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.

The latest Skeleton Technologies graphene news:

Skeleton Technologies to develop new production technology with €51 million support from German government

Skeleton Technologies recently announced plans to develop new production technology and fully automate manufacturing in its Großröhrsdorf factory. The manufacturer of graphene-enhanced supercapacitors has unveiled plans to develop a first-of-its-kind production technology for the manufacturing of its products, following the official support announced by German authorities. These plans include a fully-automated ultracapacitor production line in its Großröhrsdorf factory. The economies of scale provided by this new technology, combined with the use of Skeleton’s patented “curved graphene” material, is expected to dramatically drive the production costs down.

“We are continuously investing in R&D – whether it is improving the performance of our products or the process in which we make those products. The next stage of our production will see an implementation of fully automated Industry 4.0 manufacturing techniques – a first-of-its-kind in the ultracapacitor industry. Coupled with our curved graphene material, we are able to dramatically decrease the cost of ultracapacitors. The ultracapacitor industry is in the same situation as lithium-ion batteries were in 1999, but our advancements in core technology and production capabilities will be able to show a cost reduction faster than for any other energy storage technology. We have a clear road map to lower it by almost 90% after completion of our 5 years project,” says Taavi Madiberk, CEO and co-founder of Skeleton Technologies, in a press release.

Skeleton Technologies to enter Asian automotive market through strategic cooperation with and investment from Marubeni

Skeleton Technologies, Estonia-based manufacturer of graphene-enhanced supercapacitors, and Marubeni Corporation, one of Japan’s largest conglomerates, have signed a strategic cooperation agreement to support commercial scale-up and customer acquisition for Skeleton’s supercapacitors in the Asian automotive sector, with a strong focus on electrified vehicles and hydrogen transportation.

As part of this agreement, Marubeni Corporation also made an equity investment on top of the €41.3 million Series D financing round announced by Skeleton in November 2020. The sum of Marubeni’s investment was not disclosed.

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).

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.
