CC-BY-NC-ND 4.0. Single-crystal, conventional, and refined polycrystalline (Li [Ni 0.9 Co 0.05 Mn 0.05]O 2) cathodes were prepared, and their performances and capacity fading behaviors in half cells were compared. The rate capability and cycling stability of polycrystalline cathodes are better than those of single-crystal cathodes.

Our results suggest that while single-crystalline materials might have the advantage of longer cycling-stability and will help to increase battery lifetime, the intrinsically low lithium chemical diffusion coefficient of Ni-rich cathode materials will prove to be the limiting factor for the rate capability.
