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".

The Skeleton Technologies production facility is located in Großröhrsdorf, Germany, but a big part of the raw material R&D and innovation takes place in the Black Magic facility in Bitterfeld, Germany. Within Skeleton Technologies, Black Magic focuses on material development and scaling of the synthesis process for its “curved graphene” material. Then, the black powder from the Bitterfeld production facility is to be delivered to Großröhrsdorf for production of supercapacitor energy storage solutions.

Skeleton Technologies’ production facility in Grossröhrsdorf, Germany, is located in a cluster of high-tech manufacturing companies, in an area known colloquially as Silicon Saxony. In fact, the availability of skilled workforce and existing infrastructure were some of the key reasons behind Skeleton's decision to locate the new production facility in Saxony.

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.

As far as electrode manufacturing capacity goes, already in 2017 Skeleton was producing the equivalent of 2,000,000 supercapacitors worth of electrode, and can easily double production to 4,000,000 cell equivalents.

The custom-design electrode mixing unit in Grossröhrsdorf is currently scaled to about 4,000,000 supercapacitor cells, fully automated, and highly advanced. The unit was designed and developed together with an industry specialist system manufacturer to reach faster cycle times than standard machinery can achieve.

One of the key capabilities Skeleton possesses is laser-welding, which makes it possible to design a huge variety of sizes and shapes for supercapacitor modules. On top of in-house laser-welding, Skeleton also does all module and systems design an assembly in-house.

In August 2016 Skeleton raised €13 million, which brings total financing to €26.7 million. In February 2017 Skeleton received a €15 million loan from the Europrean Investment Bank.

<--break->Skeleton Technologies’ high-performance supercapacitors are set to be launched into orbit as part of a European Space Agency project and are also available as part of a hybrid Unmanned Ground Vehicle (UGV) for defence applications. 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 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 and Sumitomo Corporation Europe sign agreement to distribute graphene-based supercapacitors

Skeleton Technologies has announced the signing of a distribution agreement with Sumitomo Corporation Europe, with the aim of providing energy storage solutions for the rapidly growing hybrid electric and electric vehicle industry.

In electric vehicles, graphene-based supercapacitors can be used in tandem with lithium-ion batteries, doubling the battery lifetime and downsizing the cell receiving the peak power from supercapacitors and the long-term energy from the batteries.

Skeleton uses curved graphene in its new supercapacitor-based energy storage system

Skeleton Technologies has unveiled SkelGrid, an energy storage system for industrial power applications, based on the company's curved graphene supercapacitor technology. The system is meant to ensure reliable power quality in manufacturing plants, data centers, and more.

SkelGrid is said to provide the highest power and energy density on the market in the industry standard electrical cabinet or container format. The SkelGrid product family is based on SkelRack modules, which can be installed in industry standard 19”, 600mm deep cabinets, and in 20 or 40 ft. containers to provide short-term power at the megawatt level. The SkelGrid family has maximum power ratings ranging from 520 kW up to 1500 kW, and as a modular product, its components can be configured according to customers’ needs.

Skeleton Technologies launches graphene-based engine start supercapacitor

Skeleton Technologies, developer and manufacturer of high energy and power density supercapacitors, has announced launching a new graphene-based engine start module to help power heavy industry vehicles in extreme conditions. Called SkelStart Engine Start Module 2.0, it is available in 24V and 12V versions and is based on the graphene-based SkelCap supercapacitors, which Skeleton says provide the highest power and energy density on the market.

The new module’s casing is made of non-flammable material that is resistant to vibration and shock, and is a stud terminal device in BCI Group 31 size. Skeleton states that “SkelStart Engine Start modules are designed to provide reliable engine starting in even the harshest conditions, as well as reduced ongoing costs on maintenance and replacement. Businesses can therefore expect their equipment to work cost effectively year-round, affording them peace of mind.”

Graphene used in a molecule that converts carbon dioxide to carbon monoxide

An international team of scientists has designed a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide. The process includes using a nanographene-rhenium complex connected via an organic compound known as bipyridine to trigger a highly efficient reaction that could someday replace solar cells.

Graphene compound to replace solar cells image

The molecule acts as a two-part system: a nanographene "energy collector" that absorbs energy from sunlight and an atomic rhenium "engine" that produces carbon monoxide. The energy collector drives a flow of electrons to the rhenium atom, which repeatedly binds and converts the normally stable carbon dioxide to carbon monoxide. The idea to link nanographene to the metal arose from earlier efforts to create a more efficient solar cell with the carbon-based material. But this model actually eliminates the solar cells, and uses the light-absorbing quality of nanographene alone to drive the reaction.

Skeleton Technologies receives a €15 million loan for graphene-based supercapacitors development

Skeleton Technologies, developer and manufacturer of high energy and power density supercapacitors, has received €15 million in a loan from the European Investment Bank (EIB), under the European Fund for Strategic Investments (EFSI).

This funding is meant to allow the company to finance the R&D for the further development of its products and systems. Skeleton will use part of the money to invest in an electrode mass-production facility in Dresden, Germany, according to the statement. The loan is stated to be based on company performance and doesn’t dilute the holdings of Skeleton’s founders, according to the EIB.
