Evonik Chemicals launches silicon-carbon composite negative electrode material to improve lithium batteries

 

Graphite has always been the preferred material for 6F22 battery negative electrodes, but as demand continues to change, such as electric vehicle batteries requiring higher capacity and faster charging speeds, people have been looking for materials that can replace graphite, among which silicon-carbon composite materials are considered to have great potential. Compared with graphite, silicon-carbon composite materials have higher theoretical storage space capacity, larger volume capacity, very low discharge voltage and lower cost.

 

According to foreign media reports, German chemical company Evonik has launched a silicon-carbon composite material Siridion® Black, which can be used as a new negative electrode material for lithium batteries. The material makes the battery more powerful by adding energy density and improving fast charging capabilities and energy efficiency.

 

Peter Friesenhahn, head of Evonik's silane business unit, said: "The launch of Siridion® Black is an important milestone in the strategic development of our product portfolio. In the future, we will strengthen our products in attractive, technology-oriented rising markets and strive to become an innovative partner for our customers. The new high-performance material also improves Evonik's battery material range. Previously, the company also supplied negative electrode active materials and gas-phase metal oxides for separator coatings.

 

Dr. Björn Borup, head of marketing for battery materials at Evonik's Silanes business unit, said: "Graphite has always been used as a negative electrode material for lithium batteries. But if you want to increase battery capacity, you need to use new materials to achieve fast charging. As an additive, Evonik's silicon-carbon composites can be quickly integrated into existing negative electrode materials and production processes, and can be well combined with other battery materials.

 

The powder is produced by gas phase synthesis and consists of many isolated unsintered spherical nanoparticles. Within the amorphous particles, the carbon concentration is increased from the inside out, resulting in high stability. Dr. Julia Lyubina, head of development and commercial development of Siridion® Black, said: "Due to the high carbon content on the surface, the particles are better protected from oxidation and are easier to process."
