Skeleton Technologies is a developer and manufacturer of high energy and power density ultracapacitors. The company provides green and cost-effective energy storage solutions for the automotive, transportation, industrial and renewable energy markets.
Skeleton Technologies SkelCap line of ultracapacitors are based on patented technologies of ultracapacitor design and advanced nanostructured carbon allowing for higher energy and power density than competitors. The company has devised a process that uses silicon carbide to make what they call "curved graphene".
Skeleton is reportedly working on increasing the manufacturing capacity for the Grossrhrsdorf production facility from half a million to about 1,000,000 supercapacitors per year in 2020. In terms of footprint, the current 3,500 square meters will be double to about 7,000 square meters by 2020.
Following the scale-up, the plan is to implement the next generation cell design, optimized for automated production and cell assembly. Further automation enables scaling up production capacity to 4,000,000 cells in the first phase, and ultimately to 10,000,000 supercapacitors to meet demand from automotive, grid, and transportation.
In 2020 Skeleton Technologies raised 41.3 Euro million ($48.5 million) in Series D financing round, bringing its total capital raised to over $109 million.
In September 2020 it was reported that Skeleton Technologies is developing a graphene-enhanced “SuperBatteryâ€, and that company signed a billion Euro letter of intent with a leading automotive manufacturer to bring the technology to market, most likely in 2023.
In August 2015, Skeleton entered the commercial truck fleet market when it launched a graphene-based device that helps truck drivers start their engines after long periods of inactivity or in cold weather. In July 2016, Skeleton Technologies announced that it will join French firm Flying Whales programme to build a 60-ton Large Capacity Airship, or LCA60T, for the global transport market. In 2020 Skeleton signed a large-scale contract with Medcom to deploy its supercapacitors for Warsaw's Tram network.
In 2019 Skeleton Technologies stated its plan to invest 25 million Euro in its plant located in the German state of Saxony. With this investment, Skeleton aims to expand its research and development as well as scale its production.

Skeleton Technologies secures €108 Million of financing from investors like Siemens and Marubeni
Skeleton Technologies recently closed a €108 million funding round that includes Siemens Financial Services (SFS), Marubeni Corporation and other investors. This funding will accelerate the development of next-generation products and finance the manufacturing expansion for supercapacitors and the company’s new high-power battery technology – the SuperBattery.
Skeleton Technologies’ CEO and Co-Founder, Taavi Madiberk, said: "Securing an investment from one of Europe's largest tech companies is a significant milestone for Skeleton. In addition to SFS’ investment, Siemens is also a key partner, supplier, and customer. Their expertise in industrialization and commercial partnerships will propel our growth and solidify our role in leading the energy transition”.
Skeleton & Martinrea to collaborate on batteries for refuse trucks
It was recently reported that Skeleton Technologies and the Canadian automotive supplier Martinrea International are cooperating to equip refuse collection vehicles for use in Paris and New York with Skeleton’s ‘SuperBattery’ technology.
Martinrea International develops and produces electric vehicle technologies for heavy-duty commercial vehicles through its subsidiary Effenco. The aim of the agreement with the Estonia-based Skeleton is to electrify fleets of refuse collection vehicles in Europe and North America, starting in New York City and Paris, and later to make the solution developed by both companies available worldwide. In autumn 2022, Shell had already become known as the first major customer for the graphene battery solution. Shell wants to use it to create electrification solutions for mining sites.
Skeleton Technologies launches its SuperBattery and unveils Shell as partner
Skeleton Technologies has officially launched its SuperBattery, and unveiled Shell as its partner. Skeleton is joining a Shell-led consortium to offer electrification solutions for mining sites.
SuperBattery is an innovative technology combining the characteristics of supercapacitors and batteries. SuperBattery has been developed to serve the needs of several sectors and is currently being used and/or tested in hybrid and fuel cell EVs, buses, trucks, and charging infrastructure.
Skeleton’s supercapacitors to power CAF’s new metro units in Granada, Spain
Skeleton Technologies has announced that it will supply its 'curved graphene'-enhanced supercapacitors to the metro units that Spanish manufacturer CAF will provide to the city of Granada, Spain.
Headquartered in Donostia - San Sebastian (Spain), the CAF Power & Automation has been working with Skeleton Technologies since last year. Following a successful tender, the Spanish manufacturer has been selected by the Metro de Granada to supply 8 new units for the city's network, which will be added to the 15 previously-delivered units which are
currently in service.
