以LiOH·H2O、NH4VO3和C6H8O7·H2O为原料，在温度和功率控制的科学微波炉中烧结凝胶，合成Li1+xV3O8材料，称为微波溶胶-凝胶路线。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、循环伏安图（CV）和充放电测试对不同持续时间的微波烧结样品进行研究，以评估烧结时间的影响。结果表明，在 400°C 下微波烧结 100 至 150 分钟是 MW-溶胶-凝胶路线制备正极材料 Li1+xV3O8 的更合适选择。我们的论文表明微波溶胶-凝胶路线是制备Li1+xV3O8正极材料的快速有效的合成方法。
Li1+xV3O8material was synthesized by sintering the gel starting from LiOH·H2O, NH4VO3and C6H8O7·H2O in a scientific microwave oven with temperature and power control, which is called microwave sol–gel route. The samples sintered by microwave in various durations were investigated via X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammograms (CVs) and charge/discharge test to evaluate the effect of sintering duration. It shows that sintering duration in microwave at 400°C between 100 and 150min is a more suitable option for MW-sol–gel route to prepare cathode material Li1+xV3O8. Our paper suggests that the microwave sol–gel route is a rapid and efficient synthetic method for preparing Li1+xV3O8cathode material.
