采用低温反应法，通过研磨和煅烧合成了亚微米级LiV3O8正极材料。使用Li（ac）中心点2H（2）O（ac =乙酸盐）、NH4VO3和过量H2C2O4中心点2H（2）O的混合物作为起始材料，而不使用任何溶剂。X射线衍射（XRD）、扫描电子显微镜（SEM）、充放电测试和循环伏安（CV）等表征结果表明，350 ℃热处理的样品具有最佳的电化学性能。该低温反应路线是制备高性能LiV3O8正极材料的一条简单而有效的合成路线。(c)2008 Elsevier B.V.保留所有权利。
Submicron-sized LiV3O8 cathode materials were synthesized using a low-temperature reaction route with the help of grinding and the following calcination. A mixture of Li(ac)center dot 2H(2)O(ac = acetate), NH4VO3 and excess H2C2O4 center dot 2H(2)O was used as starting material without any solvent. Characterization results of X-ray diffraction (XRD), scanning electron microscopy (SEM),charge-discharge test, and cyclic voltammogram (CV) indicated that the sample heat-treated at 350 degrees C shows the best electrochemical performance. This low-temperature reaction route is a simple but efficient synthesis route for preparing high-performance LiV3O8 cathode material. (c) 2008 Elsevier B.V. All rights reserved.
