摘要

采用简单固相法制备K掺杂O3型Na0.9-xKxCu0.22Fe0.30Mn0.48O2 (x=0、0.05、0.1)正极材料,通过X射线衍射仪、扫描电镜、透射电镜及电化学实验,分析和研究材料的结构稳定性和电化学性能。结果表明:K掺杂可增强材料的结构稳定性,同时Na+的扩散速率和材料的电化学可逆性显著提升。K掺杂使O3→P3相变发生得更早更快,有利于提升O3型正极材料的能量效率。O3型Na0.85K0.05Cu0.22Fe0.30Mn0.48O2正极材料具有优异的循环稳定性,在0.5 C倍率下循环150次后容量保持率为88.6%。K掺杂成本低廉、操作简单,有助于推动稳定的高性能钠离子电池的产业化发展。

Abstract

K doped O3-type Na0.9-xKxCu0.22Fe0.30Mn0.48O2 (x=0, 0.05, 0.1) cathode materials were prepared by simple solid phase method. The structural stabilities and electrochemical properties of the materials were analyzed and studied by X-ray diffractometer, scanning electron microscope, transmission electron microscope, and electrochemical experiment. The results show that K doping can enhance the structural stability, the Na+ diffusion rate and electrochemical reversibility are also significantly improved. The O3→P3 phase transition occurs earlier and faster, which has a positive effect on improving the energy efficiency of O3-type cathode materials. The O3-type Na0.85K0.05Cu0.22Fe0.30Mn0.48O2 cathode material possesses excellent cycle stability, which can deliver a capacity retention of 88.6% after 150 cycles at 0.5 C. K doping is low-cost and simple to operate, which can help to promote the industrialization of stable high-performance sodium ion batteries.
