Skeleton Technologies has launched a new range of cylindrical ultracapacitors that offer specific power performance of up to 111 kW/kg, specific energy up to 9.6 Wh/kg, and capacitance up to 4500 farads.

Skeleton hopes that the high energy density achieved by the SkelCap 4500 series will be a good fit for the heavy transportation market, in which weight and space are at a premium.

The European Space Agency recently announced plans to use Skeleton Technologies ultracapacitors, which it expects to lead to significant cost savings by reducing the volume of heavy batteries required for energy storage.

Skeleton Technologies uses a patented material synthesized from inorganic compounds that has curved graphene layers, allowing better conductivity and higher surface area.

“Graphene has long been heralded as a wonder material for a range of applications, including energy storage. However, a mass-market, graphene-based product has been slow to materialize. Our ultracapacitors will be that market breakthrough,” says Skeleton Technologies CEO Taavi Madiberk.

“The ultracapacitor market is dominated by organic precursor carbon from coconut shell. It is the successful development of a graphene-based carbon that is allowing us to set new records for product performance,” says Chief Technology Officer Volker Dudek.

“We have set ourselves an ambitious technology development target of 20 Wh/kg by 2020, which is comparable with battery-level energy density. With the launch of the SkelCap 4500 range we are already halfway towards that goal.”

Skeleton Technologies recently secured €9.8 million in Series B financing from a strategic investor in the electrical equipment market, which it will use to ramp up production.
