The effect of ball milling on properties of the electrode can be gauged through rheological characteristics of the slurry. We have measured shear stress, σ, versus shear rate, γ ˙, at steady state for both types of slurries (BM-S and WBM-S) and their precursor slurries and solutions as shown in Fig. 1 a. Both slurries contain 24.1% w/w …
