【摘要】 插层化合物Li_xVO₂（0<x<1）是用化学方法从LiVO₂中引出不同数量的Li之后得到的。用原子吸收光谱方法和电位分析法对Li和V的含量以及V的氧化价态做了定量分析。Li_xVO₂的x射线衍射谱线表明,在x值为0.65附近发生了相变。随着Li的引出,晶格常数a和c发生了变化。Li_xVO₂的直流电阻率随着x值减少而减少。另外,用Li_xVO₂作阴极组装成二极电池,并对电池进行了初步实验。更多还原

【Abstract】 Li_xVO₂ are prepared by chemical method based on LiVO₂. X-ray powderdiffraction and quantitative element analysis are studied. The content ofLi is determined by atomic absorption spectrometry and the oxidation stateof Vanadium is determined by chemical analysis using Ce（Ⅳ） as oxidant.The results of X-ray diffraction show that Li_xVO₂ is a single-phase compo-und when 0.7<x<1, Li_xVO₂ is two-phase compound when 0<x<0. 65. Elect-rical resistivity of Li_xVO₂ is reduced with decreasing value of x in Li_xVO₂The preliminary test of the experiment cell by using Li_xVO₂ as positiveelectrode is made.更多还原
