The nights are growing shorter, spring bulbs are out and about and the battery business has not taken a quiet winter! Something we really don’t talk enough about is slurry quality. Electrode slurries need to offer good electrical conductivity to support electrode performance and overall battery energy density and electrochemical performance. While impedance spectroscopy of slurries provides an indication of conductive material dispersion in the slurry after mixing, it does not account for shear-induced changes from the coating process. Simultaneous rheology and electrochemical impedance spectroscopy directly measure shear-induced changes in the microstructure to confirm that the electrically conductive network is maintained in the finished electrode.
