SGL Carbon SE applications

Energy storage is a key topic in terms of sustainable mobility and energy supply. SGL Carbon offers various solutions for the development of energy storage based on specialty graphite. With synthetic graphite as anode material, we already make an important contribution to the higher performance of lithium-ion batteries, while our battery felts and bipolar plates in stationary energy storage devices (so-called redox flow batteries) enable efficient charging and discharging. In addition, our specialty graphite solutions help improve the fast charging capability of lead-acid batteries.

Light-emitting diodes illuminate our everyday life in all colors, and are also efficient and energy saving. The light of a LED is generated in semiconductor connections. Their performance depends crucially on the quality of these semiconductors. This is where our specialty graphite comes into play: isostatic graphite is fundamental for the production of compound semiconductor layers.These are generated in the “hot zone“ under extreme temperatures during the so-called epitaxy, or MOCVD process. The rotating carrier on which the wafers are coated in the reactor, consists of silicon carbide-coated isostatic graphite. Only this very pure, homogeneous graphite meets the high requirements in the coating process.
