Energy storage is getting a jolt, and not just from lithium-ion. A new report from Research and Markets projects the global supercapacitors market will grow at a 15.3% compound annual growth rate (CAGR) through 2036, fueled by demand for electrification, renewable integration, and high-power applications.

Supercapacitors—also known as ultracapacitors—sit between conventional capacitors and batteries, delivering instant bursts of power, ultra-fast charging, and cycle lives that can exceed one million charge-discharge cycles. That makes them ideal for short-duration, high-power use cases that traditional batteries struggle with.

Beyond the Car: Supercapacitors’ Expanding Role

Historically, supercapacitors gained traction in automotive and transportation, powering regenerative braking, start-stop systems, and hybrid drivetrains. But the market is shifting. By 2036, the biggest growth is expected in power grids and renewable energy integration, where supercapacitors can provide lightning-fast frequency response and stabilize grids against intermittent solar and wind output.

Other sectors are waking up, too:

• Data centers & semiconductor fabs are exploring supercapacitor-based UPS systems for reliable, low-maintenance backup power.

• Heavy equipment, mining, and industrial automation benefit from rugged performance and temperature resistance.

• Next-gen fields like 6G communications, electric aviation, fusion energy, and defense are investigating ultracapacitors for their mix of high power and reliability.

Technology Race: EDLCs, Hybrids, and Graphene

The report breaks down three key technologies:

• EDLCs (Electric Double-Layer Capacitors): The most mature and commercially viable, especially in automotive and industrial settings.

• Pseudocapacitors: Leveraging fast redox reactions to store more energy.

• Hybrid supercapacitors (like lithium-ion capacitors): Combining high power with moderate energy density for emerging applications.

On the materials side, advances are accelerating. Graphene electrodes are improving conductivity and surface area, MXenes (2D carbides/nitrides) are pushing performance further, and metal-organic frameworks (MOFs) are being explored for radical new electrode designs. Even structural supercapacitors—where the storage device doubles as part of a car or plane’s body—are on the horizon.

Market Dynamics: Asia-Pacific Dominates, But Watch Europe

According to the report, Asia-Pacific leads production and consumption, thanks to China’s manufacturing muscle and Japan’s R&D strength. North America and Europe, meanwhile, are carving niches in high-performance applications, with companies like Skeleton Technologies (graphene) and Maxwell Technologies (Tesla) pushing boundaries.

The global market includes more than 110 active players, from household names like Panasonic, Nippon Chemi-Con, and Kyocera AVX to startups such as Avadain (graphene) and Ligna Energy (bio-based supercapacitors). Consolidation, R&D partnerships, and heavy investment in advanced materials are shaping the competitive landscape.

The Bigger Picture: Electrification’s Unsung Hero

While batteries grab headlines, supercapacitors are becoming essential for a more electrified world. Their ability to deliver power in milliseconds makes them vital for smart grids, EV performance boosts, and resilient backup systems.

The report stresses that success in this market will hinge on balancing power density, energy density, cost, and scalability. As industries chase efficiency and sustainability, supercapacitors could quietly become the glue holding the energy transition together.
