ViscoTec introduces ViscoTreat-I Slurry feeding and conditioning system for lithium-ion battery electrode coating

ViscoTec has launched the ViscoTreat-I Slurry, an innovative system designed to enhance the preparation and feeding of electrode coating slurry in lithium-ion battery production. This mobile unit integrates material buffering, conditioning, and pulsation-free delivery, targeting small-scale series manufacturing. The system aims to address a critical challenge in battery electrode coating—maintaining a consistent, pulsation-free feed to prevent coating irregularities that can impair the electrochemical performance of cells. The ViscoTreat-I Slurry operates as an intermediate buffer between the mixing extruder and the coater, ensuring smooth slurry flow throughout the process. It features optional recirculation and inline degassing capabilities, which help maintain slurry homogeneity and quality. The system’s precise feed pump, the vipro-PUMP 500, works alongside the vipro-DRIVE controller to deliver the slurry consistently, compensating for rheological changes that occur during coating. Designed with usability and maintenance in mind, the ViscoTreat-I Slurry boasts a mechanical layout that facilitates easy operator access and thorough cleaning. Components can be quickly disassembled using star knobs, and the container lowers for simpler loading. The materials used are resistant to aggressive solvents, ensuring durability in demanding production environments. Additional features include a sight glass for monitoring slurry levels, an LED light ring to aid visibility in low-light conditions, and a mobile base with locking lift functionality for flexible positioning within a facility. This development by ViscoTec could significantly improve the reliability and quality of lithium-ion battery electrode coatings, particularly in smaller production runs where precision and consistency are paramount. By reducing pulsation and enhancing slurry conditioning, the ViscoTreat-I Slurry may contribute to better battery performance and longer cell life. The system’s mobility and ease of use also suggest potential for broader adoption in research and development settings or pilot production lines.
