The Impact of Electrode Particle Size and Shape on Battery Slurry Viscosity

atteries are ubiquitous in modern life and our reliance on them has never been greater. Therefore, ensuring optimum battery performance through manufacturing control is of increasing significance. In previous application notes we have discussed the importance of particle size and carbon microstructure on the manufacture and performance of battery electrodes. Another important factor to consider and control is particle shape since irregular shaped particles can reduce packing density, which affects battery performance. Decreased packing density can also increase the viscosity of the electrode slurry which affects the electrode coating process. In this third application note on batteries, we consider the role of size and shape on the viscosity of the electrode slurry.
