TC: trial condition; NMPD: nanometric porosity density; AA: agglomeration and aggregation; AAAN: approximate average agglomeration number calculated based on the following equation: (1.1)3 × (1 − 0.4) = 0.799; AAPS: approximate average particle size; ECR: electrochemical response; Surface roughness: (real surface area/geometric surface area); Fast: <125 s; ECRK: electrochemical reaction kinetics.
