Lithium battery cathode and anode slurries adopt differentiated formulation systems based on material properties, electrochemical working environments and industrial demands. Cathodes use NMP-based PVDF oil-based slurries, while graphite anodes adopt water-based CMC&SBR systems. This scientific matching balances battery stability, manufacturing cost and production applicability.
NMP-PVDF Oil-Based System for Cathodes
Cathode active materials operate under high-voltage and strong oxidation conditions and are highly moisture-sensitive. Water contact will trigger material hydrolysis and structural damage, leading to capacity decay and rising internal resistance, making water-based systems unfit for cathode production.
High-polarity NMP can fully dissolve PVDF to form uniform and stable cathode slurries. After curing, PVDF delivers outstanding oxidation resistance and chemical stability. It tightly binds active materials and conductive particles, stabilizing electrode structure during cycling and resisting electrolyte corrosion, serving as the mature and reliable binder for high-voltage cathodes.
Water-Based CMC-SBR System for Anodes
Graphite anode materials feature stable chemical properties and excellent water compatibility, enabling the application of eco-friendly water-based slurries. The combined CMC and SBR binder system perfectly adapts to anode coating and operating characteristics.
CMC stabilizes slurry rheology to avoid graphite aggregation and ensure uniform coating. SBR provides flexible toughness to accommodate graphite’s slight volume change during lithium cycling. Replacing expensive NMP with water eliminates solvent recovery processes, cutting production costs and carbon emissions for greener manufacturing.
