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 (BMS and WBMS) and their precursor slurries and solutions as shown in Fig. 1 a. Both slurries contain % w/w solids, LFP, CB and PVDF in the ratio 83:13:4, in NMP.
