摘要
三氧化钼具有独特的层状结构,主要以三种相态存在:热力学稳定的正交相、热力学介稳的单斜相和六方相。本文介绍了三氧化钼的制备方法,概述了它们电化学脱嵌锂性质的研究现状,探讨了三氧化钼晶体作为电极活性材料的主要影响因素,提出了改进材料电化学性能的方法,展望了三氧化钼研究的发展趋势和应用前景。
Molybdenum trioxides, which exhibit a unique layered structure, form a rich family: the well - known thermodynamically stable normal phase α - MoO3 , metastable phase β - MoO3 and h - MoO3 s in preparation and electrochemical properties of lithium intercalation - detercalation of layered molybdenum trioxides has been introduced. The factors that might influence the electrochemical behaviors of these oxides have been discussed. Further work on improving the performance of materials is suggested. The main application and prospect of molybdenum trioxides are also given in brief.
