Skeleton Technologies is a Global Cleantech 100 company and a technology leader in high power energy storage for transportation, grid, automotive, and industrial applications.
For us, developing and producing the best energy storage solutions is a means to an end: helping companies to reduce CO2 emissions and save energy.
We work with some of the largest companies in the world from automotive and industrial OEMs to truck fleet operators and aerospace prime contractors. Our products decrease CO2 emissions and fuel consumption, improve power quality, and empower wider electrification of the biggest industries globally.
Our supercapacitor and SuperBattery energy storage technologies, based on patented curved graphene, represent the biggest technological advancement in the industry in the last 20 years and the use of this innovative material provides our products with an unparalleled advantage in power and energy density.
Skeleton Technologies is located in multiple locations: headquarters in Tallinn (Estonia), manufacturings in Markranstädt (Germany) and Varkaus (Finland), materials development in Bitterfeld-Wolfen, several additional locations in Finland (Helsinki and Lappeenranta), and an office in Berlin and first people in Toulouse (France).

Skeleton Technologies is the world’s largest manufacturer of supercapacitors for mission-critical infrastructure and industry, founded in 2009 in Estonia.
Power today is more than electricity — it is national security, digital continuity, and economic resilience.
Skeleton is the Backbone of Power: equipping grids, defense systems, AI data centers, heavy industry, and critical infrastructure with the resilience to withstand surges, instability, and failure. Our Curved Graphene technology sets the global benchmark for energy storage reliability.
Today, Skeleton employs over 300 energy storage experts and produces more than 4 million cells annually at our Leipzig facility. Our technology is central to the global transition to net-zero, providing reliable, high-performance energy storage that strengthens the systems society depends on.
Skeleton is more than a cleantech company. When power fails, critical operations stop — data goes offline, systems crash, economies freeze, lives are at risk. We exist to prevent that in microseconds. When failure is not an option, Skeleton stands as the backbone of mission-critical power.
