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 Grossröhrsdorf 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 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 “SuperBattery”, and that company signed a €1 billion 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 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 raises €41.3 million in equity round

Estonian startup Skeleton Technologies has raised €41.3 million ($48.5 million) in Series D financing round, bringing its total capital raised to over €93 million ($109 million).

Skeleton Technologies raises funds in recent equity round image

New investors include leading European industrial investors and a group of entrepreneurs "that grew payments company Adyen from its inception to successful IPO", according to reports from Skeleton. In addition, all existing investors in the company joined the equity raise: EIT InnoEnergy – early investors in European gigafactory startup Northvolt — FirstFloor Capital, MM Grupp and Harju Elekter.

Skeleton Technologies working on graphene “SuperBattery” for EVs, signs €1 billion LOI with a leading automotive manufacturer

Estonian startup Skeleton Technologies is reportedly developing a graphene-enhanced “SuperBattery” that can be charged in just 15 seconds, and can go through hundreds of thousands of charge-recharge cycles without degrading. It was also reported that Skeleton recently signed a €1 billion letter of intent with a leading automotive manufacturer to bring the technology to market, most likely in 2023 according to Taavi Madiberk, founder and chief executive of Skeleton.

“This will be a key enabler of the energy transition,” says Madiberk. “In most cases we see that batteries are not able to fully replace the older technologies — we still have hybrid vehicles or the need for backup generators.”

Skeleton to supply its graphene superacpacitors to Warsaw's Tram network

Skeleton Technologies, European developer of graphene-based supercapacitors announced that it has signed a large-scale contract with Medcom to deploy its supercapacitors for Warsaw's Tram network.

Skeletons supercapacitor systems are situated onboard trams and provide energy savings by recuperating braking energy and reusing it for acceleration - and significantly decreasing the total energy consumption significantly. The system also protects the grid infrastructure as it shaves power peaks.

Skeleton Technologies' graphene-based supercapacitors to power Škoda trams in Mannheim

Skeleton Technologies, European developer of graphene-based supercapacitors and energy storage systems for transportation and grid applications, will supply supercapacitor systems to Škoda Electric, a traction equipment manufacturer, for 114 trams to be delivered by Škoda Transportation to Mannheim, Heidelberg, and Ludwigshafen in Germany.

The system recuperates the braking energy of the trams and uses it for re-acceleration, saving energy and decreasing costs. Supercapacitors are ideal for this application due to their high efficiency, reliability, and ability to recharge in seconds.

US Navy finds Skeleton's graphene-enhanced supercapacitors outperform competitors for transient load applications

A study led by John Heinzel from the US Naval Surface Warfare Center in Philadelphia, along with researchers at the University of Texas at Arlington, has compared the performance of supercapacitors from four different manufacturers: Maxwell, Ioxus, JM Energy, and Skeleton. Of the four tested, only the Skeleton supercapacitors are graphene-enhanced.

The team studied cells from the four different manufacturers under high pulsed load conditions to measure their power density into low-impedance loads. The researchers found that the Skeleton cell far outperformed the other cells tested, and graphene was mentioned as the probable cause for this efficiency.
