'The market launch of Siridion® Black marks an important milestone in the strategic development of our portfolio,' said Peter Friesenhahn, Head of Evonik's Silanes Business Line. 'We are strengthening our offering in attractive, technology-driven growth markets and positioning ourselves as an innovation partner for our customers.'

The introduction of the new high-performance material also completes Evonik's range of battery materials: the company already offers cathode active material and fumed metal oxides for the coating of separators.

'Until now, graphite has been used as an anode material in lithium-ion batteries, but batteries with a higher capacity need new materials that also allow faster charging,' said Dr. Björn Borup, who is responsible for the marketing of battery materials in Evonik's Silanes Business Line. 'As an additive, our solution can be quickly integrated into existing anode materials and production processes, and it combines well with other battery materials.'

The powder is produced by gas phase synthesis. It consists of isolated unsintered spherical particles that are a few hundred nanometers in size. Within the amorphous particles, the carbon concentration increases from the inside out. This ensures superior stability. 'In addition, due to the higher carbon content on the surface, the particles are better protected against oxidation and easier to process', said Dr. Julia Lyubina, who is responsible for the development and commercialisation of Siridion® Black.
