What Super6 does

Super6 is an early-stage UK private company (legal entity Super6 Limited, founded 2024, headquartered in London) developing advanced supercapacitors for high-power energy storage applications. The company positions its technology around scalable advanced materials and frames supercapacitors as a foundational layer for next-generation energy systems, with stated applications spanning grid energy storage, transport and mobility, data and digital infrastructure, and industrial and manufacturing use cases.

The single core product line is the company's supercapacitor technology, described in its own materials as leveraging decades of technical expertise in advanced materials. There is no public disclosure of pricing, product specifications, performance benchmarks, manufacturing capacity, patents, or named customers. Distribution is via a direct enterprise sales motion with a stated global scope, supported by email ([email protected]) and a LinkedIn company page (linkedin.com/company/super6-limited); no resellers, integrators, or channel partners are listed.

The business model is not formally disclosed: revenue mechanics, contract structures, unit pricing, and sales cycle are absent from public sources. As of August 2025, the company has closed one disclosed funding round of $250,000 from Norrsken Evolve, operates with 1-10 employees, and shows no public revenue, customer logos, partnerships, awards, or regulatory certifications. The company is therefore best characterized as a pre-revenue deep-tech R&D-stage startup whose commercial model remains unproven.

Direct peers

• Skeleton Technologies: Skeleton Technologies is a European supercapacitor manufacturer (Estonia/Germany) and one of the closest direct comparables to Super6, building advanced supercapacitor cells and modules for grid, transport, and industrial customers. Both target the same high-power storage gap with advanced materials, and compete for the same European OEM and utility design wins.
• Maxwell Technologies (UCAP Power): Maxwell Technologies, now operating as UCAP Power, is a long-established supercapacitor pioneer serving automotive, grid, and industrial markets. It is a direct product-line competitor to Super6 with deep commercial relationships and is the kind of incumbent that Super6 must displace or differentiate against.
• LS Materials (LS Cable & System subsidiary): LS Materials is a Korean manufacturer of supercapacitors (ultracapacitors) targeting EVs, grid, and industrial applications. As an Asian-volume supercapacitor producer, it represents the kind of cost-competitive, scaled manufacturer that Super6 would need to differentiate against in automotive and grid segments.
• JSR Micro (JM Energy): JSR Micro (which acquired JM Energy) is a Japanese advanced materials and supercapacitor company focused on high-performance lithium-ion capacitors and supercapacitors. It is a comparable advanced-materials supercapacitor player with a similar technology profile and serves overlapping grid and industrial customers.
• VINATech: VINATech is a Korean manufacturer of supercapacitors and hybrid capacitors with established global sales into automotive, energy, and industrial markets. It is a directly comparable supercapacitor product competitor and represents the low-cost, high-volume end of the market Super6 would compete in.

Emerging players

• Nanoramic Laboratories: Nanoramic (formerly FastCap) is a US-based advanced materials company commercializing next-generation supercapacitors and thermal management technologies. Like Super6, it is leveraging novel materials (carbon nanotubes) to push supercapacitor performance, making it a directly comparable emerging peer in the same technology lane.
• CAP-XX: CAP-XX is an Australia-listed developer and manufacturer of prismatic supercapacitors for consumer electronics, IoT, and small-form-factor energy storage applications. It is comparable to Super6 in core technology (supercapacitors) but focuses on smaller-format, lower-power use cases rather than grid and EV.

Broad incumbents

• Eaton (supercapacitor / Power Quality division): Eaton is a large diversified industrial manufacturer that produces supercapacitor modules as part of its broader power quality and energy storage portfolio. While not a supercapacitor pure-play, Eaton competes in the same grid, UPS, and industrial power-stability segments that Super6 targets with grid and data center use cases.
• Tesla Energy: Tesla Energy provides grid-scale batteries, Powerwall, and Megapack energy storage systems for grid, commercial, and residential applications. Although it is a battery (not supercapacitor) incumbent, it competes in the same grid-stability and data-center-adjacent energy storage market that Super6 targets and influences customer buying behavior.
• Samsung SDI: Samsung SDI is a major global battery manufacturer with growing energy storage system (ESS) and supercapacitor product lines serving automotive, grid, and industrial customers. As a broad incumbent with R&D and scale in adjacent storage chemistries, it represents both a potential partner/competitor and the kind of well-funded player that defines the competitive landscape Super6 is entering.
