An Effective Mixing for Lithium Ion Battery Slurries

the ball mill mixer had a finite value of around 25 Pa even at t = 10 s. Eventually, after a long period of time, values of G* for the ball mill and the 3D mixers approached each other, while the curve for the Rushton impeller deviated further away from the others. This is consistent with the steady shear viscosity results showed in Figure 12.
