Rheological Analysis of Electrode Slurries for Secondary Battery

Abstract

The understanding and optimization of the production process of secondary battery electrodes has been strongly required in the decade. The internal structure of the slurry for electrodes is one of the unknown factors in the process. The current situation about the utilization of rheological analysis for electrode slurries are firstly reviewed. The effect of particle concentration on the viscosity of dense slurries, the concept expressing the viscosity of bimodal slurries, and the significance of viscoelasticity of slurry related to the internal structure are explained. Finally, the rheological analysis of electrode slurries of LiB anode and cathode are demonstrated.
