摘要
用化学方法从层状化合物LiVO_2中引出0.5个Li后得到Li_(0.5)VO_2,再经过低温真空热处理制备出尖晶石结构化合物LiV_2O_4,类似地处理Li_(0.465)VO_2,得到缺Li的Li_(0.93)V_2O_4,LiV_2O_4和Li_(0.93)V_2O_4的x射线粉末衍射数据表明,二者略有差别,还用LiV_2O_4作为正电极做成二极电池,并进行了初步的实验研究。
LiV2O4, with spinel structure, is prepared under vacuum by heat-treatment of Li0.5VO2 obtained by chemical extraction of 0.5 lithium from the layered compound LiVO2. Similar treatment of Li0.465VO2 results in a cation-deficient spinel Li0.93V2O4. X-ray powder diffraction data show that LiV2O4 is only different slightly from Li0.93V2O4 The preliminary test of the experimental cell by using LiV2O4 as positive electrode is made.
