Four NMC materials are synthesized by co-precipitation. They exhibit a hierarchical architecture made of reasonably spherical agglomerates. One is constituted of flake-shaped, spatially oriented, crystallites that leave large apparent void spaces in the agglomerate, while the other results from the tight agglomeration of micron-sized cuboids. Porous material exhibits the best power performances. It is impossible to identify a geometrical parameter that predict performances, even after achieving the full characterization of the microstructures. Cyclic voltammetry reveals two behaviours depending on the shape of crystallites: processes limited by solid-state diffusion (cuboids) and the ones limited by charge transfer even at high rates (flake...
