The uniformity and stability of the slurry greatly affect the consistency and electrochemical performance of the final battery cell. The current method of monitoring slurry only has viscosity parameters, which cannot accurately evaluate the uniformity and stability of its electrical properties.

The Significance of Slurry Resistivity The slurry is an important intermediate product in the production of lithium-ion batteries. The uniformity and stability of the slurry greatly affect the consistency and electrochemical performance of the final battery cell. The current method of monitoring slurry only has viscosity parameters, which cannot accurately evalu- ate the uniformity and stability of its electrical proper- ties.
