Next-Generation LIB Binder
― An Innovative Material Supporting High-Performance Lithium-Ion Batteries ―
As lithium-ion batteries continue to evolve toward higher capacity, higher output, and faster charging, the next-generation LIB binder was developed to meet these demands.
This is an electrode binder (adhesive material) with new properties that fulfill performance requirements unattainable with conventional materials such as PVDF or CMC/SBR.
Key Features and Highlights
◆ High affinity with high-capacity active materials (Si, Sn, S, etc.)
◆ Compatible with new manufacturing processes such as low-temperature drying and aqueous coating
◆ Significant improvement in cycle life and mechanical stability
Next-generation materials gaining attention
Currently, the following materials are gaining attention as next-generation LIB binders:
