, "Supercapacitor Materials and Formats 2020-2040" explains why supercapacitors and their variants still only constitute a modest business.

Vehicles for construction, agriculture and mining CAM have become one industry served by giants such as Caterpillar, CNH Industrial, John Deere and Komatsu but also small businesses making the new requirements such as drone systems and weeding and mine survey robots.

It is nonsense to forecast pure electric cars costing the same as traditional ones, then life continuing much as usual. The up-front price of pure electric cars will be dropping below that of internal combustion engine ones around 2025. The fundamentals are now clear. Short range electric cars will continue to sell badly because of range and financial anxiety: their resale value after three years can be down 80%. 200 miles/ 320 km is the tipping point where resale value can be only 40% down on purchase price. See the IDTechEx report, "Electric Vehicles 2020-2030" for the full picture of 100 categories of electric vehicle EV by land, water and air.

Shortage of lithium-ion batteries is probable. Too few gigafactories. Too many burning batteries: factories shut to sort out their problems. The US-China trade war cuts off materials. Inadequate lithium or cobalt mining.

Is it all about cars and extrapolation? Not anymore. The unique new IDTechEx report, "Lithium-Ion Batteries for Electric Vehicles 2020-2030" avoids mindless extrapolation. It uses fundamentals to predict huge changes in the electric vehicle business and the way these vehicles store electricity.
