Skeleton to use EIRICH mixing systems in the production of ultracapacitors

Ultracapacitors are electrochemical capacitors that are used as high-performance energy storage devices. German/Estonian company Skeleton Technologies GmbH is starting production of these ultracapacitors in Grossroehrdorf near Dresden – using mixing technology and systems engineering from EIRICH.

Compared to conventional batteries or rechargeable batteries, ultracapacitors are significantly smaller and can also be recharged very quickly. They exceed the power density of rechargeable batteries of the same weight by a factor of 10 to 100. The ultracapacitors from Skeleton store electrical energy in a double layer made of graphene. They are so efficient, the European Space Agency (ESA) plans to use them already as early as 2018.

Graphene is a modified form of carbon with a two-dimensional structure, in which every carbon atom is surrounded by three further carbon atoms arranged at angles of 120°, resulting in a honeycomb lattice. Production is extremely challenging. This is why, after trials with other suppliers of mixing solutions, Skeleton opted for the mixing and preparation technology from EIRICH. Multiple process steps can be housed in a single unit, and basic raw materials like activated carbon are easy to mix in. In addition, the advantages of the system also result in higher mixing quality and shorter preparation times. As well as a mixer with a high-pressure cleaning device, the scope of delivery also includes dosing and weighing systems and the corresponding process control system. The ATEX-compliant system is due to go live in March 2017.
