Mesoporous nano-microparticles lithium-rich Zn-doped Li_1.2Mn_0.54Co_0.13Ni_0.13O₂ cathode materials have been synthesized by utilizing the structural characteristics of metal–organic frameworks. The electrochemical performance is improved by the substitution of an appropriate amount of Zn into the layered Li-rich Li_1.2Mn_0.54Ni_0.13Co_0.13O₂ cathode material.
