Interface study of ceramic slurries based on PAA binder
PAA binder,as a commonly used surface modifier,plays a crucial role in improving the interface performance of edge ceramic slurries during the electrode coating process in lithium ion batteries.This study aims to investigate the effect of PAA binder on the interface properties of ceramic slurries.Ceramic slurries were prepared by replacing the traditional PVDF(Polyvinylidene Fluoride)binder with PAA binder using the solid-state blending method.The contact angle and rheological properties of the slurries were tested.The results showed that compared to traditional PVDF-based ceramic slurries,the contact angle was reduced to 22.7°,and the viscosity recovery rate of the slurries was≤10%.These findings indicated a significant enhancement in the wetting properties and stability of the ceramic slurries,enabling easier coating on the substrate surface and formation of uniform coatings with the fusion zone of the positive electrode active material.These research results provide an important theoretical foundation for the design and optimization of PAA binder in the preparation and application of ceramic slurries in lithium ion battery electrode coatings.
