Abstract The lithium titanate (LTO) nanoparticles have been prepared by a chemical and green synthesis method and characterized by XRD, FE-SEM, FTIR, Raman, CV and EIS analysis. The XRD result ensured that the LTO exhibits a cubic spinel structure with the space group of Fd3m. The surface morphology of the prepared anode materials has been studied by FE-SEM and TEM analysis. The LTO nano anode material prepared by the green synthesis (GSLTO) method exhibited better electrochemical cycling stability when compared to the LTO prepared by the chemical (LTO) method. The calculated specific capacitances of 107 F g-1 and 91 F g-1 for LTO and GSLTO samples at a scan rate of 5 mV/s. Based on the obtained results, the green synthesized LTO nano material is suitable as an alternative anode for the lithium ion batteries.

芦荟提取物绿色合成尖晶石钛酸锂纳米负极材料在锂离子电池中的潜在应用

摘要 采用化学和绿色合成方法制备了钛酸锂 (LTO) 纳米颗粒，并通过 XRD、FE-SEM、FTIR、拉曼、CV 和 EIS 分析对其进行了表征。XRD结果确保LTO呈现立方尖晶石结构，空间群为Fd3m。通过FE-SEM和TEM分析研究了制备的负极材料的表面形貌。与化学(LTO)法制备的LTO相比，绿色合成(GSLTO)法制备的LTO纳米阳极材料表现出更好的电化学循环稳定性。LTO 和 GSLTO 样品在 5 mV/s 扫描速率下的计算比电容为 107 F g-1 和 91 F g-1。基于所得结果，绿色合成的 LTO 纳米材料适合作为锂离子电池的替代负极。
