BOARD MEMBER

Frank Wolf

Frank Wolf is CEO of Obrist Engineering and Co-founder of Obrist Powertrain. Mr Wolf started his career as an engineer with an international automotive supplier group in France. After positions in development in Japan and France, he was working in Spain and the USA with another global player for Thermal Management. In 2002, he joined OBRIST Engineering as General Manager and Partner. Since then, he has help the OBRIST Group to grow the global automotive business and has developed the worldwide sales organisation for both companies with daughter companies in the US and China. Frank Wolf is well connected in the automotive industry and advises Battrion in automotive and business related matters.

STRATEGY ADVISOR

Benedikt Eska

Benedikt Eska studied physics at the Technical University of Munich. He served as COO and CEO in energy related startups. In this function he inter alia prepared an IPO at London Stock Exchange (AIM) and executed a trade sale of another startup to a tier one automotive. In 2009, he founded his consultancy business with focus on strategy development for technology driven companies. In parallel he holds a lectureship for energy technology at the Munich University of Applied Science for three years.

COATING ADVISOR

Peter Schweizer, PhD

Peter Schweizer received his PhD in Mechanical Engineering from ETH in 1979, and he did postdoctoral research in coating flows at the University of Minnesota with Prof. Scriven. Peter then spent 16 years in the photographic industry (Kodak and Ilford) before changing to the supplier side of coating technology, where he worked for 19 years at TSE Troller Schweizer Engineering and Polytype Converting. Since his retirement he offers his expertise in coating and drying technology as CEO of Schweizer Coating Consulting. Peter is co-editor of the book Liquid Film Coating. In 2018 he was elected president of the European Coating Society.

SCIENTIFIC ADVISOR

Prof. Vanessa Wood

Vanessa Wood is a professor in the Department of Information Technology and Electrical Engineering at ETH Zurich, where she heads the Laboratory for Nanoelectronics, which focuses on using advanced analytical techniques to understand electronic and ionic processes in solution-processed systems. She received her PhD in Electrical Engineering from the Massachusetts Institute of Technology.

CEO / PRESIDENT

Martin Ebner, PhD

is Chief Executive Officer, President and co-founder of Battrion. After studying electricial and mechanical engineering at ETH Zurich, he received his PhD from the Laboratory for Nanoelectronics under the supervision of Prof. Vanessa Wood where he analyzed the microstructure of porous lithium ion battery electrodes. As a result of this research, Martin received the ETH Pioneer Fellowship and developed methods to control electrode microstructure to not only increase cell-level energy density and charging rates but also drive down manufacturing costs. This work lead to the founding of the ETH Spin-off Battrion AG.

CHIEF OPERATIONS OFFICER

Max Kory, PhD

is Chief Operations Officer and co-founder at Battrion. He studied chemistry at ETH Zurich and received his PhD in the group of Prof. Dieter Schlüter at the Institute for Polymer Chemistry. During his PhD he developed a short and scalable synthesis of a novel periodic two-dimensional material. As COO of Battrion he is now in charge of operations at Battrion.

CHIEF TECHNOLOGY OFFICER

Deniz Bozyigit, PhD

is Chief Technology Officer and co-founder at Battrion. Deniz studied electrical engineering at ETH and obtained his PhD in the Laboratory for Nanoelectronics. During his PhD he analyzed the physical processes that limit the energy efficiency in nanomaterials used in solar cells and LEDs. Deniz then pursued a postdoctoral fellowship at the MIT in Cambridge, MA, before returning to Switzerland.

Reducing the resistance of the battery leads to lower heat generation during charging and discharging. This decreases the risk for thermal runaways and makes cells with Aligned Graphite® safer. In addition, aligning the graphite particles pushes the onset of lithium plating, a dangerous side process that happens during fast charging to higher charging rates.

The Aligned Graphite® Technology, aligns the graphite particles in the negative electrodes. This shortens the diffusion paths of the lithium-ions and thereby reduces the cell resistance. This has a direct impact on the heat generation within the cell upon charging or discharging. Heat generation can be reduced by up to 40%.

By aligning the graphite particles in the negative electrode the diffusion paths are shortened. This allows for higher charging rates. In fact the Aligned Graphite® Technology can cut charging times in half.

The Aligned Graphite ® Technology can be easily implemented to match production equipment of varying sizes. The Aligned Graphite ® fabrication technology does not reduce production speed. This facilitates scaling.

Battrion’s production process is fully compatible with todays electrode production speeds. In addition, we are working on reaching the production speeds of tomorrow.

Battrion’s Aligned Graphite Technology ® is fully compatible with current cell fabrication processes and materials.

The Aligned Graphite® Technology allows to control the orientation of flake graphite particles. Orienting the flakes vertically leads to short effective lithium transport distances and therefore to very high charging currents without degradation.
