To enhance the rate capability and cycling stability of the high-voltage cathode material LiNi0.5 Mn1.5O4 (LNMO), a V-Y co-doped LNMO cathode material was synthesized via the polymer soft-template method. The effects of V-Y co-doping on crystal structure, interfacial properties, and electrochemical performance were systematically investigated. The material was characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) among other techniques, and the electrochemical properties were analyzed via galvanostatic charge-discharge, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The results indicate that V-Y co-doping induces the formation of disordered Fd3m phase by effectively regulating LNMO, facilitates the morphology evolution of spinel from regular octahedron to truncated octahedron, and constructs a coherent interface, which significantly enhances the lithium-ion diffusion rate and electronic conductivity. Moreover, V-Y co-doping reduces the Mn3+content, suppresses Jahn-Teller effect and side reactions at the electrode/electrolyte interface, thereby enhancing the interfacial electrochemical stability. The 0.03V-Y sample (LiV0.03 Ni0.47 Y0.01 Mn1.49O4) delivers an initial discharge capacity of 132 mAh/g at a 0.1C rate, retaining 94.7% of its capacity after 200 cycles. It also exhibits superior rate capability at a high rate of 5C. This study provides a novel approach for constructing a coherent interface and synergistically optimizing the electrochemical performance of LNMO via dual-element doping.

为提升高电压正极材料LiNi0.5Mn1.5O4(LNMO)的倍率性能与循环稳定性,采用高分子软模板法合成V-Y共掺杂LNMO正极材料,系统研究V、Y元素共掺杂对晶体结构、界面特性及电化学性能的影响。通过XRD、FTIR、SEM、EDS等手段表征材料结构,结合恒电流充放电、循环伏安(CV)和交流阻抗(EIS)等电化学测试分析其性能。结果表明,V-Y共掺杂有效调控LNMO形成无序Fd3m相,促进尖晶石由正八面体向截角八面体转变,形成共格界面,显著提升Li+扩散速率与电子电导率;V-Y共掺杂降低Mn3+含量,抑制Jahn-Teller效应及电极/电解液界面副反应,增强界面电化学稳定性。0.03V-Y样品(LiV0.03Ni0.47Y0.01Mn1.49O4)在0.1C倍率下首次放电比容量达132 mAh/g,循环200次后容量保持率高达94.7%,在5C大倍率下仍表现出优异的倍率性能。本研究为通过双元素掺杂构建共格界面和协同优化LNMO电化学性能提供了新思路。

为提升高电压正极材料LiNi0.5Mn1.5O4(LNMO)的倍率性能与循环稳定性,采用高分子软模板法合成V-Y共掺杂LNMO正极材料,系统研究V、Y元素共掺杂对晶体结构、界面特性及电化学性能的影响。通过XRD、FTIR、SEM、EDS等手段表征材料结构,结合恒电流充放电、循环伏安(CV)和交流阻抗(EIS)等电化学测试分析其性能。结果表明,V-Y共掺杂有效调控LNMO形成无序Fd3m相,促进尖晶石由正八面体向截角八面体转变,形成共格界面,显著提升Li+扩散速率与电子电导率;V-Y共掺杂降低Mn3+含量,抑制Jahn-Teller效应及电极/电解液界面副反应,增强界面电化学稳定性。0.03V-Y样品(LiV0.03Ni0.47Y0.01Mn1.49O4)在0.1C倍率下首次放电比容量达132 mAh/g,循环200次后容量保持率高达94.7%,在5C大倍率下仍表现出优异的倍率性能。本研究为通过双元素掺杂构建共格界面和协同优化LNMO电化学性能提供了新思路。

To enhance the rate capability and cycling stability of the high-voltage cathode material LiNi0.5 Mn1.5O4 (LNMO), a V-Y co-doped LNMO cathode material was synthesized via the polymer soft-template method. The effects of V-Y co-doping on crystal structure, interfacial properties, and electrochemical performance were systematically investigated. The material was characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) among other techniques, and the electrochemical properties were analyzed via galvanostatic charge-discharge, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The results indicate that V-Y co-doping induces the formation of disordered Fd3m phase by effectively regulating LNMO, facilitates the morphology evolution of spinel from regular octahedron to truncated octahedron, and constructs a coherent interface, which significantly enhances the lithium-ion diffusion rate and electronic conductivity. Moreover, V-Y co-doping reduces the Mn3+content, suppresses Jahn-Teller effect and side reactions at the electrode/electrolyte interface, thereby enhancing the interfacial electrochemical stability. The 0.03V-Y sample (LiV0.03 Ni0.47 Y0.01 Mn1.49O4) delivers an initial discharge capacity of 132 mAh/g at a 0.1C rate, retaining 94.7% of its capacity after 200 cycles. It also exhibits superior rate capability at a high rate of 5C. This study provides a novel approach for constructing a coherent interface and synergistically optimizing the electrochemical performance of LNMO via dual-element doping.
