摘要

采用Cu部分替代Ni的方法对蜂窝层状Na₃Ni₂SbO₆正极材料进行掺杂改性,得到Na₃Ni_2-_xCu_xSbO₆(x=0、0.2、0.4、0.8)正极材料,利用X射线衍射仪和扫描电镜研究材料的形貌与结构,并测试其电化学性能。结果表明,Cu掺杂可以有效改善Na₃Ni₂SbO₆正极材料的循环稳定性,在0.1 C倍率下循环100圈后,Na₃Ni₂SbO₆的放电比容量仅为39.5 mA∙h/g,而Na₃Ni_1.8Cu_0.2SbO₆材料的放电比容量达到72.3 mA∙h/g。通过理论计算和实验分析发现,Cu(Ⅱ)的引入可有效缩小Na₃Ni₂SbO₆层状正极材料的带隙,降低Na⁺的扩散能垒,提高材料的电子电导和离子扩散速率,并且Cu掺杂可抑制Na₃Ni₂SbO₆正极材料在循环过程中发生不利相变,从而提高材料的循环稳定性和电化学性能。

Abstract

Honeycomb layered Na₃Ni₂SbO₆ cathode materials were doped with Cu instead of Ni to obtain Na₃Ni_2-_xCu_xSbO₆ (x=0, 0.2, 0.4, 0.8) cathode materials. The morphology, structure and electrochemical properties of the materials were investigated by X-ray diffract to meter and scanning electron microscope. The results show that the cycling stability of Na₃Ni₂SbO₆ cathode materials can be greatly enhanced by Cu substitution, i.e. the Cu-doped Na₃Ni_1.8Cu_0.2SbO₆ materials display a discharge capacity of 72.3 mA∙h/g after cycled for 100 cycles at 0.1C rate, while the discharge capacity of pristine Na₃Ni₂SbO₆ cathode is only 39.5 mA∙h/g under the same situation. Through theoretical calculation and experimental analysis, it is found out that the introduction of Cu (Ⅱ) can effectively reduce the band gap of Na₃Ni₂SbO₆ layered cathode materials and the diffusion energy barrier of Na⁺, and improve the electronic conductivity and ion diffusion performance of the cathode materials, and Cu substitution can also inhibit the adverse phase change of Na₃Ni₂SbO₆ cathode materials during the cycle, thus improving the cycle stability and electrochemical performance of the layered cathode materials.
