Skeleton Technologies is a leading developer and manufacturer of advanced energy storage solutions, specializing in supercapacitors and SuperBattery technology. Founded in 2009 in Estonia, the company has established itself as a significant player in the energy storage industry through its innovative Curved Graphene technology. Their solutions serve multiple sectors, including automotive, transportation, grid systems, and industrial applications. The company’s products offer superior energy density and power performance, contributing to reduced CO2 emissions and improved energy efficiency across various industries. With manufacturing facilities in Germany and Estonia, Skeleton Technologies continues to expand its production capacity to meet growing market demands.
Battery Technology
Skeleton Technologies’ product portfolio centers on two main technologies: supercapacitors and SuperBattery. Their SkelCap supercapacitors deliver high power density and minimal equivalent series resistance, providing over one million charge cycles. These devices excel in applications requiring rapid energy storage and release, such as automotive systems, grid stabilization, and industrial machinery.
The company’s SuperBattery technology represents a significant advancement in energy storage. This innovation combines supercapacitor and battery characteristics, achieving charging speeds 100 times faster than traditional lithium-ion batteries while maintaining a lifespan of 50,000 cycles. Notable for its safety features, the SuperBattery operates without cobalt, copper, nickel, or graphite, making it environmentally responsible. The technology proves particularly effective in applications requiring energy storage under 45 minutes, such as hybrid vehicles and fuel cell systems.
Their manufacturing process incorporates proprietary Curved Graphene technology, which enhances both energy density and charging capabilities. This material innovation sets their products apart in terms of performance and efficiency.
Recent Projects
In 2024, Skeleton Technologies invested €33.7 million in developing SuperBattery-based hydrogen technology for transportation applications. The company also formed a strategic partnership with Tinfos AS to introduce energy storage solutions to Norway. Their Leipzig SuperFactory project, designed with Siemens, continues construction and will become the world’s largest supercapacitor production facility. Additionally, they expanded their collaboration with Shell, focusing on electrifying mining operations to reduce carbon emissions.
Investors
Skeleton Technologies has secured over €300 million in funding from prominent investors. Recent investment rounds include participation from Marubeni Corporation, Siemens Financial Services, and the founders of Adyen. The company received significant support from the European Investment Bank and backing from Germany’s Federal Ministry for Economic Affairs and Energy. Additional investors include FirstFloor Capital, Wise co-founder Taavet Hinrikus, and CTEK co-founder Bengt Wahlqvist.
