OpMoSi: Researching future-oriented batteries with novel silicon carbon composite anodes

In the OpMoSi project, a Styrian consortium has come together to develop future-oriented batteries. This constellation results in a unique bundling of competences in the field of lithium-ion batteries in Austria.

VARTA, AVL, MCL and VIRTUAL VEHICLE are combining their excellence and experience for the OpMoSi research project – this will enable cost-effective and resource-saving production of lithium-ion batteries with advanced silicon anodes.

The project aim of OpMoSi is to increase the energy density of cells by about 20 to 30 percent at 1,000 cycles. This will be achieved by using novel “silicon carbon composite anodes”.
Compared to existing technologies, these offer a 20 to 30 percent increase in energy density with the same cycling stability.

In the following video our experts Franz Pichler, Johann Wurzenberger, Christoph Stangl and Brunner Roland explain the OpMoSi project in more detail: https://www.youtube.com/watch?v=7Oy6qj_Cue4

There are also great news from our colleagues at Materials Center Leoben Forschung GmbH: The 1st OpMoSi publication has been published.
An article about the structural and chemical evolution of silicon and the interfacial formation of solid state electrolytes in the cycle.
If you want to dive deeper into the world of leading-edge batteries and see what the latest developments show, the OpMoSi project is happy to provide some research results.
