中文摘要：

以V2O5晶体粉末、H2O2（30％（质量分数））为原材料，采用溶胶-凝胶法，通过溶剂替换工艺在常压下成功地制备了纳米多孔结构的V2O5气凝胶材料。采用扫描电镜（SEM）、透射电镜（TEM）、比表面积仪（BET）、粉末X射线衍射（XRD）、傅立叶红外分光光度计（FTIR）和拉曼光谱仪（Raman）等方法分别观察和测试了V2O5气凝胶材料的形貌、晶态结构及分子振动。SEM、TEM观察表明，常压干燥制备的V2O5气凝胶呈比较规则的具有层状结构的纤维网络状结构；XRD分析表明，由于结合水插入层间而使V2O5气凝胶的层间距有明显的增加；BET测试结果表明，常压干燥制备的V2O5气凝胶材料的平均孔径为16nm，最大孔径为78nm。

英文摘要：

Ambient pressure dried V2O5 aerogels are prepared from crystalline V2O5 and H2O2 （30wt%） by solgel method and solvent exchange process. The microstructure, crystalline structure and vibration modes of the V2O5 aerogels are investigated by SEM, TEM, XRD, FTIR and Raman. The experimental results show that ambient dried V2O5 aerogels exhibit a fibrous microstructure, the distance of inter-layers increases distinctly, and the average pore diameter is about 16nm. These properties indicate that the ambient pressure dried V2O5 aerogels can be used as good cathode material for lithium batteries.
