Fig. 6: Comparison between the as-prepared (top row) and graded-particle (middle row) samples at 50% DoD and 3.75 C discharge.

a, b Comparison of the particle size distribution; c change in interfacial reaction area as a function of the depth in the electrode; d−f comparison of the distribution of the electrolyte concentration; g, h distribution of charge transfer current density and i the resultant voltage vs. capacity curve; j−l comparisons of the SoL. The scale bar in (a) represents 10 μm.
