Product & Profit Data Snapshot
Cost, Gross Profit, and Margin
Using a public manufacturer in the supercapacitor field (CAP-XX) as a representative benchmark:
- In the six-month period ending December 31, 2024 (H1 FY2025), CAP-XX reported a gross margin of 35%. From that, gross profit is ~35% of revenue, and cost of goods sold ~65%.
- In full FY2024, CAP-XX had revenue of AUD 4.59 million, cost of sales ~AUD 3.21 million, and gross profit ~AUD 1.38 million, giving a gross margin near 30%.
- The lift in margin in 2025 suggests improved cost control, better mix (higher value designs), and greater scale in thin-format supercapacitors.
These data show the pathway by which manufacturers in flexible EDLCs can reach sustainable profitability, especially as volumes grow.
Recent Highlights & Trends
In February 2025, KYOCERA AVX launched its SpiSCAP (SpiCAT) online simulation tool for supercapacitors, enabling engineers to rapidly evaluate SCC and SCM series devices and select cells/modules optimized for discharge profiles. This is pushing design-in speed for flexible supercapacitor adoption across consumer, telecom, automotive, and industrial sectors.
- A materials breakthrough in 2025 enabled a metal-free thin-film graphene supercapacitor stack, delivering 200 V output from just 3.8 cm³. That paves the way for compact, flexible high-voltage modules in constrained electronics and medical / IoT devices.
- Thin, ultra-compact prismatic supercapacitors are gaining ground in wearables and sensors, where space is at a premium. Manufacturers are emphasizing ultra-thin carbon architectures with low ESR to deliver burst power without bulk.
- In transportation, deployment of supercapacitor systems for catenary-free trams, rapid charging at stops, and energy regeneration continues to validate carbon-based flexible modules in harsh duty cycles.
- On the materials front, carbon plus hybrid materials (e.g. graphene + pseudocapacitive coatings, carbon + MXene, carbon + conductive polymers) are being intensively researched to push energy density without losing power or flexibility.
- Margin recovery is occurring as component costs stabilize, process yields improve, and higher-value designs dominate shipments.
Product Snapshots from Five Leading Companies
Here are five representative products (one per company) with key performance data:

Market Trends
1.Printed & Fiber Architectures Moving to Scale
Manufacturers are migrating from proof-of-concept devices to roll-to-roll printed micro-supercapacitors and fiber/yarn architectures. Printed graphene and MXene inks achieving high areal capacitance (e.g. >100 mF/cm²) are narrowing the gap toward practical adoption in wearables and textiles. Fiber-shaped CNT/carbon structure electrodes allow weaving energy storage directly into clothing, smart fabrics, and flexible consoles.
2. Compact High-Voltage Solutions Enable New Use Cases
Delivering 200 V from a few cubic centimeters via metal-free graphene stacks demonstrates that flexible EDLCs are beginning to encroach on domains that previously required bulky or rigid modules. This opens use cases in small drones, sensors, portable medical devices, and compact autonomous systems.
3. Transportation & Rapid Charging Keep Industrial Pressure
Supercapacitors are still favored in high-power, high-cycle applications like catenary-free tram systems, burst charging at stations, regenerative braking, and buffer storage during transients. Their cycle life and instant response maintain relevance even as batteries improve.
4. Design Tools Accelerate Adoption
KYOCERA AVX’s SpiSCAP tool reduces design friction, letting engineers simulate voltage, current, ESR over time for SCC/SCM series devices. That lowers barrier to integrating flexible supercapacitors into products, shortening prototyping cycles.
5. Hybrid Materials & Hierarchical Carbon Structures Dominate R&D
Pure carbon EDLCs are limited by surface area and ion accessibility. Current research emphasizes hybridizing carbon with pseudocapacitive layers (e.g. transition metal oxides or MXenes), hierarchical porosity engineering, and surface functionalization to raise energy density while retaining power and flexibility.
6. Margin Recovery & Economies of Scale
As volume scales, costs of raw carbon materials, electrolytes, separators, and assembly decline. CAP-XX’s jump from ~30% in FY2024 to 35% gross margin in H1 FY2025 illustrates how mix improvement and scale can restore profitability in this segment.

7. Regionalization and Supply Chain Hedging
Given the risk of 2025 U.S. tariff changes, manufacturers are evaluating dual sourcing and regional manufacturing strategies. Companies are locating assembly nearer to key markets (ASEAN, North America) to insulate margins from cross-border volatility.
