Supercapacitors market seen doubling to $1.26B by 2031

Mordor Intelligence says the global supercapacitors market is set to nearly double from 2026 to 2031 as EVs, renewable energy systems and industrial backup power needs expand. China is expected to remain the largest market, supported by manufacturing strength and government backing.

Why it matters: - Supercapacitors are gaining share as industries look for energy storage that charges quickly, delivers high power and lasts longer than many alternatives. - Demand tied to electric vehicles, renewable energy and backup power systems is expected to keep the market growing through 2031.

What happened: - Mordor Intelligence projects the supercapacitors market will rise from USD 0.62 billion in 2026 to USD 1.26 billion by 2031. - The market forecast implies a 15.11% compound annual growth rate during 2026-2031. - The report says China holds the largest market share. - The release was issued July 7, 2026, from Hyderabad, Telangana, India.

The details: - Supercapacitors are being adopted in electric and hybrid vehicles to complement batteries, support start-stop systems, recover braking energy and deliver instant power. - Renewable energy systems use supercapacitors to stabilize fluctuations, improve grid reliability and support energy management. - Industrial users are deploying them for uninterruptible power supplies, automation, smart meters and backup power. - Consumer electronics makers are exploring supercapacitors for wearables, IoT devices and portable electronics that need rapid charging and longer lifecycles. - The report segments the market by configuration, including electric double-layer capacitors, pseudocapacitors and hybrid supercapacitors. - It also breaks the market down by form factor, mounting type, end-user industry and geography. - End-user categories include consumer electronics, energy and utilities, industrial equipment, automotive and transportation, data centers and telecom, defense and space, medical devices and agri-drones. - Geographic coverage includes the United States, Europe, China, Japan, Korea and rest of Asia-Pacific, and rest of the world. - The report says the market is moderately concentrated and competition centers on energy density, power density, lifecycle durability, manufacturing innovation and partnerships. - Key companies listed include Eaton Corporation PLC, Maxwell Technologies Inc., Skeleton Technologies Inc., Cap-XX Limited and Kyocera Corporation. - The report is available in Japanese, French, German, Spanish and Portuguese via Mordor Intelligence.

Between the lines: - The forecast reflects a broader shift toward electrification and smarter energy infrastructure. - China’s lead suggests manufacturing scale and domestic demand remain major advantages in this market. - Growth across North America and Europe appears tied to clean energy spending, grid upgrades and tighter automotive rules. - Asia-Pacific momentum points to a supply-chain and manufacturing buildout, not just end-market demand.

What's next: - More investment is likely in advanced materials, scalable production and next-generation storage designs. - Supercapacitor suppliers are expected to keep targeting automotive, industrial and grid-scale applications. - Regional growth should continue to track EV adoption, renewable integration and data center power needs.

The bottom line: - Supercapacitors are moving from niche use to broader energy infrastructure adoption, and the market forecast points to sustained double-digit growth through 2031.
