High Performance Additives for Lithium-ion Batteries

BASF’s strong portfolio of market-leading additives delivers efficient solutions that meet performance requirements in the Battery cell manufacturing industry, we offer additives for cathode, anode layers and separator coating in electrode processing aid in smoother and more efficient battery cell processing.

Our additives consist of dispersing agents that enable a viscosity reduction that increase solid content of cathode slurry and improve batch-to-batch consistency, wetting agents that reduce defects during coating and improve application efficiency, and flexing agents that enhance film flexibility and enable a thicker cathode film.

Features

• Cathode active materials: disperse cathode active materials with a much a narrower particle size distribution
• Anode slurry: improve wetting property of anode slurry and reduce coating defects
• Separator coating: improve dispersion of fillers in separator coating and wetting property to PP/pe film
• Additives for conductive materials: improve dispersion of conductive materials and enhance conductivity of electrode
• All BASF battery additive products have stable electrochemical property

Dispersing Agents

• Improve slurry solid content and stability
• Improve dispersion / milling efficiency, bath to batch consistency
• Enable application of new cathode/anode/conductive materials
• Reduce dosage of conductive materials and improve battery energy density
• Anti-settling

Wetting Agents

• Improve application efficiency
• Pronounced defoaming action in aqueous systems, excellent compatibility and wetting action
• Reduce defects during coating process (crater, thick edge etc.), especially during high-speed process

Flexible Agents

• Enable thicker cathode film
