The existence of the known vanadium bronzes MxV2O5 (M = Li, Cu) is confirmed, and the composition ranges of the related solid solutions are determined. β-LixV2O5 (0.22 ≤ x ≤ 0.49) and γ-LixV2O5 (0.88 ≤ x ≤ 1.0) are shown to dissolve Cu, forming LixCuyV2O5 solid solutions with y = 0.72 – 1.48x and y = 0.58 – 0.18x, respectively. CuxLiyV2O5 solid solutions (y = 0.51 – 0.76 x) are only obtained from β-CuxV2O5 (0.24 ≤ x ≤ 0.67). β-LixV2O5 and β-CuxV2O5 form a continuous series of solid solutions. The cathodic properties of Li–V2O5–Cu materials in high-temperature pulsed lithium batteries are investigated Полный текст |
