| Popis: | The K’-bronze Li2.6V6O16+-y was prepared from VO(OPri)2, VO(OBui)3, and LiOR (R = Et, Pr). As determined by x-ray diffraction and electron scanning microscopy, the bronze had a highly textured microstructure. The vanadium(IV) and vanadium(V) contents of the bronze were determined by cyclic voltammetry, and the electrical conductivity was measured in the temperature range 20–400°C. The alkoxide process was shown to ensure good reproducibility of the electrical properties of the material. The electrochemical behavior of the bronze was studied in a 1 M solution of LiClO4 in a propylene carbonate (70 wt %) + dimethoxyethane (30 wt %) mixture in a galvanostatic cycling regime using Li metal counter and reference electrodes |
