摘要
采用改进的高温固相法合成不同金属离子掺杂的Li4Ti5O12,研究了不同金属元素掺杂对其晶型、相结构、颗粒形貌以及电化学性能的影响。结果表明:离子掺杂能降低电极极化,提升锂离子扩散系数,改善电化学性能。
Anode material doped Li4Ti5O12 with metal ion was successfully synthesized by a simple high-energy ball milling assisted modified solid-state method. The impact of metal ion doping on crystalline structure, phase structure, morphology and electrochemical performance of Li4Ti5O12 was investigated. The results show that the doping can obviously reduce electrode polarization and improve the diffusion coefficient and electrochemical performance.
