Hierarchical porous LiNi_1/3Co_1/3Mn_1/3O₂ with yolk-shell-like architecture as stable cathode material for lithium-ion batteries.

ABSTRACT: The relatively sluggish lithium ion diffusion of LiNi_1/3Co_1/3Mn_1/3O₂ (NCM) is one of the fatal factors which can significantly prevent its widespread usage in high-power applications. In this work, the monodispersed hierarchical porous yolk-shell-like LiNi_1/3Co_1/3Mn_1/3O₂ (YS-NCM) with exposure to {010} electrochemical active facets was successfully synthesized, aiming to elevate the lithium ion diffusion ability and thus to enhance the electrochemical performance. The hierarchical porous nano-/microsphere morphology as well as the voids between the yolk and the shell allow for shortened Li⁺ diffusion pathways, leading to improved Li⁺ diffusion capability. These voids are also benef
