Lithium-Ionen-Batterie-Kathoden-Pulver
Lithium-Ionen-Batterien sind in Elektrofahrzeugen und -speichern, tragbarer Elektronik, medizinischen Geräten, Elektrowerkzeugen und vielen anderen Produkten allgegenwärtig. Die Lieferanten müssen auf diese steigende Nachfrage reagieren, indem sie neue Batteriechemien für eine höhere Energiedichte entwickeln und gleichzeitig die Recyclingbemühungen verstärken und die Batterieproduktion ausweiten. Rollenöfen, die bei hohen Temperaturen arbeiten, sind entscheidend für die Herstellung der Kathodenpulver, die in Lithium-Ionen-Batterien benötigt werden.
Saint-Gobain Performance Ceramics & Refractories bietet eine Reihe von Lösungen für diese wichtige Branche, darunter seine Hexoloy® und Silit® SK Rollen, zukunftsweisende Keramikprodukte für die Anwendung als Brenn- und Setzhilfsmittel.

Material Description and Applications
Versatile Use in RHKs: Hexoloy® and Silit® rollers, along with our saggers, are integral to the operation of roller hearth kilns. These kilns produce a wide range of products, including electronic components and lithium-ion battery materials like cathode active material (CAM). Rollers transport saggers through different kiln zones, ensuring consistent heating and efficient material processing.
Silicon Carbide Rollers: Our rollers, made from high-quality silicon carbide (SiC), are engineered to endure the cyclical loading of saggers at elevated temperatures in corrosive environments. These rollers are designed to meet the stringent demands of roller hearth kiln (RHK) operators, ensuring maximum roller lifespan and minimal deflection. Improper material selection or construction can lead to roller failure and sagger misalignment, causing damage and increased kiln downtime.
Preferred Roller Materials: Silit® SK and Hexoloy® SE rollers from Saint-Gobain Performance Ceramics & Refractories are the top choices for RHKs due to their superior performance and reliability. These rollers can be specified for new kilns, or our engineering team can assist in selecting and supplying replacement rollers for existing kilns.
High-Performance Saggers: Saggers are essential for containing and conveying products through the rapid heating, high-temperature, and corrosive zones of RHKs. Properly designed saggers maintain structural integrity, resist chemical corrosion from lithium precursor species, and optimize thermal transport to the powder.
PowerCeram™ Saggers: Our next-generation PowerCeram™ saggers, made from advanced silicon carbide, enhance kiln capacity, reduce energy consumption, and extend sagger lifecycle. These saggers are customizable to meet specific heat treatment challenges and come in various shapes and sizes to suit different process conditions.

FAQ
What are saggers and rollers used for in roller hearth kilns?
Saggers in roller hearth kilns serve as containers for powder materials, protecting against contamination and ensuring proper sintering. Rollers are used to transport the saggers within the kiln.
What benefits do rollers and saggers offer in producing lithium-ion battery cathode powders?
Saggers and rollers enhance control over the conditions necessary for efficient calcination and sintering. Saggers contain the powders during high-temperature processes, while rollers ensure consistent transportation of the saggers.
What materials are used to create saggers and rollers at Saint-Gobain Refractories?
Saint-Gobain Refractories uses materials such as silicon carbide, Alundum®, Annamullit®, and Mullfrax® for saggers. For rollers, materials include Hexoloy® SE, Silit® SK, and Crystar®. Explore our brochures for more details on our material offerings.
